wik.jp Persistent Identifier Policy (v1.1, 2026-07)

1. Purpose. wik.jp provides permanent, resolvable URIs for Japan-related
   Linked Open Data vocabularies and datasets.
2. Stability. Once minted, a URI under wik.jp is never reassigned to a
   different concept. Deprecated concepts remain resolvable and are marked
   with owl:deprecated / skos:historyNote rather than removed.
3. Independence. The domain is held by an individual maintainer,
   independently of any single company. Vocabulary publishers (e.g.
   Terra-International OÜ) may change, merge, or transfer their assets without
   affecting URI resolution.
4. Continuity. The domain is on multi-year auto-renewal. All redirect
   rules are maintained in a public Git repository and deployed via CI,
   so the service can be reconstructed from public sources by a successor.
5. Succession. In the event the maintainer can no longer operate the
   service, stewardship is offered first to the vocabulary publishers,
   then to the Japanese LOD community (e.g. LOD Challenge Japan
   community), with DNS transfer.
6. Contact. See https://wik.jp/ for current contact details.
