Enter SparQL query:

(Sample queries over rdf graph representation of the SIMILE Longwell project codebase)

Sample Query 1: (OnPath query)
# This query determines the dependencies of the class jena.rdfquery 
# It does so by computing the transitive closure of the the "uses"
# predicate from jena.rdfquery. It also returns the location (jar file) 
# for each result.

PREFIX gleen:<java:edu.washington.sig.gleen.>
PREFIX java:<http://simile.mit.edu/2004/09/ontologies/java#>

SELECT ?dependency ?location
FROM <http://sig.biostr.washington.edu/~detwiler/OntViews/GLEEN_demo/longwell-code.n3>
WHERE
{
   <urn:java:jena.rdfquery> gleen:OnPath ( "[java:uses]*" ?dependency ).
   OPTIONAL { ?dependency java:located ?location . } .
}
ORDER BY ?dependency


Sample Query 2: (Subgraph query over SIMILE Longwell codebase rdf graph)
# This query calculates the subgraph described by the set of paths 
# which start with jena.rdfquery and end at org.xml.sax.Locator and contain only  
# "uses" predicates. It returns the results as a new rdf graph.
