RDF Query Language (RQL)
Declarative language (like ODMG OQL) for conceptual browsing & querying of voluminous RDF Description Bases
- Easy navigation and resource discovery (using few query terms)
- Task-specific personalization of RDF description bases (views)
- Seamless querying of RDF schemas and resource descriptions
- Flexible export facilities of RDF metadata (restructuring)
RQL fully supports:
- XML Schema data types (for filtering literal values)
- grouping primitives (for constructing complex XML results)
- aggregate functions (for extracting statistics)
- recursive traversal of class and property hierarchies (for matchmaking)
Implementation:
- C++ development (GCC 2.95.1) on top of an ORDBMS (Unix, Linux)
- Client/Server architecture (XDR-based)
