FIT – Metrics for LOD KOS (as value vocabularies)_
| [The vocabulary is...] | [The vocabulary...] | [The vocabulary...] |
The vocabulary is delivered in consumable formats Provided SPARQL endpoints are operational Dataset properties and structures are informed effectively Services are user-friendly, making vocabulary contents reachable | Exposed through terminology services Used by data providers
as a primary value vocabulary in semantic enrichment Mapped with other KOS vocabularies Showed/discussed at professional conferences and publications | Allows special KOS products to be derived from the original data The user is given autonomy to determine what structure and information is desired and can be reproduced from the vocabulary Enables extensibility to fit diverse needs Supports innovative and transformative uses beyond normal “value vocabularies” |
