Pretty RDF/XML

This library allows writing of XML RDF. It is similar to the oxrdfio writer, however, unlike oxrdf, it is aimed at producing a readable syntax by taking the various shortcuts that the RDF specification provides for. So, for instance, this longer piece of RDF:

<rdf:Description rdf:about="http://www.w3.org/TR/rdf-syntax-grammar">
  <ex:editor>
    <rdf:Description>
      <ex:homePage>
        <rdf:Description rdf:about="http://purl.org/net/dajobe/">
        </rdf:Description>
      </ex:homePage>
    </rdf:Description>
  </ex:editor>
</rdf:Description>

<rdf:Description rdf:about="http://www.w3.org/TR/rdf-syntax-grammar">
  <ex:editor>
    <rdf:Description>
      <ex:fullName>Dave Beckett</ex:fullName>
    </rdf:Description>
  </ex:editor>
</rdf:Description>

<rdf:Description rdf:about="http://www.w3.org/TR/rdf-syntax-grammar">
  <dc:title>RDF 1.2 XML Syntax</dc:title>
</rdf:Description>

will be shrunk using multiple property elements to this:

<rdf:Description rdf:about="http://www.w3.org/TR/rdf-syntax-grammar">
  <ex:editor>
    <rdf:Description>
      <ex:homePage>
        <rdf:Description rdf:about="http://purl.org/net/dajobe/">
        </rdf:Description>
      </ex:homePage>
      <ex:fullName>Dave Beckett</ex:fullName>
    </rdf:Description>
  </ex:editor>
  <dc:title>RDF 1.2 XML Syntax</dc:title>
</rdf:Description>

The library uses its own RDF data model which is similar to oxrdf but is, however, fully owned but generic. This library can therefore operate directly over, for example, Rc<str> without requiring conversion to String instances.

There are also translators for the oxrdfio data model and WriterQuadSerializer meaning that this library can be used in a pluggable way to output any oxrdfio format.
