Wraf implements a RDF API. The purpose is to enable the construction of applications that fully uses the RDF data model in order to realize the Semantic Web.
Wraf uses interfaces to other sources in order to integrate all data in one enviroment, regardless of storage format. You can read and update information from configuration files, databases, XML files, LDAP, etc.
The system will use intelligent caching and optimizations in order to gain in speed without sacrifice any flexibility. A persistant backend service deamon will take requests from clients in mod_perl. Other non-browser interfaces could also use the service.
Wraf will be idealy suited for complex, interconnected systems there the addition of new data often breakes the previous format and the exceptions is the rule. It can be used for personalized content generation, topic communities, intranets and more.
