Bookmark / read-it-later ontology

version info: 0.1.0
comment: The RDF data model for bookmarks / read-it-later (a Linkding→Solid fork). Mints only book:Bookmark, book:archived and book:notes; reuses schema:url, schema:keywords (tags) and Dublin Core for the rest. book:Bookmark roots in core:InformationResource (the gUFO-rebased Solid Core).

Bookmark
type: Class
subclass of: InformationResource
comment: A saved bookmark / read-it-later entry: a stored reference to a web resource (schema:url) with a title, description, markdown notes, tags and an archived flag. Rooted in core:InformationResource (the saved thing is an information resource, not the act of bookmarking — see the skos:closeMatch to schema:BookmarkAction).

archived
type: DatatypeProperty
comment: Whether the bookmark is archived (Linkding's is_archived). An xsd:boolean; absent reads as false.
domain: Bookmark
range: boolean

notes
type: DatatypeProperty
comment: The user's free-text markdown notes on the bookmark (Linkding's notes). Distinct from the short dct:description blurb — notes is the longer markdown body.
domain: Bookmark
range: string
