OKF Wiki

An Obsidian-backed, LLM-maintained personal knowledge base that follows Google's Open Knowledge Format.

Clone this repo, open a bundle in Obsidian, point your LLM agent at AGENT.md, and start building a compounding knowledge base today.

What is this?

Most people's experience with LLMs and documents looks like RAG: upload files, the LLM retrieves chunks at query time, and generates an answer. There's no accumulation. Nothing is built up.

OKF Wiki is different. Instead of retrieving from raw documents at query time, your LLM agent incrementally builds and maintains a persistent wiki — a structured, interlinked collection of markdown files that sits between you and your sources. When you add a new source, the agent:

1. Reads it and extracts key information
2. Creates a structured summary page
3. Updates entity and concept pages across the wiki
4. Notes where new data contradicts old claims
5. Maintains cross-references so everything is connected
6. Keeps an index and log so you can find everything later

The knowledge is compiled once and then kept current, not re-derived on every query. The wiki keeps getting richer with every source you add.

You never write the wiki yourself — the LLM does all the summarizing, cross-referencing, filing, and bookkeeping. You curate sources, ask questions, and think about what it all means.

Read llm-wiki.md for the full vision.

Why OKF?

Open Knowledge Format (OKF) is Google's open standard for representing knowledge as a directory of markdown files with YAML frontmatter. It's designed to be:

• Readable by humans without tooling (cat a file, you can read it)
• Parseable by agents without bespoke SDKs
• Diffable in version control (git diff works naturally)
• Portable across tools, organizations, and time

No schema registry, no central authority, no required tooling. If you can git clone a repo, you can use OKF.

This repository is a reference implementation: an OKF-compliant Obsidian vault purpose-built for the llm-wiki pattern. See SPEC.md for the full specification.

Key Features

• OKF-compliant — Every page has structured YAML frontmatter with type, title, tags, and timestamps. Cross-links use bundle-relative paths.
• Obsidian-native — Each bundle is a self-contained Obsidian vault. Open it and you get graph view, backlinks, search, and all Obsidian features for free.
• Agent-first design — AGENT.md tells any LLM agent exactly how to operate: ingest sources, answer queries, lint the wiki, maintain the index.
• Multi-bundle — The bundles/ directory can hold multiple independent knowledge bases, each with its own structure and Obsidian configuration.
• Templates included — Obsidian templates for source summaries, concept pages, and log entries so the agent (or you) can create pages with pre-populated OKF frontmatter.
• Git-friendly — It's just a directory of markdown files. Version history, branching, and collaboration come for free.
