Epic: Obsidian & Logseq community integration (vault parser + plugins + launch)

[AlexMikhalev]

Summary

Integrate terraphim with the Obsidian (~50k stars) and Logseq (~35k stars) PKM communities through parser extensions, community plugins, and a coordinated open-source launch.

Terraphim's KG parser already uses Logseq's synonyms:: property syntax -- which is the same syntax as Obsidian's Dataview inline fields. This gives us a bridge to both communities without inventing a new format.

Issues

Parser & Core

• Obsidian format parser: aliases, wikilinks, and tags extraction #604 Obsidian format parser (aliases, wikilinks, tags) -- ~4h
• Concept relationship layer: wikilink edges in rolegraph #605 Concept relationship layer (wikilink edges in rolegraph) -- ~1d

Plugins

• Obsidian community plugin: WASM-powered semantic search #606 Obsidian community plugin (WASM terraphim in Electron) -- ~2d
• Logseq community plugin: WASM-powered semantic search #607 Logseq community plugin (WASM terraphim slash commands) -- ~1d

Community Launch

• Community launch: blog posts, HN/Reddit announcements, positioning #608 Launch positioning, blog posts, HN/Reddit/forum announcements

Positioning

"Deterministic semantic search for your vault -- 15 MB RAM, zero LLM, zero cloud."

Unique differentiators vs existing solutions:

• vs Obsidian built-in search: synonym expansion, concept matching, sub-200ms
• vs Smart Connections plugin: no API key, no embeddings model, deterministic, private
• vs Logseq built-in search: full-text + semantic concept matching via Aho-Corasick
• vs any LLM-based solution: works offline, deterministic results, zero cost per query

The Bridge

Logseq property synonyms:: foo, bar = Obsidian Dataview inline field synonyms:: foo, bar

One syntax, two communities. Extend to also parse Obsidian-native aliases: from YAML frontmatter, [[wikilinks]] as concept edges, and #tags as categories.

Launch Targets

• HN Show HN (Tue-Thu 8-10 AM ET)
• Reddit: r/ObsidianMD (300k), r/logseq (30k), r/PKMS (25k), r/rust (300k), r/selfhosted (400k)
• Obsidian community forum + Logseq Discord
• Medium Obsidian Observer publication
• 3-min demo video

Exit Criteria

• Obsidian plugin published in community registry
• Logseq plugin published in marketplace
• Blog post + HN/Reddit announcement
• Parser handles all three formats: terraphim, logseq, obsidian
• 500+ Obsidian installs, 100+ Logseq installs, +200 GitHub stars (first month)
