RDF Core F2F meeting - August 1-2, 2001

Discussion around open issue: http://www.w3.org/2000/03/rdf-tracking/#rdfms-literal-is-xml-structure

Test case from M&S Specification:

<rdf:Description
  xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:dc="http://purl.org/metadata/dublin_core#"
  xmlns="http://www.w3.org/TR/REC-mathml"
  rdf:about="http://mycorp.com/papers/NobelPaper1">

  <dc:Title rdf:parseType="Literal">
    Ramifications of
       <apply>
      <power/>
      <apply>
	<plus/>
	<ci>a</ci>
	<ci>b</ci>
      </apply>
      <cn>2</cn>
    </apply>
    to World Peace &nbsp; other problems

Example representations based on n-triples:

NO GOOD:
<http://mycorp.com/papers/NobelPaper1> <http://purl.org/metadata/dublin_core#Title> (Literal, "Ramifications of <apply><power/>... ").

WHY NOT: no namespace info for <apply>

Good enough for a few (EricM, DaveB); perhaps not good enough for Graham:

<http://mycorp.com/papers/NobelPaper1> <http://purl.org/metadata/dublin_core#Title> (Literal, <n3:xml>Ramifications of <apply xmlns="http://www.w3.org/TR/REC-mathml"><power/>..."</n3:xml>).

WHY NOT (GK): xml signature is busted by shmutzing the namespaces around.

better(DanBri): make Literal into a URI
<http://mycorp.com/papers/NobelPaper1> <http://purl.org/metadata/dublin_core#Title> (http://@@.../Literal, <xml>Ramifications of <apply xmlns="http://www.w3.org/TR/REC-mathml"><power/>..."</xml>).

WHAT ABOUT ENTITIES?

<http://mycorp.com/papers/NobelPaper1> <http://purl.org/metadata/dublin_core#Title> (Literal, "Ramifications of <apply><power/>... &#160;").


DanC's noodelings....
---------
<http://mycorp.com/papers/NobelPaper1> <http://purl.org/metadata/dublin_core#Title> *xml1 .

<appendix>
<fragment id="xml1">Ramifications of <apply xmlns="http://www.w3.org/TR/REC-mathml"><power/>..."</xml></fragment>
</appendix>
---------

Conclusion: No solution yet... suggestion to look into XML Fragment as
a possible means of addressing this issue.
