>Graham Klyne Post message to list describing how CC/PP uses datatypes
Specifically, I recall the action to be that I post details of how CC/PP
uses XML schema data types for literal values. The relevant document here
is [1] which is not a public document, but incorporates changes from
last-call reviews. See, for example, section 4.1.1.2 [2], 4.1.1.3 [3], and
appendix C [4].
The client vocabulary schema [4] uses the XML schema datatype as the range
of the corresponding RDF property, where the actual value is a literal
rather than an RDF class. In this context, the XML schema datatypes are
presumed to be subclasses of rdfs:Literal (?).
Example of use:
<ccpp:Attribute rdf:ID='charWidth'>
<rdfs:label xml:lang="en">Character display width</rdfs:label>
<rdfs:domain rdf:resource='&ns-ccpp;Component'/>
<rdfs:range rdf:resource='&ns-xsdt;integer'/>
<rdfs:comment xml:lang="en">
For character displays, the number of characters that can be
rendered across the display. For displays using a proportional
font, this is the display width in typographical 'em's.
</rdfs:comment>
</ccpp:Attribute>
Ooops, just spotted a couple of bugs in the appendix C schema :-(
This raises a couple of questions:
What is the data type of a resource that is a DTD?
" " XML schema?
" " RDF schema?
