You would still have to do all the other things.

What RDFDB gives:
  * import/unimport RDF xml-files
  * insert/delete triples
  * a basic query language

What RDFDB misses:
  * It does not bind statements to models
  * It does not make the 'fact' shortcut for reified statements
  * No alias mechanism
  * No container optimization
  * No support for uri prefixes
  * No support for blobs
  * No URI asignment for statement
  * No RDFS methods
  * No checking of duplicate statements

The experience with the RDF Schema editor
http://jonas.liljegren.org/perl/proj/rdf/schema_editor/ made us want to
optimize for the most common case. That is: the realy heavy use of types
and subClassOf and the constant use of label in the development
enviroment.

It does make it easy to import RDF data and to make queries.  But it will
not be a good place to store the bulk of the data from Wraf.


So: I would like to have an interface to RDFDB. It may be a little easier
to do some queries.  But it doesn't cut back on the work we have to
do.  RDFDB is too limited to be used as the main storage interface.  It
should only be used with simple static data.
