Standards Index

The bedrock list. Every entry below is a standard, specification, methodology, or canonical reference the untool.ai platform anchors to — not "inspired by," but normatively cited in an Architecture Decision Record (ADR), a contract, or a foundational doc.

This page exists so that a reviewer — an architect, a security lead, an auditor, or a compliance reader — can scan a single index and verify that the platform is standing on bedrock rather than inventing. Wherever possible each row links to the ADR or doc that adopts the standard, the standards body that publishes it, and the exact version we anchor to. Versions are pinned: this page does not say "latest" — it says the version our generators, contracts, and conformance tests target. When we deviate from a standard (e.g. a BFO-lite projection of our UFO model), the deviation itself is recorded in an ADR and noted in the "Used in" column.

The catalog is grouped into eleven layers. The first ten are normative standards; the eleventh is a curated bibliography of the books that shaped the methodology. Together they form the platform's standards spine — the answer to "where does this come from?"


1. Foundational ontology & knowledge representation

The platform's conceptual core is a UFO/OntoUML model that projects to a BFO/CCO interop view. Both lineages are recorded so that BFO/OBO-aligned consumers and UFO/OntoUML-aligned consumers can both ingest the model without translation loss.

Notes on usage

  • "Used in" links point to internal ADRs and docs. When a row references an ADR that has not yet been numbered (drafts), it is listed by topic; the merge-time ADR number assigner (docs/decisions/README.md) will rewrite the reference once the ADR lands.
  • Where a row pins a draft IETF or W3C spec (e.g. OAuth 2.1), the platform's contract tests target the current draft head as of the relevant ADR date, with a follow-up tracking issue to re-pin when the document advances to RFC.
  • The bibliography is intentionally short of generic textbooks: only books actively cited as rationale appear. If a book is referenced in a future ADR it should be added here in the same pass — this page is the single index for "where does this come from?".
