nao:description "NRL was designed for knowledge representation in Nepomuk Social Semantic Desktop applications. While being built on top of the Resource Description Framework (RDF) and the associated RDF Schema (RDFS), it addresses several limitations of current Semantic Web languages, especially with respect to modularization and costumization. These questions seem to be important not only in Semantic Desktop scenarios but also on the general Semantic Web. NRL tackles these questions by including support for two main additional concepts: Named Graphs and Graph Views. Named graphs help coping with the heterogeneity of knowledge models and ontologies, esp. multiple knowledge modules with potentially different interpretations. The view concept allows for the tailoring of ontologies towards different needs in various exploiting applications. This view concept provides also the basic mechanism to impose different semantics on thesame syntactical structure." .
