rapper -c -q [input.rdf]
说明
rapper is a command-line utility from the Raptor RDF Parser Toolkit for parsing and serializing RDF (Resource Description Framework) data. It reads RDF content in various formats and outputs the triples in a chosen serialization. The tool supports multiple RDF syntaxes including RDF/XML, N-Triples, Turtle, RDFa, and RSS/Atom feeds. Input can be from local files, standard input (using '-'), or remote URIs when Raptor is built with network support. Common uses include format conversion between RDF serializations, validation of RDF files, counting triples for analysis, and extracting RDF data from web pages containing RDFa markup.
