About one year ago Sergey Melnik created a table to "summarize some 
current approaches to storing RDF in a relational database":

 http://www-db.stanford.edu/~melnik/rdf/db.html
 
Since then, there have been several announcements on this mail list 
regarding RDF stores.  To consolidate information about the various 
systems used to store RDF, I would like to compile a list of RDF 
storage systems and then for each system, gather some useful data 
about the system.

Attached is a list of RDF/triple storage systems.  If a system is 
missing, send its name and a URI where there is more info about the 
system.

Authors/owners (of the items on the list or items missing from the 
list) - please consider describing your system with some or all of 
the following metrics and feel free to add other metrics or useful 
information:

o Scalability (any limits?)

o Performance 

o Provenance support

o Inference support (forward/backward chaining) & expressiveness of 
 the deductive query language

o Licensing issues (e.g. GPL)

o Concurrency and transaction support (real transactions?,
  full roll back?  journalling?)

o API issues (e.g. range of language bindings available)

o Query (language used, etc.)

o Platform issues - (e.g. Unix, Linux, Windows etc.)

o Support for distribution (e.g. federation, replication etc.)

Also attached is a list of related papers/systems.  Additions to 
this list are welcome.

If there is interest, I will put this info on the W3C's web
site and try to maintain it.
