RDFStore [1] is a BSD-licensed lightweight native RDF storage written in C/Perl which uses a ad-hoc hashed storage with various compressed multi-dimensional sparse matrix inverted indexes. It supports simple SPO, RDQL [2] and fetch_object [3] query methods - free-text Unicode indexing and stemming on literals is fully supported. As well as indexing of rdf:datatype and xml:lang literal properties. Graph naming (contexts/provenance) is fully supported at the API and query level - and graphs can be serialized to RDF/XML and N-Triples containing full naming information [4]. It also includes pure perl RDF/XML and N-Triples parsers which passes all positive RDFCore tests [5]. For a more detailed description of the DB back-end see http://www.asemantics.com/presos/SWAD-E/SWADe-rdfstore.html as presented [6] at the SWAD-e storage and retrieval workshop [7] in Amsterdam last November Various demos and demonstrators has been build [8][9][10][11][12] with the toolkit. Lastest code is aval on CVS at SourceForge cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/rdfstore login cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/rdfstore co rdfstore or latest snapshot bundle at http://rdfstore.sourceforge.net/downloads/snap.tgz - we successfully compiled the package on BSD, OSX, Linux, Solaris and Gygwin. hope this helps Albe [1] http://www.rdfstore.com/ [2] http://www.w3.org/Submission/2004/SUBM-RDQL-20040109/ [3] http://www.joseki.org/RDF_data_objects.html [4] http://lists.w3.org/Archives/Public/www-rdf-interest/2004Feb/0209.html [5] http://www.rdfstore.org/testcases/ [6] http://www.asemantics.net/presos/SWAD-E/swad-e-rdfstore/ [7] http://www.w3.org/2001/sw/Europe/reports/dev_workshop_report_4/ [8] http://demo.asemantics.com/rdfstore [9] http://demo.asemantics.com/biz/nb2/ [10] http://earth.esa.int/isc/ [11] http://demo2.asemantics.com/biz/rdfa/ [12] http://www.asemantics.com/n/solutions/wadi.html
