SRV-O: Service Extension: Description back to ToC

SRV-O is an extension of the SKG-IF Ontology (SKG-O) that introduces entities necessary to model Service-type objects used to process data in various use-cases, as well as their relationships with well-established entities in the SKG-IF data model. This extension is developed in the context of the OSTrails project.

Object Properties

bido:holdsBibliometricDataInTime (SKG-IF labels: topics)op back to ToC or Object Property ToC

IRI: http://purl.org/spar/bido/holdsBibliometricDataInTime

The core SKG-IF ontology restricts this property's domain to fabio:Work (research products). This entry extends effective use to srv:Service, following the same pragmatic usage already present in all 120+ ext-srv example files. NOTE: The full BIDO structure (bido:holdsBibliometricDataInTime → bido:BibliometricDataInTime → bido:withBibliometricData → fabio:SubjectTerm) is overkill for Service topic classification. The bido:BibliometricDataInTime wrapper exists to carry provenance (trust scores from multiple inference systems) and temporal tracking — neither of which applies to services, where topics are asserted directly by the service maintainer. Kept for consistency with the core inter-entity relation pattern between entities and Topic entities (both must resolve via the same local_identifier). TODO: Propose to the core team (skg-if/data-model) that bido:holdsBibliometricDataInTime be broadened to a general cross-entity alias not restricted to fabio:Work — topics are equally applicable to Services, Venues, Data Sources, etc. Consider also whether a simpler cross-entity topics relation (without the BIDO provenance wrapper) would better serve non-bibliometric entities.
