The RING database is also available as an RDF* store.

1) On each service page, there is a link to its RDF representation. The RDF vocabulary that has been chosen to describe services is DOAP ("Description of a Project"), which was conceived to describe software projects. Some DOAP properties are speciifc to software tools more than to services, but it seems the most suitable vocabulary, among those that are widely known and adopted, for the content of the RING. 
The URI for each service is built as follows: RING-domain/node/service-ID/rdf.
For example, the URI of the AgriFeeds service in this RDF store is:
http://ring.ciard.net/node/2417/rdf

2) The whole RDF store is accessible through a SPARQL engine, which means that any system can run remote queries and get the resulting triples.
The endpoint of the SPARQL engine is:
http://ring.ciard.net/service/sparql
The vocabularies used in the RDF store are:
RDF: http://www.w3.org/1999/02/22-rdf-syntax-ns#
RDFS: http://www.w3.org/2000/01/rdf-schema#
FOAF: http://xmlns.com/foaf/0.1/
DOAP: http://usefulinc.com/ns/doap#

Below you can find some examples of SPARQL queries with a basic tabular representation of the resulting triples.
