Hello Daniel, thank you for the response. The solution that uses an instance of a parser doesn't work I think for the reason that I have written, there is no instance available outside the OSGi service platform (Fuseki). The code that I use is
org.apache.clerezza.rdf.core.serializedform.Parser parser = org.apache.clerezza.rdf.core.serializedform.Parser.getInstance(); InputStream is = subjectUrl.openStream(); Graph subjectGraph = parser.parse(is, SupportedFormat.RDF_XML); returns an UnsupportedFormatException For the solution with the Jena parser I need a MGraph implemetation since the parse method of the Jena parser requires the graph as an attribute. org.apache.clerezza.rdf.jena.parser.JenaParserProvider parser = new org.apache.clerezza.rdf.jena.parser.JenaParserProvider(); InputStream is = subjectUrl.openStream(); MGraph subjectGraph = <???> parser.parse(<???>, is, SupportedFormat.RDF_XML, null); Can you tell me what kind of implementation of the MGraph can I use to pass to the parse method of the JenaParserProvider ?
