Redland and Raptor – what are they?
Redland is the RDF library written in C and including several high-level language APIs providing RDF manipulation and storage. Redland requires Raptor and cannot be used without it since it uses URI and WWW retrieval parts even if no parsing is being performed. The Redland sources currently include Raptor, although this may change. Raptor is the RDF parser library written in C dealing with reading RDF/XML and N-Triples syntaxes (more eventually) into RDF triples. It is an entirely standalone and separate library from Redland, developed and released on a different schedule.
