将RDF转换为OWL

Question

I want to generate RDF code that follows the OWL format. I am able to generate an RDF file, but I need to convert it into OWL. Below is the RDF that I can generate.

<?xml version="1.0" encoding="UTF-8"?>
<rdf:RDF
   xmlns:ns1="http://example.com/nodetypes/2012/04/24/vehicle/"
   xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
>
  <rdf:Description rdf:about="http://example.com/nodetypes/2012/04/24/vehicle/2">
    <ns1:nodetype_ptr_id>2</ns1:nodetype_ptr_id>
    <ns1:slug>vehicle</ns1:slug>
    <ns1:last_update>2012-04-24 23:49:36.633689</ns1:last_update>
    <ns1:end_publication>2042-03-15 00:00:00</ns1:end_publication>
    <ns1:tree_id>2</ns1:tree_id>
    <ns1:featured>False</ns1:featured>
    <ns1:parent_id>None</ns1:parent_id>

    <ns1:level>0</ns1:level>
    <ns1:creation_date>2012-04-24 23:49:15</ns1:creation_date>
    <ns1:status>2</ns1:status>
    <ns1:template>gstudio/nodetype_detail.html</ns1:template>
    <ns1:content_org>None</ns1:content_org>
    <ns1:excerpt></ns1:excerpt>
    <ns1:plural>vehicles</ns1:plural>
    <ns1:comment_enabled>True</ns1:comment_enabled>
    <ns1:password></ns1:password>
    <ns1:title>vehicle</ns1:title>
    <ns1:login_required>False</ns1:login_required>
    <ns1:pingback_enabled>True</ns1:pingback_enabled>
    <ns1:rurl></ns1:rurl>
  </rdf:Description>
</rdf:RDF>

Answer 1

As cygri says, the job is done. However, there are now two additional normative syntaxes: OWL/XML and the Functional syntax which is used to specify what's an OWL ontology and to specify its direct semantics. In addition to these, there are non-normative syntaxes for OWL: The Manchester syntax and all the RDF serialisation syntaxes ( Turtle , N-Triples , Notation3 , JSON-LD , RDF/JSON , HDT , etc). The RDF Working Group is working at making Turtle a standard , as well as a JSON serialisation .

In order to switch format, you can use the converter at University of Manchester , which can output RDF/XML, Turtle, OWL/XML, Manchester syntax, Functional syntax and also LaTeX (for nice rendering in articles).

Edit: Since February 2014, Turtle , N-Triples , N-Quads , and Trig are normative syntaxes for RDF.

Answer 2

You're already done. What you have there is an RDF/XML file. The normative syntax for OWL is RDF/XML. So it is an OWL file too.
