The SPARQL query language for RDF is designed to meet the use cases and requirements identified by the RDF Data Access Working Group in RDF Data Access Use Cases and Requirements. sparkle-g (SPARQL Grammar) is a SPARQL ANTLR v3 cross-platform grammar.

2009-11-28 2.0 Release is out

Switched to Apache License 2.0 and proper Maven 2 build, check out the 2.0 site

2011-12-25 3.2 Release is out

The sparkle-g project has released a pretty printer and syntactic validator for the SPARQL 1.1 Query and Update Language . The pretty printer and syntactic validator is based on the ANTLR framework for constructing recognizers, interpreters, compilers, and translators. The generation of the formatted output text relies on the StringTemplate template engine. ANTLR and StringTemplate have both been designed and crafted by Terence Parr, a professor of computer science at the University of San Francisco.

Support of Maven 3 build, check out the 3.2 site

2012-01-04 3.3.1 Release is out

• Several fixes with regards to rewriting and group template rules mostly concerning update rules.

• Split of Sparql.g (combined lexer and parser grammar) in two distinct files SparlLexer.g (lexer grammar) and SparqlParser.g (parser grammar) for SparqlPrettyPrinter. The generated files remain the same! This might ease the construction of composite grammars (see: http://www.antlr.org/wiki/display/ANTLR3/Composite+Grammars)

• Added queries from http://www.w3.org/TR/sparql11-update/#updateLanguage as testcases.
