-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Rasqal RDF Query Library 0.9.33 http://librdf.org/rasqal/ Rasqal is a free software / Open Source C library that handles Resource Description Framework (RDF) query language syntaxes, query construction and execution of queries returning results as bindings, boolean, RDF graphs/triples or syntaxes. The supported query languages are: SPARQL 1.0[3] SPARQL Query 1.1[4], SPARQL Update 1.1[5] (no executing) and Experimental SPARQL extensions (LAQRS). Rasqal can write binding query results in the following formats: SPARQL XML, SPARQL JSON, CSV, TSV, HTML, ASCII tables, RDF/XML and Turtle / N3, mKR and read them in: SPARQL XML, SPARQL CSV, TSV, RDF/XML and Turtle / N3. Rasqal was designed to work closely with the Redland librdf[1] RDF library and the Raptor[2] RDF Syntax Library but is entirely separate from both. This is a beta quality library - the code is mature, the API is mostly stable but changing slowly. Rasqal supports all of SPARQL 1.0 query and most of SPARQL 1.1 query. It is a portable library and has been tested on multiple POSIX systems and architectures. Rasqal has no known memory leaks. The main changes in this version since the last release 2014-02-23 are: * Added support for reading and writing boolean result formats. * Fixed several query engine operator evaluations (AVG, STRBEFORE, STRAFTER, CONCAT) * Updated query results class constructor and methods, deprecating older. * Portability fixes for ICC, clang and GCC 5. * New internal test runner utility * Variable bindings query results can be formatted in mKR CSV format. * Multiple other fixes and improvements including fixing reported issues: 0000546, 0000568, 0000583 and 0000588.

Rasqal 0.9.33 requires Raptor 2.0.7[2] or newer to provide RDF syntax, web, XML and URI support. Optional requirements are a POSIX regular expression library such as PCRE or one built into the C library to handle regex matching / replacing; a multi-precision decimal library such as GNU MP or MPFR for handling XSD decimals; a UUID library for generating unique IDs. Binary deb packages for Debian unstable will be made available later via the standard Debian archive.
