[RDF] rdfdb

[Stefan Andersson]

This text is actually something of a statement. Maybe we ought to
compile a mini-FAQ on a page somewhere 'why WRAF instead of NN'?

> 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
