RE: HL7 and patient records in RDF/OWL?

The unstructured-to-structured data effort will deal with how to transform
unstructured (free text), but also semi-structured data sources such as
Excel, XML, Relational db into RDF.
The 'unstructured' connotation relates to the lack of fully formalized
semantics, so, I agree with you, it's a very broad and probably vague term.
You may want to refer to the BIORDF sub-group proposal for more details
(attached).

If I am right, GRDDL is only applicable to XML document because it uses XML
transformation to convert arbituary XML file to RDF/XML.  XML is obviously
structured data, then I am confused by what you mean
"unstructured-to-structured"?
