http://www.openlinksw.com/blog/kidehen@openlinksw.com/blog/?id=947 Swoogle knows how Semantic Web ontologies are used: " The Dublin Core Metadata Initiative is updating the RDF expression of DC and might add range restrictions to some properties. Mikael Nilsson wondered if we would use the Swoogle Semantic Web search engine to see what types of values are being used with DC properties. This kind of query is just the ticket for Swoogle. Well, almost. The current web-based interface supports a limited number of query types. Many more can be asked if you use SQL directly to query Swoogle’s underlying databases. We don’t want to provide a direct SQL query service over the main Swoogle database because it’s easy to ask a query that will take a looooooong time to answer and some could even crash the database server. We are planning to put up a second server with a copy of the database and we give Swoogle Power Users (SPUs) access to it. We ran a simple SQL query to generate some initial data for Mikael showing fall of the DC properties. For each one, we list all of the ranges that values were drawn from and the number of separate documents and triples for each combination. For example Property Range Documents Triples dc:creater rdfs:Literal 32 648 dc:creator rdfs:Literal 234655 2477665 dc:creator wn:Person 2714 1138250 dc:creator cc:Agent 4090 6359 dc:creator foaf:Person 2281 5969 dc:creator foaf:Agent 1723 3234 Notice that the first property in this partial table is an obvious typo. You can see the complete table as pdf file or as an excel spreadsheet.
