A persistent URI namespace at https://w3id.org/pkm with Linked Data resources on
Personal Knowledge Management (PKM) for the Knowledge System Architecture (KSA) project.
All identifiers in this namespace are w3id.org/pkm/... URIs. They are stable and
independent of where the site happens to be hosted — please cite them, not the
underlying host.

“Declared, empty” means the URI resolves and carries its metadata, but no terms have been minted yet. “Planned” means the page describes intent only.
Machine-readable descriptions of the namespace itself:
context.jsonld (JSON-LD context) and
void.ttl (VoID dataset description).
Vocabulary 0.1.11 — early draft, published for feedback. Terms are not yet stable and may change without notice until 1.0.0 is tagged.
Nothing is deleted outright: a retired URI keeps resolving, marked owl:deprecated
and pointed at its replacement with dcterms:isReplacedBy, so a link made today does
not rot. Comments and corrections are welcome — that is what this release is for.
See the changelog for what changed in each version and what counts as a breaking change.
