Independent This document defines the "knowledge-linkset" well-known URI, at which a web origin publishes one link set describing the knowledge artefacts it makes available: graph serializations, a JSON-LD context, an agent-facing text file, a chunk export, a change ledger, and related resources. Each artefact link may carry a SHA-256 digest, expressed with the syntax of HTTP digest fields, so that a client can check that a retrieved artefact is the one the publisher described. A profile URI identifies the conventions the link set follows. The mechanism defines no new media type and no new link relation type: a page points at the resource with the existing "describedby" relation. The profile URI is registered in the IANA "Profile URIs" registry. This document requests no IANA action.
