Release Notes: This version completes support for SPARQL 1.0 by passing 100% of the approved tests. It adds full support for XSD date and makes XSD dateTime and XSD date equality and comparison work. The query engine was fixed to make limit and offset check work properly in a subquery, correctly handles errors during aggregation expression evaluation, and fixes blank node generation when made in a CONSTRUCT to match SPARQL. SPARQL 1.1 draft UUID() and STRUUID() support were added. RDQL support will be removed in the next release (0.9.30). Multiple other fixes and improvements were made.
Release Notes: Full support for SPARQL 1.1 draft STRBEFORE, STRAFTER, and REPLACE has been added. A new internal Mersenne Twister PRNG has been added with the choice adjustable by configure. The language name "sparql" is now SPARQL 1.1. The query result formats now all use W3C Format URIs as their primary URI. The configure check for ceil(), floor(), and round() has been improved to prevent GCC from optimizing the test away and getting the wrong answer. Several other fixes and improvements have been made.
Release Notes: SPARQL 1.1 query draft support was added for ABS(), CEIL(), FLOOR(), RAND(), ROUND(), TZ(), and BIND(expr AS ?var). SILENT with DROP and CLEAR was fixed. ENCODE_FOR_URI() was fixed not to preserve language and datatype of argument. GROUP BY was fixed to allow an optional AS ?var. An expression evaluation context class was added to store state for use with evaluating expressions. Triple-quoted literals over-quoting and their use with language and datatypes were fixed. Random seed initializing support was added. The query engine execution was fixed in several cases. rasqal_query_set_store_results() now actually works.
Release Notes: Parsing of SPARQL 1.1 Update draft INSERT and DELETE was fixed to to return sequences of triples. Cleanup of parsing state was improved when syntax errors happened due to disabled query language features. A few other bug fixes were made.
Release Notes: This version was changed to support only Raptor V2 (2.0.0+) and an ABI/API break was made to remove deprecated functions, types, and enums. It also added 7 SPARQL 1.1 editor's draft datetime and 9 string builtin functions with execution support. 4 LAQRS datetime extension builtin functions were added. Query language names were added for SPARQL 1.0, 1.1 Query and Update, 1.1 Query, and 1.1 Update and LAQRS. An XSD dateTime class and public API were added. Support for reading and writing RDF-encoded query result formats in RDF/XML and Turtle / N3 was added. Many other API additions, removals, and changes were made.
Release Notes: Aggregate expression execution as defined by the SPARQL 1.1 Query W3C working draft of 14 October 2010 was added, including execution grouping of results: GROUP BY; execution of aggregate expressions: AVG, COUNT, GROUP_CONCAT, MAX, MIN, SAMPLE, SUM; and execution of filtering of aggregate expressions: HAVING. New syntax parsing support was added for BINDINGS, isNUMERIC(), MINUS, sub SELECT, and SERVICE. The roqet utility was updated to execute queries over SPARQL HTTP Protocol and operate over data read from stdin, enabling it to work as a filter. Several other new APIs were added.
Release Notes: Updated to handle more of the new syntax defined by the SPARQL 1.1 Query and SPARQL 1.1 Update W3C working drafts of 1 June 2010. Execution support for new SPARQL 1.1 query built-in expressions IF, URI, STRLANG, STRDT, BNODE, IN, and NOT IN. An 'html' query result table format. Support was added for building with the Raptor V2 API. Many other fixes and changes were made.
Release Notes: The rasqal.pc file was fixed to correctly link in the raptor dependency.
Release Notes: Initial draft parsing and API (not execution) support for SPARQL 1.1 Update W3C Working Draft of 2010-01-26 was added. Public APIs were added for row, results, result formatter, and variables table so that query results can be built, read, and written without a query. Resilience checks were added to API calls for invalid NULL pointer arguments. Many other bugfixes and improvements were made.
Release Notes: An entirely new query engine that executes more of SPARQL (95%+ of the standard test suite passes) using the SPARQL algebra internally was implemented. Experimental LAQRS syntax support was added for SUM, AVG, MIN, and MAX, and execution support for COALESCE and LET. Query result formatters were added for CSV, TSV, and textual Tables. The ABI/API was changed in a backwards-incompatible fashion. Many other bugfixes and improvements were made, including more resilience to resource failure.
