TDB
From Semantic Portal Wiki
TDB is a triple store that uses a native indexing and storage. SDB is a related triple store that uses a relational db for storage. Both are affiliated with Jena.
tdbloader and tdbquery are command line tools that will load and query a tdb triple store, respectively.
Although tdbloader accepts a --graph argument, it tries to parse .trig files as rdf/xml. This imposes some undesirable work to make the .trig look like a .ttl and spoon feed the graph name through the command line argument. -Tim Lebo
