Ivan, All,
Indeed we did not resolve the XMLLiteral issue aka the default
data type issue), yet.
The rather good news: There is an issue in Tracker, now [1].
The bad one: We still have to decide what we want/need ;)
Current status:
+ We are talking about section '5.1.1.1 XML Literals' in [2]
+ Mark has put together a comprehensive list of options we have [3]
Regarding this issue I have made the following observation
that I'd like to discuss with you:
Referring to [4], the XML Content within an RDF Graph is
quite unambiguously defined. The definition says:
'RDF provides for XML content as a possible literal value.
This typically originates from the use of rdf:parseType="Literal"
in the RDF/XML Syntax. Such content is indicated in an RDF graph
using a typed literal whose data type is a special built-in data type
rdf:XMLLiteral, defined as follows ...'
amongst other things, the definition contains
'a lexical space that is the set of all strings which are
well-balanced, self-contained XML content [5]'
Taking the following fragment as an example input
<div about="">
<h1 property="dc:title">
E = mc<sup>2</sup>: The Most Urgent Problem of Our Time
</h1>
</div>
I would assert that this does not conform to the definition
of a well-balanced, self-contained XML content as of [5] due
to the fact that the content of the <div> does not start with
an element.
Any thoughts?
Cheers,
Michael
