Please accept our apologies for any cross-postings ================================================== Dear all, We are pleased to announce the availability of the RQL Interpreter, under open-source license. The RDF Query Language Interpreter (RQL), v1.0, a Declarative Language for uniformly querying RDF schemas and resource descriptions. You can download it from: http://139.91.183.30:9090/RDF/RQL/ RQL v1.0 main features ================================================== Supports: - XML Schema data types (for filtering literal values) - grouping primitives (for constructing nested XML results) - aggregate functions (for extracting statistics) - recursive traversal of class and property hierarchies (for advanced matchmaking) Pushes as much as possible query evaluation to the underlying DBMS - Benefit from robust SQL3 query engines - Extensive use of DB indices Provides generic RDF/XML result form - XSL/XSL processing for customized rendering Easy to couple with commercial ORDBMSs - RDF Querying APIs (SQL3/C++ functions) Easy to integrate with Web Application Servers - C++ or Java drivers to RQL servers Easy to learn and use - One day training We are looking forward to receiving your comments and suggestions. Best regards Grigoris Karvounarakis
