rdbms.RdfSchemaRepository should optimize DirectXYZ path expressions

Created: 13/Feb/04 03:21 PM   Updated: 25/Mar/04 02:58 PM
Component/s: RDBMS Sail
Affects Version/s: 1.0
Fix Version/s: 1.0


 Description   
The optimizeQuery(...) method in rdbms.RdfSource currently only translates TriplePattern objects to an integrated SQL query. rdbms.RdfSchemaSource should override this behaviour and handle objects of type DirectSubClassOf, DirectSubPropertyOf and DirectType and extend any generated SQL query with these paths. This will speed up query performance for these kinds of queries considerably.
