All,

When dealing with rdf:XMLLiteral's which includes HTML entities such as ’ does preference go to:

  • Including the Entities in a <!DOCTYPE section
  • Double encoding &amp;rsquo;
  • Converting the chars to plain Unicode characters of their numerical form. &#000;

Cheers,

I assume you ask how to write such entities in an RDF/XML document?

To maximise portability, and that includes people round-tripping the data through different syntaxes and/or stores I'd recommend that you use the numeric forms in RDF/XML (and appropriate escaping in other syntaxes).

So true. Don't expect characters outside of US-ASCII to live through many transitions from one to another system.

XML Literals are supposed to be in exclusive canonical form. If I read correctly that means you ought to do the following:

  • Use the literal character except...
  • in attribute values use &amp; &lt; &quot; &#x9; &#xA; and &#xD; for the relevant character.
  • in text content use &amp; &lt; &gt; &#xD;

So for &rsquo; you should enter '’', the character itself.

Serialisations other than rdf/xml may impose further restrictions. For example in N-Triples you must encode everything beyond US-ASCII, so <span>’</span> would be written as <span>\u2019</span>.

They are supposed to be in canonical form after parsing. This does in no way imply that they should be written in canonical form in RDF/XML. Canonicalization is the RDF/XML parser's job.
