DAML+OIL for Application Developers - slide "Query Example: RDQL"

RDF Data Query Language (RDQL) is implemented by the com.hp.hpl.jena.rdf.query package in Jena
- it uses an SQL-like syntax to perform exact matches on triples

example: return any versionInfo information in the model


SELECT ?subject, ?version
WHERE (?subject, <daml:versionInfo>, ?version)
USING daml FOR <http://www.daml.org/2000/12/daml+oil#>

which returns sets of matching variable bindings
