API- getting back URIs of ontologies with incoming links

[gatemezing]

Some users need to make a call via the API to retrieve the URIs of all the ontologies that use a giving vocab.
Of course a SPARQL query, like this one for PROV-O [http://goo.gl/XzzWpr ] can answer. However, could it be implemented natively within the API?

This is always possible, the question is: how many users/software will use that API?
This is a custom query that indeed can be already performed using SPARQL.

👍 Yeah.. At least I have one use case from Oxford.
One could argue that our API should provide access to native relationships between vocabularies, that is the "core of LOV" with the voaf vocabulary, such as "inlink" or "outlink" to/from a vocabulary.
