Ontaria is a searchable and browsable directory of semantic web data. Our focus is RDF vocabularies with OWL ontologies, but all the RDF data we index is visible. The site is primarily intended for people creating RDF content who want to better understand which vocabularies are available and how they are being used. Beyond this, Ontaria may be useful for finding and exploring arbitrary RDF content.
Like most web directories and search engines, Ontaria gathers its information from other web sites. To request Ontaria examine a specific site, use the add a site page. To request exclusion, use the robot exclusion protocol, robot name "ontaria".
Ontaria is a project of W3C Semantic Web Advanced Development, funded by DARPA's DAML program. (Principal Investigator: Tim Berners-Lee. Lead Developer: Sandro Hawke).
We expect to announce this site and call for brave new users the week of May 24th. If you've found it early, you're welcome to poke around, but please wear your hard hat.
