Hi Massoomeh,

I recommend Notepad++ or rdfEditor https://bitbucket.org/dotnetrdf/dotnetrdf/wiki/UserGuide/Tools/rdfEditor  for editing RDF documents. But RDF Translator http://rdf-translator.appspot.com/  might be really useful for you, too, to convert XML to RDF or to check for well-formedness of RDF-formatted content

Dear all,
I'm trying to create/write some records based on CIDOC-CRM model in RDFxml format.
Could you please introduce a free RDFxml tool editor which it's easy for beginers?
