Raptor RDF Parser Library

Rasqal is a free software / Open Source C library that handles Resource Description Framework (RDF) query syntaxes, query construction and query Execution returning result bindings. The supported query languages are SPARQL and RDQL. Rasqal was designed to work closely with the Redland RDF library but is entirely separate. It is intended to be a portable library working across many POSIX systems (Unix, GNU/Linux, BSDs, OSX, Cygwin) win32 and others. This is a beta quality library - the code is mature but the API is still changing and the SPARQL support is under active development. See the todo list for the current state information. A summary of the changes can be found in the NEWS file, detailed API changes in the release notes and file-by-file changes in the CVS ChangeLog. Rasqal provides: * An RDF query construction and access API. * A query execution engine including constraint expression evaluation. * A query result binding API. * Query language support for SPARQL. * Query language support for RDQL. * Triple store querying APIs to support running over external RDF grap
