A proposal before the World Wide Web Consortium (W3C) would dramatically improve SPARQL, the query technology for the Semantic Web, for application development. SPARQL Query 1.1 is part of a proposal submitted by W3C in early July that schedules a new version of SPARQL for release in the fall of 2010.

"Some of the new features try to make the development of applications easier, performing standard operations on the query processor side that applications have to do repeatedly today," says W3C Semantic Web Activity lead Ivan Herman. "Examples are calculating the minimum or the maximum of returned numerical values, combining returned values through standard operations like numerical multiplications, etc."

The proposal also calls for the ability to nest queries within queries to reduce communication and programming overhead, as well as SPARQL implementations with special functions for local use. "In the new environment, it will be possible to describe these features through standard means and client programs will be able to automatically find and interpret these descriptions and adapt their behavior accordingly," Herman says.
