Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"sdc-codata-cdif-projection-sdccdif","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

CDIF (CODATA Cross-Domain Interoperability Framework) descriptions of published Semantic Data Charter models: Discovery, Data Description with every variable, Codelists and the sentinel domain for the sixteen exceptional values, as JSON-LD, the model's schema cited by URL and SHA-256. One tool, write_cdif, over the same function the CLI calls; validated in the package's CI with CDIF's own framing, JSON Schema and SHACL checks. Read-only apart from the document it returns; no account; the catalog host is fixed at start and no tool takes a URL. Self-hosted MCP server over stdio: pip install sdccdif, then run 'sdccdif mcp' (or uvx sdccdif mcp).
Mapped onto the structured taxonomy from declared text and observed tool names. Confidence shown for derived entries.
Every source is kept verbatim. Field changes are logged as events.
