Draft 0.3 · Release 01M6BSMCAQ · Attribution required

The knowledge base models were built for.

Flat, dated, evidenced claims about organizations, their domains and infrastructure, their leadership and publications, and the fingerprints that tie them together. One record, five renderings, every claim a revision you can cite.

Try wikidata.org, cert:14a7accb60f4, Jimmy Wales, a shared lookup, or an entity with no record yet.

Every claim is dated.

Every claim cites a capture.

Absence is a scoped fact.

Nothing is too small to record.

Bitemporal by default. A claim carries when it held in the world and when we learned it, with partial dates as intervals. Ask for the record as of any date, definite or possible, and stale facts stop masquerading as current.

Evidence, not references. Each claim points at a captured source with a content hash, a verbatim quote that must occur in the capture, the source family, and the rights it was captured under. Sources rot; captures do not.

Negative knowledge is stored, with its scope. "No LEI was found in GLEIF as of today" is a claim with evidence of what was checked, so a model can learn to abstain without learning a falsehood.

No notability gate. Organizations, domains, tracker ids and certificates get records the moment anyone asserts a claim. Salience is a tier, not a door, and every edit is a revision with its own citation.
