Redland RDF library (librdf) from [http://librdf.org/] == License == [git:redland/LICENSE.txt] Triple-licensed: LGPL v2+/GPL v2+/Apache v2 Note that Sun distributes this software only under LGPL v2 == Description == This module contains the third-party Redland RDF / librdf library, which is needed to support data in RDF (Resource Description Framework) format. It consists of 3 parts: - raptor: parsers and serializers for numerous RDF file formats - rasqal: query engine which supports SPARQL queries - redland: librdf integrates raptor and rasqal, and provides numerous storage engines for storing RDF graphs (in memory, SQL, ...) Libraries: libraptor, librasqal, librdf == Patches == There are several patches, most of which contain only hacks to get it to build with OOo build system. There used to be also 3 patches here that fix bugs in redland and ought to be of general interest: - redland-1.0.8.patch.free_null: redland destructor functions don't check if argument is NULL - redland-1.0.8.patch.storage_hashes_context_serialize_get_statement: hashes storage: the function to create statements during serialization does not fill in the context propery (i.e. context is NULL) - redland-1.0.8.patch.storage_hashes_list_duplicates: hashes, list storage: if contexts are enabled, then it is possible to add duplicate statements Attempts to upstream these patches failed for reasons upstream kept to themselves. Now these patches are replaced with workarounds in unoxml. Note to future maintainers: work around redland bugs in client code.
