Current release: sqltriples 0.3.3
    (currently requiring pyPgSQL or
    pysqlite2 (or the sqlite3 module in
    Python 2.5) and CMDsyntax
    0.91)
The sqltriples distribution consists of a Python module which provides an
    RDF triple store whose data is stored in an underlying SQL-accessible
    database system, with an API resembling that of the original rdflib TripleStore
    class, but with extended API methods for the convenient retrieval of
    nodes, triples and tuples optionally involving the combination of
    results to form complicated queries. Currently, supported database
    systems include only PostgreSQL
    (via pyPgSQL) and
    sqlite (via pysqlite2).
The sqltriples distribution is licensed under the LGPL version 3 (or later).
