SPARQL queries on workspace/temporal data

[DiegoVinasco]

• What is the cost of a UNION in graph construction?
• What are the FAQ queries we want to address?
  • Check GeoTriples authors, who may have already determined these questions (GIS questions)
  • We also should look at potential 3D/topology questions
• What are the execution times of graph constructions and queries on these questions?

Also what are some general statistical information about our data:

• number of triples per dataset
• number of triples per XML tag
• number of classes, properties, datatypes
• data volume (in KB/MB)
