rapper − Raptor RDF parser utility |

The rapper utility allows parsing of RDF content by the Raptor RDF parser toolkit emitting the results as RDF triples in a choice of syntaxes. The source-URI can be a file name or if Raptor is built with a WWW retrieval library, a general URI. The optional base-URI is used as the document URI if present. |
