An RDF vocabulary for representing web services and web-based APIs, from RESTful APIs (including RSS feeds, OAI-PMH endpoints, SPARQL endpoints etc.) to SOAP web services to XML/RPC web services etc.
The agINFRA Consortium doesn’t feel as the best positioned actor to create an authoritative vocabulary for this, but while waiting until a better positioned organization does it in a better way, we acted as a subsidiary authority and created one for our needs.
