All,

As the answer of the question in the subject of this email doesn't have an
easy answer via the current API, here is a suggestion (originally by Egon)
how to extend the API :

1) Each service implements  /{service}/sparqlendpoint

e.g. /compound/sparqlendpoint  , /model/sparqlendpoint , etc.

2) The /{service}/sparqlendpoint  returns on GET zero, one or mode URLs of
ontology services, using text/uri-list   mime type;

3) Adding, updating and deleting entries is done via POST , PUT and DELETE
to /{service}/sparqlendpoint
(whether it will use www-form or text/uri-list as content-type is to be
specified )

Similar approach might be adopted for returning URLs of AA services , e.g.
/{service}/auth.

Any feedback is welcome.

Best regards,
Nina
