Wiki Export — Knowledge Graph Export

You are exporting the wiki's wikilink graph to structured formats so it can be used in external tools (Gephi, Neo4j, custom scripts, browser visualization).

Before You Start

  1. Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (inline @name override → walk up CWD for .env → global config → prompt setup). This gives OBSIDIAN_VAULT_PATH
  2. Confirm the vault has pages to export — if fewer than 5 pages exist, warn the user and stop

Project Filter (optional)

If the user's invocation includes a project name — e.g. /wiki-export prismor, "export the prismor project", "export project:security" — activate project filter mode:

  1. Extract the project name from the argument or phrase. Normalise: lowercase, strip the word "project".
  2. Keep only pages where either condition holds:
    • The page id starts with projects/<name>/ (path-based match)
    • The page's tags array contains <name> (tag-based match)
  3. Drop any edge where either endpoint was excluded.
  4. Note the filter in the summary: (filtered: project:<name> — X of Y pages)
  5. Set graph.graph.filter = "project:<name>" in the JSON output.

If both a project filter and a visibility filter are active, apply both (project filter first, then visibility filter on the remaining set).

Visibility Filter (optional)

By default, all pages are exported regardless of visibility tags. This preserves existing behavior.

If the user requests a filtered export — phrases like "public export", "user-facing export", "exclude internal", "no internal pages" — activate visibility filtered mode:

  • Build a blocked tag set: {visibility/internal, visibility/pii}
  • Skip any page whose frontmatter tags contain a blocked tag when building the node list
  • Skip any edge where either endpoint was excluded
  • Note the filter in the summary: (filtered: visibility/internal, visibility/pii excluded)

Pages with no visibility/ tag, or tagged visibility/public, are always included.

Step 1: Build the Node and Edge Lists

Glob all .md files in the vault (excluding _archives/, _raw/, _readouts/, .obsidian/, index.md, log.md, _insights.md). Apply any active filters (project and/or visibility) after collecting the full file list.

For each page, extract from frontmatter:

  • id — relative path from vault root, without .md extension (e.g. concepts/transformers)
  • label — title field from frontmatter, or filename if missing
  • category — directory prefix (concepts, entities, skills, references, synthesis, projects, or journal)
  • tags — array from frontmatter tags field
  • summary — frontmatter summary field if present

This is your node list.

For each page, Grep the body for \[\[.*?\]\] to extract all wikilinks:

  • Parse each [[target]] or [[target|display]] — use the target part only
  • Resolve the target to a node id (normalize: lowercase, spaces→hyphens, strip .md)
  • Skip links that point outside the node list (broken links)
  • Each resolved link becomes an edge: {source: page_id, target: linked_id, relation: "wikilink", confidence: "EXTRACTED"}
  • If the linking sentence ends with ^[inferred] or ^[ambiguous], override confidence accordingly

Typed edge enrichment: After building the wikilink edge list, read each page's relationships: frontmatter block. For each {target, type} entry:

  • The target YAML value is a quoted wikilink string such as "[[concepts/lstm]]". Strip the surrounding [[ and ]] characters, then apply the same normalization (lowercase, spaces→hyphens, strip .md) to get the node id.
  • Skip entries whose resolved target is not in the node list (broken link)
  • If an edge for this (source, target) pair already exists, override its relation field with the typed value (e.g., "contradicts") and set typed: true
  • If no edge exists yet for this pair, add one: {source: page_id, target: target_id, relation: <type>, confidence: "EXTRACTED", typed: true}

This means relation: "wikilink" is the default for plain untyped links; a relationships: entry promotes it to a named semantic type. Edges that originated from both a body wikilink and a relationships: entry keep a single record — the typed version wins.

This is your edge list.

Step 2: Assign Community IDs

Group pages into communities by tag clustering:

  • Pages sharing the same dominant tag belong to the same community
  • Dominant tag = the first tag in the page's frontmatter tags array
  • Pages with no tags get community id null
  • Number communities starting from 0, ordered by size descending (largest community = 0)

This enables community-based coloring in the HTML visualization and tools like Gephi.

Step 3: Write the Output Files

Create wiki-export/ at the vault root if it doesn't exist. Write all five files:


3a. graph.json

NetworkX node_link format — standard for graph tools and scripts:

{
  "directed": false,
  "multigraph": false,
  "graph": {
    "exported_at": "<ISO timestamp>",
    "vault": "<OBSIDIAN_VAULT_PATH>",
    "total_nodes": N,
    "total_edges": M
  },
  "nodes": [
    {
      "id": "concepts/transformers",
      "label": "Transformer Architecture",
      "category": "concepts",
      "tags": ["ml", "architecture"],
      "summary": "The attention-based architecture introduced in Attention Is All You Need.",
      "community": 0
    }
  ],
  "links": [
    {
      "source": "concepts/transformers",
      "target": "entities/vaswani",
      "relation": "wikilink",
      "confidence": "EXTRACTED"
    },
    {
      "source": "concepts/transformers",
      "target": "concepts/lstm",
      "relation": "contradicts",
      "confidence": "EXTRACTED",
      "typed": true
    }
  ]
}

3b. graph.graphml

GraphML XML format — loadable in Gephi, yEd, and Cytoscape:

<?xml version="1.0" encoding="UTF-8"?>
<graphml xmlns="http://graphml.graphdrawing.org/graphml">
  <key id="label" for="node" attr.name="label" attr.type="string"/>
  <key id="category" for="node" attr.name="category" attr.type="string"/>
  <key id="tags" for="node" attr.name="tags" attr.type="string"/>
  <key id="community" for="node" attr.name="community" attr.type="int"/>
  <key id="relation" for="edge" attr.name="relation" attr.type="string"/>
  <key id="type" for="edge" attr.name="type" attr.type="string"/>
  <key id="confidence" for="edge" attr.name="confidence" attr.type="string"/>
  <graph id="wiki" edgedefault="undirected">
    <node id="concepts/transformers">
      <data key="label">Transformer Architecture</data>
      <data key="category">concepts</data>
      <data key="tags">ml, architecture</data>
      <data key="community">0</data>
    </node>
    <!-- Untyped wikilink — no <data key="type"> element -->
    <edge source="concepts/transformers" target="entities/vaswani">
      <data key="relation">wikilink</data>
      <data key="confidence">EXTRACTED</data>
    </edge>
    <!-- Typed edge from relationships: block -->
    <edge source="concepts/transformers" target="concepts/lstm">
      <data key="relation">contradicts</data>
      <data key="type">contradicts</data>
      <data key="confidence">EXTRACTED</data>
    </edge>
  </graph>
</graphml>

Write one <node> per page and one <edge> per link. For typed edges (those where typed: true in the edge list), emit both <data key="relation"> with the semantic type value and <data key="type"> with the same value — this keeps relation readable for tools that already consume it while letting type-aware tools filter on the dedicated type key. Untyped wikilinks omit the <data key="type"> element entirely.


3c. cypher.txt

Neo4j Cypher MERGE statements — paste into Neo4j Browser or run with cypher-shell:

// Wiki knowledge graph export — <TIMESTAMP>
// Load with: cypher-shell -u neo4j -p password < cypher.txt

// Nodes
MERGE (n:Page {id: "concepts/transformers"}) SET n.label = "Transformer Architecture", n.category = "concepts", n.tags = ["ml","architecture"], n.community = 0;
MERGE (n:Page {id: "entities/vaswani"}) SET n.label = "Ashish Vaswani", n.category = "entities", n.tags = ["person","ml"], n.community = 0;
MERGE (n:Page {id: "concepts/lstm"}) SET n.label = "LSTM", n.category = "concepts", n.tags = ["ml","rnn"], n.community = 0;

// Relationships
// Untyped wikilinks use [:WIKILINK]
MATCH (a:Page {id: "concepts/transformers"}), (b:Page {id: "entities/vaswani"}) MERGE (a)-[:WIKILINK {relation: "wikilink", confidence: "EXTRACTED"}]->(b);
// Typed edges use the relationship type as the label (UPPERCASE)
MATCH (a:Page {id: "concepts/transformers"}), (b:Page {id: "concepts/lstm"}) MERGE (a)-[:CONTRADICTS {relation: "contradicts", confidence: "EXTRACTED"}]->(b);

Write one MERGE node statement per page, then one MATCH/MERGE relationship statement per edge. For typed edges, use the type value uppercased as the Cypher relationship label (e.g., contradicts → [:CONTRADICTS], derived_from → [:DERIVED_FROM]). Untyped wikilinks always use [:WIKILINK].


3d. postgres.sql

Plain SQL — loadable into any Postgres database (local, Supabase, RDS, Neon, …) with psql -f postgres.sql or a migration runner. Two tables: wiki_pages (nodes) and wiki_edges (links), with ON CONFLICT upserts so re-running the export is safe and idempotent, mirroring the MERGE semantics of cypher.txt.

-- Wiki knowledge graph export — <TIMESTAMP>
-- Load with: psql -d yourdb -f postgres.sql

CREATE TABLE IF NOT EXISTS wiki_pages (
  id        TEXT PRIMARY KEY,
  label     TEXT NOT NULL,
  category  TEXT,
  tags      JSONB NOT NULL DEFAULT '[]'::jsonb,
  summary   TEXT,
  community INT
);

CREATE TABLE IF NOT EXISTS wiki_edges (
  source     TEXT NOT NULL REFERENCES wiki_pages(id) ON DELETE CASCADE,
  target     TEXT NOT NULL REFERENCES wiki_pages(id) ON DELETE CASCADE,
  relation   TEXT NOT NULL DEFAULT 'wikilink',
  confidence TEXT,
  typed      BOOLEAN NOT NULL DEFAULT false,
  PRIMARY KEY (source, target, relation)
);

CREATE INDEX IF NOT EXISTS wiki_edges_source_idx ON wiki_edges(source);
CREATE INDEX IF NOT EXISTS wiki_edges_target_idx ON wiki_edges(target);

-- Nodes
INSERT INTO wiki_pages (id, label, category, tags, summary, community)
VALUES ('concepts/transformers', 'Transformer Architecture', 'concepts', '["ml","architecture"]'::jsonb, 'The attention-based architecture introduced in Attention Is All You Need.', 0)
ON CONFLICT (id) DO UPDATE SET
  label = EXCLUDED.label, category = EXCLUDED.category, tags = EXCLUDED.tags,
  summary = EXCLUDED.summary, community = EXCLUDED.community;

-- Edges
-- Untyped wikilink
INSERT INTO wiki_edges (source, target, relation, confidence, typed)
VALUES ('concepts/transformers', 'entities/vaswani', 'wikilink', 'EXTRACTED', false)
ON CONFLICT (source, target, relation) DO UPDATE SET confidence = EXCLUDED.confidence, typed = EXCLUDED.typed;

-- Typed edge from relationships: block
INSERT INTO wiki_edges (source, target, relation, confidence, typed)
VALUES ('concepts/transformers', 'concepts/lstm', 'contradicts', 'EXTRACTED', true)
ON CONFLICT (source, target, relation) DO UPDATE SET confidence = EXCLUDED.confidence, typed = EXCLUDED.typed;

Write one INSERT ... ON CONFLICT (id) DO UPDATE statement per page (values escaped: single quotes doubled, tags serialized as a JSON array literal cast to jsonb), then one INSERT ... ON CONFLICT (source, target, relation) DO UPDATE per edge. relation stays lowercase here (unlike the uppercased Cypher relationship label) since it's a plain column value, not a schema identifier — this keeps it directly filterable with WHERE relation = 'contradicts' or joinable without case-folding. typed is true only for edges promoted by a relationships: frontmatter entry; plain wikilinks stay false.

Skip pages whose id collides only after the ON CONFLICT clause fires from a prior run — do not attempt to deduplicate synthetic multi-edges (e.g. same source/target with both a wikilink and a typed relation) since the composite primary key (source, target, relation) already keeps them as distinct rows, matching the "typed version wins" merge behavior of graph.json/graph.graphml at the query layer (SELECT * FROM wiki_edges WHERE source=$1 AND target=$2 ORDER BY typed DESC LIMIT 1).


3e. graph.html

A self-contained interactive visualization using the vis.js CDN (no local dependencies). The user opens this file in any browser — no server needed.

Build the HTML file by:

  1. Generating a JSON array of node objects for vis.js:
{id: "concepts/transformers", label: "Transformer Architecture", color: {background: "#4E79A7"}, size: <degree * 3 + 8>, title: "concepts | #ml #architecture", community: 0}
  • Color by community (cycle through: #4E79A7, #F28E2B, #E15759, #76B7B2, #59A14F, #EDC948, #B07AA1, #FF9DA7, #9C755F, #BAB0AC)
  • Size by degree (incoming + outgoing link count): size = degree * 3 + 8, capped at 60
  • title = tooltip text shown on hover: category, tags, summary (if available)
  1. Generating a JSON array of edge objects for vis.js:
// Untyped wikilink
{from: "concepts/transformers", to: "entities/vaswani", dashes: false, width: 1, color: {color: "#666", opacity: 0.6}, title: "wikilink"}
// Typed edge
{from: "concepts/transformers", to: "concepts/lstm", dashes: false, width: 2, color: {color: "#E15759", opacity: 0.8}, label: "contradicts", font: {size: 9, color: "#ccc"}, title: "contradicts"}
  • dashes: true for INFERRED edges
  • dashes: [4,8] for AMBIGUOUS edges
  • Typed edges (typed: true): set width: 2, add a label field showing the type, and apply a type-specific color:
Type Edge color
extends #59A14F (green)
implements #4E79A7 (blue)
contradicts #E15759 (red)
derived_from #F28E2B (orange)
uses #76B7B2 (teal)
replaces #B07AA1 (purple)
related_to #BAB0AC (grey — same as untyped)

Untyped wikilink edges keep the existing #666 grey color and no label.

Step 3.5: OKF Bundle Export (optional)

Run this step only when the user asks for OKF / a markdown bundle (phrases like "export to OKF", "OKF bundle", "open knowledge format", "export as markdown bundle"). It is additive — the five graph files above are always produced; this writes an extra full-fidelity markdown bundle.

The five graph files are a lossy projection (graph skeleton only). An OKF bundle is the actual page bodies, so an export→wiki-import round-trip through OKF preserves full content, and the bundle drops straight into MkDocs, Notion, Hugo, GitHub's renderer, or any Open Knowledge Format consumer.

Canonical frontmatter mapping (obsidian-wiki ⇄ OKF)

This table is the single source of truth for the mapping; wiki-import references it for the reverse direction.

OKF key ← export from → import to Notes
type (required) category, title-cased category (lower-cased) concepts→Concept, entities→Entity, skills→Skill, references→Reference, synthesis→Synthesis, projects→Project, journal→Journal. OKF requires type; consumers tolerate any string.
title title title Verbatim.
description summary summary Our one-line summary: is exactly OKF's description (used in index.md entries).
tags tags tags Verbatim list. visibility/* system tags pass through unchanged.
generated updated → generated.at; by is the producer updated ← generated.at Write generated: { by: obsidian-wiki/<version>, at: <datetime> }, taking <version> from obsidian-wiki --version (plain obsidian-wiki if the CLI isn't installed). OKF §5 requires every timestamp to be a datetime with an explicit offset, so a date-only updated: 2026-04-12 becomes 2026-04-12T00:00:00Z. Replaces v0.1's timestamp, which is no longer written.
sources sources (list of strings) sources (list of strings) OKF sources is a list of objects with a required resource, so each native string becomes - resource: <string>. Opaque strings like conversation:2026-04-12 are valid: §5.1 allows scope descriptors a consumer can't follow. Emit nothing else per entry, so import recovers the exact strings.
status lifecycle — (native lifecycle is preserved) draft → draft; reviewed, verified, disputed → stable; archived → deprecated. Omit status when lifecycle is absent (absent means stable in OKF).
verified _meta/trust-ledger.json entry for the page — (preserved verbatim) Only when the page has a ledger entry: verified: { by: human:vault-owner, at: <entry reviewed_at> }. trust-record only writes entries a human approved with --approved, so the human: actor is accurate and gives the page OKF's human-reviewed tier (§5.3). Never derive verified from lifecycle alone.
resource first sources: entry iff it is an http(s):// URL — Optional; omit when no source URL. Most pages describe abstract knowledge and have none.
(extensions) category, created, updated, relationships, lifecycle, lifecycle_changed, tier, base_confidence, … preserved verbatim OKF §4.1 requires consumers to preserve unknown keys. Writing our native keys as OKF extension frontmatter is what makes the round-trip lossless — on import, preserved category/created/updated/lifecycle are preferred over re-deriving from type/generated/status. (updated rides along because generated.at must be a full datetime, so a date-only updated would otherwise come back as midnight UTC.) sources is not an extension any more: it's a spec field (row above).
Steps

Reuse the node list from Step 1 (with any active project/visibility filters already applied). Write a directory tree under wiki-export/okf/:

  1. One file per in-scope page. For each page, parse its frontmatter, apply the mapping table above to build the OKF frontmatter (required type first, then title, description, tags, generated, status, verified, sources, optional resource, then the preserved extension keys), transform the body links (below), and write to wiki-export/okf/<category>/<slug>.md — same relative path the page has in the vault.

  2. Body link transform ([[wikilinks]] → standard markdown links):

    • [[concepts/transformers]] → [<target title>](<file-relative path>.md), e.g. from entities/foo.md a link to concepts/transformers becomes [Transformer Architecture](../concepts/transformers.md). Link text = the target page's title (fall back to the target id if unknown).
    • [[target|display]] → [display](<rel path>.md).
    • Use file-relative paths (../concepts/x.md), never /-absolute — /-rooted links break GitHub rendering. (This matches knowledge-catalog's own production agent.)
    • Compute that relative path from the target file path, not the bare page id: normalize the wikilink target to its page id, append .md, then compute relpath(<target-file>, <source-file-dir>). Never call relpath() on the id before adding .md.
    • This is required for the common "folder note" layout where a page id exists both as a file and as a directory prefix, e.g. projects/social-twitter.md plus projects/social-twitter/.... From projects/social-twitter/concepts/mem0-memory-analysis.md, a link to [[projects/social-twitter]] must export to ../../social-twitter.md, not ...md.
    • Resolve link targets with the same normalization used in Step 1 (lowercase, spaces→hyphens, strip .md). Handle unresolved targets by form, so forward-references survive the round-trip:
      • Resolves to an in-scope page → relative markdown link to it.
      • Path-form target (contains a /, e.g. [[concepts/attention-mechanism]]) with no page yet, and not excluded by an active filter → still emit the relative markdown link. OKF §11 forbids rejecting a bundle over a broken cross-link, and keeping the link makes the user's forward-references lossless on re-import. (Verified on st3ve: dropping these silently deleted real [[wikilinks]].)
      • Excluded by an active project/visibility filter → plain text. Do not emit a path pointing into filtered-out content.
      • Bare-title target with no match (e.g. [[tractorex]] when no such page exists in scope) → plain text; there is no reliable path to write.
    • Leave existing external http(s):// links and # Citations sections untouched.
  3. Generate index.md files (OKF §8 progressive disclosure; these contain no per-entry frontmatter):

    • Bundle root wiki-export/okf/index.md — a # Subdirectories section listing each category folder: * [<category>](<category>/index.md) - <one-line description of the category>. This is the only index permitted frontmatter: add a single key okf_version: "0.2" (OKF §8, §12).
    • One index.md per category folder listing its pages: * [<title>](<slug>.md) - <description from the page's summary>.
  4. Write log.md from the vault root's log.md, reshaped to OKF §9, which requires ## YYYY-MM-DD date headings, newest first. Our log is a flat, oldest-first list of - [<timestamp>] VERB key=value … lines, so: start with # Wiki Update Log; group lines by the date part of <timestamp>; emit groups newest first under ## <date>; render each line as * **<Verb>**: <rest of line>, with the verb title-cased (INGEST → Ingest). Keep lines that don't match the pattern under the date of the line above them, verbatim after * . wiki-import ignores log.md, so this costs nothing on the round-trip.

  5. Filters. Honor the same project/visibility filters as the graph export — filtered pages are omitted from the bundle and their inbound links degrade to plain text per step 2.

Excluded from the bundle (same as the graph export): _archives/, _raw/, _readouts/, .obsidian/, _insights.md, _meta/*.base, and the vault root index.md (regenerated above).


Step 4: Print Summary

Wiki export complete → wiki-export/
  graph.json    — N nodes, M edges (NetworkX node_link format)
  graph.graphml — N nodes, M edges (Gephi / yEd / Cytoscape)
  cypher.txt    — N MERGE nodes + M MERGE relationships (Neo4j)
  postgres.sql  — N upsert rows (wiki_pages) + M upsert rows (wiki_edges) (any Postgres)
  graph.html    — interactive browser visualization (open in any browser)

Append this line only when the OKF bundle was produced (Step 3.5):

  okf/          — OKF v0.2 markdown bundle (N pages, lossless; import via wiki-import)

Append filter notes when active:

  (filtered: project:prismor — 19 of 67 pages)
  (filtered: X of Y pages excluded — visibility/internal, visibility/pii)

Only include lines for filters that were actually applied.

Notes

  • Re-running is safe — all output files (and the okf/ bundle) are overwritten on each run
  • Broken wikilinks are skipped — only edges to pages that exist in the vault are exported; in the OKF bundle, a wikilink to a missing/filtered page degrades to plain text
  • OKF is the lossless format — graph.json reconstructs only stubs on import, while the okf/ bundle preserves full page bodies. Use OKF for vault-to-vault transfer and external markdown tools (MkDocs, Notion, GitHub); use the graph files for analysis tools (Gephi, Neo4j)
  • The wiki-export/ directory should be gitignored if the vault is version-controlled — these are derived artifacts
  • graph.json is the primary format — the others are derived from it. If a future tool supports graph queries natively, point it at graph.json

16You are exporting the wiki's wikilink graph to structured formats so it can be used in external tools (Gephi, Neo4j, custom scripts, browser visualization).
17 
18## Before You Start
19 
201. **Resolve config** — follow the Config Resolution Protocol in `llm-wiki/SKILL.md` (inline `@name` override → walk up CWD for `.env` → global config → prompt setup). This gives `OBSIDIAN_VAULT_PATH`
212. Confirm the vault has pages to export — if fewer than 5 pages exist, warn the user and stop
22 
23## Project Filter (optional)
24 
25If the user's invocation includes a project name — e.g. `/wiki-export prismor`, `"export the prismor project"`, `"export project:security"` — activate **project filter mode**:
26 
271. **Extract the project name** from the argument or phrase. Normalise: lowercase, strip the word "project".
282. Keep only pages where **either** condition holds:
29 - The page `id` starts with `projects/<name>/` (path-based match)
30 - The page's `tags` array contains `<name>` (tag-based match)
313. Drop any edge where either endpoint was excluded.
324. Note the filter in the summary: `(filtered: project:<name> — X of Y pages)`
335. Set `graph.graph.filter = "project:<name>"` in the JSON output.
34 
35If both a project filter and a visibility filter are active, apply both (project filter first, then visibility filter on the remaining set).
36 
37## Visibility Filter (optional)
38 
39By default, **all pages are exported** regardless of visibility tags. This preserves existing behavior.
40 
41If the user requests a filtered export — phrases like **"public export"**, **"user-facing export"**, **"exclude internal"**, **"no internal pages"** — activate **visibility filtered mode**:
42 
43- Build a **blocked tag set**: `{visibility/internal, visibility/pii}`
44- Skip any page whose frontmatter tags contain a blocked tag when building the node list
45- Skip any edge where either endpoint was excluded
46- Note the filter in the summary: `(filtered: visibility/internal, visibility/pii excluded)`
47 
48Pages with no `visibility/` tag, or tagged `visibility/public`, are always included.
49 
50## Step 1: Build the Node and Edge Lists
51 
52Glob all `.md` files in the vault (excluding `_archives/`, `_raw/`, `_readouts/`, `.obsidian/`, `index.md`, `log.md`, `_insights.md`). Apply any active filters (project and/or visibility) after collecting the full file list.
53 
54For each page, extract from frontmatter:
55- `id` — relative path from vault root, without `.md` extension (e.g. `concepts/transformers`)
56- `label` — `title` field from frontmatter, or filename if missing
57- `category` — directory prefix (`concepts`, `entities`, `skills`, `references`, `synthesis`, `projects`, or `journal`)
58- `tags` — array from frontmatter tags field
59- `summary` — frontmatter `summary` field if present
60 
61This is your **node list**.
62 
63For each page, Grep the body for `\[\[.*?\]\]` to extract all wikilinks:
64- Parse each `[[target]]` or `[[target|display]]` — use the target part only
65- Resolve the target to a node id (normalize: lowercase, spaces→hyphens, strip `.md`)
66- Skip links that point outside the node list (broken links)
67- Each resolved link becomes an edge: `{source: page_id, target: linked_id, relation: "wikilink", confidence: "EXTRACTED"}`
68- If the linking sentence ends with `^[inferred]` or `^[ambiguous]`, override `confidence` accordingly
69 
70**Typed edge enrichment:** After building the wikilink edge list, read each page's `relationships:` frontmatter block. For each `{target, type}` entry:
71- The `target` YAML value is a quoted wikilink string such as `"[[concepts/lstm]]"`. Strip the surrounding `[[` and `]]` characters, then apply the same normalization (lowercase, spaces→hyphens, strip `.md`) to get the node id.
72- Skip entries whose resolved target is not in the node list (broken link)
73- If an edge for this `(source, target)` pair already exists, override its `relation` field with the typed value (e.g., `"contradicts"`) and set `typed: true`
74- If no edge exists yet for this pair, add one: `{source: page_id, target: target_id, relation: <type>, confidence: "EXTRACTED", typed: true}`
75 
76This means `relation: "wikilink"` is the default for plain untyped links; a `relationships:` entry promotes it to a named semantic type. Edges that originated from both a body wikilink and a `relationships:` entry keep a single record — the typed version wins.
77 
78This is your **edge list**.
79 
80## Step 2: Assign Community IDs
81 
82Group pages into communities by tag clustering:
83- Pages sharing the same dominant tag belong to the same community
84- Dominant tag = the first tag in the page's frontmatter tags array
85- Pages with no tags get community id `null`
86- Number communities starting from 0, ordered by size descending (largest community = 0)
87 
88This enables community-based coloring in the HTML visualization and tools like Gephi.
89 
90## Step 3: Write the Output Files
91 
92Create `wiki-export/` at the vault root if it doesn't exist. Write all five files:
93 
94---
95 
96### 3a. `graph.json`
97 
98NetworkX node_link format — standard for graph tools and scripts:
99 
100```json
101{
102 "directed": false,
103 "multigraph": false,
104 "graph": {
105 "exported_at": "<ISO timestamp>",
106 "vault": "<OBSIDIAN_VAULT_PATH>",
107 "total_nodes": N,
108 "total_edges": M
109 },
110 "nodes": [
111 {
112 "id": "concepts/transformers",
113 "label": "Transformer Architecture",
114 "category": "concepts",
115 "tags": ["ml", "architecture"],
116 "summary": "The attention-based architecture introduced in Attention Is All You Need.",
117 "community": 0
118 }
119 ],
120 "links": [
121 {
122 "source": "concepts/transformers",
123 "target": "entities/vaswani",
124 "relation": "wikilink",
125 "confidence": "EXTRACTED"
126 },
127 {
128 "source": "concepts/transformers",
129 "target": "concepts/lstm",
130 "relation": "contradicts",
131 "confidence": "EXTRACTED",
132 "typed": true
133 }
134 ]
135}
136```
137 
138---
139 
140### 3b. `graph.graphml`
141 
142GraphML XML format — loadable in Gephi, yEd, and Cytoscape:
143 
144```xml
145<?xml version="1.0" encoding="UTF-8"?>
146<graphml xmlns="http://graphml.graphdrawing.org/graphml">
147 <key id="label" for="node" attr.name="label" attr.type="string"/>
148 <key id="category" for="node" attr.name="category" attr.type="string"/>
149 <key id="tags" for="node" attr.name="tags" attr.type="string"/>
150 <key id="community" for="node" attr.name="community" attr.type="int"/>
151 <key id="relation" for="edge" attr.name="relation" attr.type="string"/>
152 <key id="type" for="edge" attr.name="type" attr.type="string"/>
153 <key id="confidence" for="edge" attr.name="confidence" attr.type="string"/>
154 <graph id="wiki" edgedefault="undirected">
155 <node id="concepts/transformers">
156 <data key="label">Transformer Architecture</data>
157 <data key="category">concepts</data>
158 <data key="tags">ml, architecture</data>
159 <data key="community">0</data>
160 </node>
161 <!-- Untyped wikilink — no <data key="type"> element -->
162 <edge source="concepts/transformers" target="entities/vaswani">
163 <data key="relation">wikilink</data>
164 <data key="confidence">EXTRACTED</data>
165 </edge>
166 <!-- Typed edge from relationships: block -->
167 <edge source="concepts/transformers" target="concepts/lstm">
168 <data key="relation">contradicts</data>
169 <data key="type">contradicts</data>
170 <data key="confidence">EXTRACTED</data>
171 </edge>
172 </graph>
173</graphml>
174```
175 
176Write one `<node>` per page and one `<edge>` per link. For typed edges (those where `typed: true` in the edge list), emit both `<data key="relation">` with the semantic type value **and** `<data key="type">` with the same value — this keeps `relation` readable for tools that already consume it while letting type-aware tools filter on the dedicated `type` key. Untyped wikilinks omit the `<data key="type">` element entirely.
177 
178---
179 
180### 3c. `cypher.txt`
181 
182Neo4j Cypher `MERGE` statements — paste into Neo4j Browser or run with `cypher-shell`:
183 
184```cypher
185// Wiki knowledge graph export — <TIMESTAMP>
186// Load with: cypher-shell -u neo4j -p password < cypher.txt
187 
188// Nodes
189MERGE (n:Page {id: "concepts/transformers"}) SET n.label = "Transformer Architecture", n.category = "concepts", n.tags = ["ml","architecture"], n.community = 0;
190MERGE (n:Page {id: "entities/vaswani"}) SET n.label = "Ashish Vaswani", n.category = "entities", n.tags = ["person","ml"], n.community = 0;
191MERGE (n:Page {id: "concepts/lstm"}) SET n.label = "LSTM", n.category = "concepts", n.tags = ["ml","rnn"], n.community = 0;
192 
193// Relationships
194// Untyped wikilinks use [:WIKILINK]
195MATCH (a:Page {id: "concepts/transformers"}), (b:Page {id: "entities/vaswani"}) MERGE (a)-[:WIKILINK {relation: "wikilink", confidence: "EXTRACTED"}]->(b);
196// Typed edges use the relationship type as the label (UPPERCASE)
197MATCH (a:Page {id: "concepts/transformers"}), (b:Page {id: "concepts/lstm"}) MERGE (a)-[:CONTRADICTS {relation: "contradicts", confidence: "EXTRACTED"}]->(b);
198```
199 
200Write one `MERGE` node statement per page, then one `MATCH`/`MERGE` relationship statement per edge. For typed edges, use the `type` value uppercased as the Cypher relationship label (e.g., `contradicts` → `[:CONTRADICTS]`, `derived_from` → `[:DERIVED_FROM]`). Untyped wikilinks always use `[:WIKILINK]`.
201 
202---
203 
204### 3d. `postgres.sql`
205 
206Plain SQL — loadable into any Postgres database (local, Supabase, RDS, Neon, …) with `psql -f postgres.sql` or a migration runner. Two tables: `wiki_pages` (nodes) and `wiki_edges` (links), with `ON CONFLICT` upserts so re-running the export is safe and idempotent, mirroring the `MERGE` semantics of `cypher.txt`.
207 
208```sql
209-- Wiki knowledge graph export — <TIMESTAMP>
210-- Load with: psql -d yourdb -f postgres.sql
211 
212CREATE TABLE IF NOT EXISTS wiki_pages (
213 id TEXT PRIMARY KEY,
214 label TEXT NOT NULL,
215 category TEXT,
216 tags JSONB NOT NULL DEFAULT '[]'::jsonb,
217 summary TEXT,
218 community INT
219);
220 
221CREATE TABLE IF NOT EXISTS wiki_edges (
222 source TEXT NOT NULL REFERENCES wiki_pages(id) ON DELETE CASCADE,
223 target TEXT NOT NULL REFERENCES wiki_pages(id) ON DELETE CASCADE,
224 relation TEXT NOT NULL DEFAULT 'wikilink',
225 confidence TEXT,
226 typed BOOLEAN NOT NULL DEFAULT false,
227 PRIMARY KEY (source, target, relation)
228);
229 
230CREATE INDEX IF NOT EXISTS wiki_edges_source_idx ON wiki_edges(source);
231CREATE INDEX IF NOT EXISTS wiki_edges_target_idx ON wiki_edges(target);
232 
233-- Nodes
234INSERT INTO wiki_pages (id, label, category, tags, summary, community)
235VALUES ('concepts/transformers', 'Transformer Architecture', 'concepts', '["ml","architecture"]'::jsonb, 'The attention-based architecture introduced in Attention Is All You Need.', 0)
236ON CONFLICT (id) DO UPDATE SET
237 label = EXCLUDED.label, category = EXCLUDED.category, tags = EXCLUDED.tags,
238 summary = EXCLUDED.summary, community = EXCLUDED.community;
239 
240-- Edges
241-- Untyped wikilink
242INSERT INTO wiki_edges (source, target, relation, confidence, typed)
243VALUES ('concepts/transformers', 'entities/vaswani', 'wikilink', 'EXTRACTED', false)
244ON CONFLICT (source, target, relation) DO UPDATE SET confidence = EXCLUDED.confidence, typed = EXCLUDED.typed;
245 
246-- Typed edge from relationships: block
247INSERT INTO wiki_edges (source, target, relation, confidence, typed)
248VALUES ('concepts/transformers', 'concepts/lstm', 'contradicts', 'EXTRACTED', true)
249ON CONFLICT (source, target, relation) DO UPDATE SET confidence = EXCLUDED.confidence, typed = EXCLUDED.typed;
250```
251 
252Write one `INSERT ... ON CONFLICT (id) DO UPDATE` statement per page (values escaped: single quotes doubled, `tags` serialized as a JSON array literal cast to `jsonb`), then one `INSERT ... ON CONFLICT (source, target, relation) DO UPDATE` per edge. `relation` stays lowercase here (unlike the uppercased Cypher relationship label) since it's a plain column value, not a schema identifier — this keeps it directly filterable with `WHERE relation = 'contradicts'` or joinable without case-folding. `typed` is `true` only for edges promoted by a `relationships:` frontmatter entry; plain wikilinks stay `false`.
253 
254Skip pages whose `id` collides only after the `ON CONFLICT` clause fires from a prior run — do not attempt to deduplicate synthetic multi-edges (e.g. same source/target with both a `wikilink` and a typed relation) since the composite primary key `(source, target, relation)` already keeps them as distinct rows, matching the "typed version wins" merge behavior of `graph.json`/`graph.graphml` at the query layer (`SELECT * FROM wiki_edges WHERE source=$1 AND target=$2 ORDER BY typed DESC LIMIT 1`).
255

258### 3e. `graph.html`
259 
260A self-contained interactive visualization using the vis.js CDN (no local dependencies). The user opens this file in any browser — no server needed.
261 
262Build the HTML file by:
263 
2641. Generating a JSON array of node objects for vis.js:
265```js
266{id: "concepts/transformers", label: "Transformer Architecture", color: {background: "#4E79A7"}, size: <degree * 3 + 8>, title: "concepts | #ml #architecture", community: 0}
267```
268- Color by community (cycle through: `#4E79A7`, `#F28E2B`, `#E15759`, `#76B7B2`, `#59A14F`, `#EDC948`, `#B07AA1`, `#FF9DA7`, `#9C755F`, `#BAB0AC`)
269- Size by degree (incoming + outgoing link count): `size = degree * 3 + 8`, capped at 60
270- `title` = tooltip text shown on hover: category, tags, summary (if available)
271 
2722. Generating a JSON array of edge objects for vis.js:
273```js
274// Untyped wikilink
275{from: "concepts/transformers", to: "entities/vaswani", dashes: false, width: 1, color: {color: "#666", opacity: 0.6}, title: "wikilink"}
276// Typed edge
277{from: "concepts/transformers", to: "concepts/lstm", dashes: false, width: 2, color: {color: "#E15759", opacity: 0.8}, label: "contradicts", font: {size: 9, color: "#ccc"}, title: "contradicts"}
278```
279- `dashes: true` for INFERRED edges
280- `dashes: [4,8]` for AMBIGUOUS edges
281- **Typed edges** (`typed: true`): set `width: 2`, add a `label` field showing the type, and apply a type-specific color:
282 
283| Type | Edge color |
284|---|---|
285| `extends` | `#59A14F` (green) |
286| `implements` | `#4E79A7` (blue) |
287| `contradicts` | `#E15759` (red) |
288| `derived_from` | `#F28E2B` (orange) |
289| `uses` | `#76B7B2` (teal) |
290| `replaces` | `#B07AA1` (purple) |
291| `related_to` | `#BAB0AC` (grey — same as untyped) |
292 
293Untyped `wikilink` edges keep the existing `#666` grey color and no label.

363---
364 
365## Step 3.5: OKF Bundle Export (optional)
366 
367Run this step **only** when the user asks for OKF / a markdown bundle (phrases like "export to OKF", "OKF bundle", "open knowledge format", "export as markdown bundle"). It is additive — the five graph files above are always produced; this writes an extra full-fidelity markdown bundle.
368 
369The five graph files are a *lossy* projection (graph skeleton only). An **OKF bundle is the actual page bodies**, so an export→`wiki-import` round-trip through OKF preserves full content, and the bundle drops straight into MkDocs, Notion, Hugo, GitHub's renderer, or any [Open Knowledge Format](https://github.com/GoogleCloudPlatform/knowledge-catalog/blob/main/okf/SPEC.md) consumer.
370 
371### Canonical frontmatter mapping (obsidian-wiki ⇄ OKF)
372 
373This table is the single source of truth for the mapping; `wiki-import` references it for the reverse direction.
374 
375| OKF key | ← export from | → import to | Notes |
376|---------------|-------------------------|--------------------------|-------|
377| `type` (required) | `category`, title-cased | `category` (lower-cased) | `concepts`→`Concept`, `entities`→`Entity`, `skills`→`Skill`, `references`→`Reference`, `synthesis`→`Synthesis`, `projects`→`Project`, `journal`→`Journal`. OKF requires `type`; consumers tolerate any string. |
378| `title` | `title` | `title` | Verbatim. |
379| `description` | `summary` | `summary` | Our one-line `summary:` is exactly OKF's `description` (used in `index.md` entries). |
380| `tags` | `tags` | `tags` | Verbatim list. `visibility/*` system tags pass through unchanged. |
381| `generated` | `updated` → `generated.at`; `by` is the producer | `updated` ← `generated.at` | Write `generated: { by: obsidian-wiki/<version>, at: <datetime> }`, taking `<version>` from `obsidian-wiki --version` (plain `obsidian-wiki` if the CLI isn't installed). OKF §5 requires every timestamp to be a datetime with an explicit offset, so a date-only `updated: 2026-04-12` becomes `2026-04-12T00:00:00Z`. Replaces v0.1's `timestamp`, which is no longer written. |
382| `sources` | `sources` (list of strings) | `sources` (list of strings) | OKF `sources` is a list of objects with a required `resource`, so each native string becomes `- resource: <string>`. Opaque strings like `conversation:2026-04-12` are valid: §5.1 allows scope descriptors a consumer can't follow. Emit nothing else per entry, so import recovers the exact strings. |
383| `status` | `lifecycle` | — (native `lifecycle` is preserved) | `draft` → `draft`; `reviewed`, `verified`, `disputed` → `stable`; `archived` → `deprecated`. Omit `status` when `lifecycle` is absent (absent means `stable` in OKF). |
384| `verified` | `_meta/trust-ledger.json` entry for the page | — (preserved verbatim) | Only when the page has a ledger entry: `verified: { by: human:vault-owner, at: <entry reviewed_at> }`. `trust-record` only writes entries a human approved with `--approved`, so the `human:` actor is accurate and gives the page OKF's *human-reviewed* tier (§5.3). Never derive `verified` from `lifecycle` alone. |
385| `resource` | first `sources:` entry **iff** it is an `http(s)://` URL | — | Optional; omit when no source URL. Most pages describe abstract knowledge and have none. |
386| *(extensions)* | `category`, `created`, `updated`, `relationships`, `lifecycle`, `lifecycle_changed`, `tier`, `base_confidence`, … | preserved verbatim | OKF §4.1 requires consumers to preserve unknown keys. **Writing our native keys as OKF extension frontmatter is what makes the round-trip lossless** — on import, preserved `category`/`created`/`updated`/`lifecycle` are preferred over re-deriving from `type`/`generated`/`status`. (`updated` rides along because `generated.at` must be a full datetime, so a date-only `updated` would otherwise come back as midnight UTC.) `sources` is *not* an extension any more: it's a spec field (row above). |

390Reuse the node list from Step 1 (with any active project/visibility filters already applied). Write a directory tree under `wiki-export/okf/`:
391 
3921. **One file per in-scope page.** For each page, parse its frontmatter, apply the mapping table above to build the OKF frontmatter (required `type` first, then `title`, `description`, `tags`, `generated`, `status`, `verified`, `sources`, optional `resource`, then the preserved extension keys), transform the body links (below), and write to `wiki-export/okf/<category>/<slug>.md` — same relative path the page has in the vault.
393 
3942. **Body link transform** (`[[wikilinks]]` → standard markdown links):
395 - `[[concepts/transformers]]` → `[<target title>](<file-relative path>.md)`, e.g. from `entities/foo.md` a link to `concepts/transformers` becomes `[Transformer Architecture](../concepts/transformers.md)`. Link text = the target page's `title` (fall back to the target id if unknown).
396 - `[[target|display]]` → `[display](<rel path>.md)`.
397 - Use **file-relative** paths (`../concepts/x.md`), **never** `/`-absolute — `/`-rooted links break GitHub rendering. (This matches knowledge-catalog's own production agent.)
398 - Compute that relative path from the **target file path**, not the bare page id: normalize the wikilink target to its page id, append `.md`, then compute `relpath(<target-file>, <source-file-dir>)`. Never call `relpath()` on the id before adding `.md`.
399 - This is required for the common "folder note" layout where a page id exists both as a file and as a directory prefix, e.g. `projects/social-twitter.md` plus `projects/social-twitter/...`. From `projects/social-twitter/concepts/mem0-memory-analysis.md`, a link to `[[projects/social-twitter]]` must export to `../../social-twitter.md`, not `...md`.
400 - Resolve link targets with the same normalization used in Step 1 (lowercase, spaces→hyphens, strip `.md`). Handle unresolved targets by form, so forward-references survive the round-trip:
401 - **Resolves to an in-scope page** → relative markdown link to it.
402 - **Path-form target** (contains a `/`, e.g. `[[concepts/attention-mechanism]]`) with **no page yet**, and not excluded by an active filter → still emit the relative markdown link. OKF §11 forbids rejecting a bundle over a broken cross-link, and keeping the link makes the user's forward-references lossless on re-import. (Verified on st3ve: dropping these silently deleted real `[[wikilinks]]`.)
403 - **Excluded by an active project/visibility filter** → plain text. Do not emit a path pointing into filtered-out content.
404 - **Bare-title target** with no match (e.g. `[[tractorex]]` when no such page exists in scope) → plain text; there is no reliable path to write.
405 - Leave existing external `http(s)://` links and `# Citations` sections untouched.
406 
4073. **Generate `index.md` files** (OKF §8 progressive disclosure; these contain no per-entry frontmatter):
408 - Bundle root `wiki-export/okf/index.md` — a `# Subdirectories` section listing each category folder: `* [<category>](<category>/index.md) - <one-line description of the category>`. This is the **only** index permitted frontmatter: add a single key `okf_version: "0.2"` (OKF §8, §12).
409 - One `index.md` per category folder listing its pages: `* [<title>](<slug>.md) - <description from the page's summary>`.
410 
4114. **Write `log.md`** from the vault root's `log.md`, reshaped to OKF §9, which requires `## YYYY-MM-DD` date headings, newest first. Our log is a flat, oldest-first list of `- [<timestamp>] VERB key=value …` lines, so: start with `# Wiki Update Log`; group lines by the date part of `<timestamp>`; emit groups newest first under `## <date>`; render each line as `* **<Verb>**: <rest of line>`, with the verb title-cased (`INGEST` → `Ingest`). Keep lines that don't match the pattern under the date of the line above them, verbatim after `* `. `wiki-import` ignores `log.md`, so this costs nothing on the round-trip.
412 
4135. **Filters.** Honor the same project/visibility filters as the graph export — filtered pages are omitted from the bundle and their inbound links degrade to plain text per step 2.
414 
415Excluded from the bundle (same as the graph export): `_archives/`, `_raw/`, `_readouts/`, `.obsidian/`, `_insights.md`, `_meta/*.base`, and the vault root `index.md` (regenerated above).
416 
417---
418 
419## Step 4: Print Summary
420 
421```
422Wiki export complete → wiki-export/
423 graph.json — N nodes, M edges (NetworkX node_link format)
424 graph.graphml — N nodes, M edges (Gephi / yEd / Cytoscape)
425 cypher.txt — N MERGE nodes + M MERGE relationships (Neo4j)
426 postgres.sql — N upsert rows (wiki_pages) + M upsert rows (wiki_edges) (any Postgres)
427 graph.html — interactive browser visualization (open in any browser)
428```
429 
430Append this line only when the OKF bundle was produced (Step 3.5):
431```
432 okf/ — OKF v0.2 markdown bundle (N pages, lossless; import via wiki-import)
433```
434 
435Append filter notes when active:
436```
437 (filtered: project:prismor — 19 of 67 pages)
438 (filtered: X of Y pages excluded — visibility/internal, visibility/pii)
439```
440Only include lines for filters that were actually applied.
441 
442## Notes
443 
444- **Re-running is safe** — all output files (and the `okf/` bundle) are overwritten on each run
445- **Broken wikilinks are skipped** — only edges to pages that exist in the vault are exported; in the OKF bundle, a wikilink to a missing/filtered page degrades to plain text
446- **OKF is the lossless format** — `graph.json` reconstructs only stubs on import, while the `okf/` bundle preserves full page bodies. Use OKF for vault-to-vault transfer and external markdown tools (MkDocs, Notion, GitHub); use the graph files for analysis tools (Gephi, Neo4j)
447- **The `wiki-export/` directory should be gitignored** if the vault is version-controlled — these are derived artifacts
448- **`graph.json` is the primary format** — the others are derived from it. If a future tool supports graph queries natively, point it at `graph.json`
