<Note>The Knowledge Base is in **beta**.</Note>

The **Knowledge Base** renders the published ontology as a human- and agent-readable wiki. It
runs automatically on a configurable cadence — for example daily, or every few hours —
compiling all of your organization's ontology resources into a single maintained knowledge
bundle.

The Knowledge Base is a **rendering** of the ontology, not an independent source of truth. It
does not author knowledge of its own; everything it contains is derived from published
primitives. Each scheduled run regenerates and gardens the bundle so that it reflects the
current state of the ontology, including any updates the
[Ontology Agent](/agentic/ontology-agent) has published since the previous run.

## Output format

The Knowledge Base emits its wiki in the **Open Knowledge Format** (OKF), an open,
vendor-neutral specification published by Google Cloud in June 2026 for representing knowledge
as a directory of markdown files with YAML frontmatter.

OKF is deliberately minimal:

- Each concept — a thing type, a metric, a process — is a single markdown file.
- Files interlink with ordinary markdown links, forming a navigable graph.
- Frontmatter carries metadata, with `type` as the only required field.
- By convention, an `index.md` enumerates the contents of a directory to support progressive
  disclosure, and a `log.md` records changes over time as a changelog that travels with the
  knowledge — a natural destination for the updates surfaced by drift detection.

Because the output is plain markdown and YAML, it:

- requires no runtime or SDK to read,
- renders directly in any tool that displays markdown,
- is diffable in version control, and
- can be consumed by any agent or system that understands the format.

Choosing OKF as the output format keeps your knowledge **portable**: structured enough to be
useful, open enough to avoid lock-in.

## Relationship to the Ontology Agent

The [Ontology Agent](/agentic/ontology-agent) maintains the structured model; the Knowledge
Base presents it. The two are not separate agents but two faces of the same maintained
knowledge — one optimized for systems and modeling, the other for reading and
interoperability.
