Dear PSC,
Data Catalog Vocabulary services [1] in GeoNetwork opensource increase
discoverability and enable applications easily to consume metadata.
The output format produced by the services are based on RDF vocabulary
(DCAT, SKOS and FOAF).
Two types of services are created:
* Metadata service to access to one metadata record
* Search service to search the catalogue and retrieve a set of metadata
The Data Catalog Vocabulary services could be used by Semantic web
tools to harvest, search (eg. using SPARQL) and link catalogue content
with other interlinked resources (See [2] for examples).
A semantic portal sitemap is created in order to be able to harvest
the catalogue.
Looking forward to your votes.
Regards
Francois

Dear François,
This is a great next step for GeoNetwork I think. Curious to see what the uptake of such services will bring to GeoNetwork users.
+1 from me.
Cheers,
Jeroen
