Bill's suggestions

["Drummond Reed" <drummond.reed@cordance.net>]

Bill,

Thanks for the very helpful analysis of the RDF predicate mapping of the 5
RDFX verbs. Paul Trevithick sent me a note with a similar analysis and I
believe identical conclusions (we need time to study them closely).

I also think that "as" is a brilliant suggestion as the English equivalent
of the $data predicate. I kept wondering about that one and you nailed it on
the head.

See my next message about the recurring question of naming of the five
predicates.

I won't be able to attend the telecon, but wanted to post some thoughts
on the RDFX doc:

It would make seeing the RDF fidelity easier if the five root RDFX
predicates table contains a column that maps to the equivalent RDF
predicate, specifically:

Predicate		English	Relationship	RDF style Predicate
$ref			"is"		equivalence
owl:equivalentClass
$ref$object		"is a"	inheritance		rdf:type (if
subj is an object, owl:class otherwise)
$link			"has"		aggregation
exns:hasXXX, where XXX is the property name specified within the link
XRI
$link$object	"has a"	composition		exns:xxx, where xxx is
the property type specified within the link XRI
$data			""		datatype
rdf:parseType

I'd also suggest an English phrase for data: "as", ex: "as String"
But..is $data meant to represent actual data, or the datatype? Put
another way, what is the relationship of 
	@example+foo$data 
to 
	@example+foo// 


Exns is the prefix for a domain-specific namespace.

On the 3 col graph, I like it, though I'd like to see it bigger to
labelling is clearer.

On tightening the XRI syntax within the schema there's a fairly easy way
that makes it clear, and doesn't impose a further burden on
implementers, but does allow them to do automated checking if they want:
use schematron extensions within the schema.

Bill

AGENDA


1) XRI SYNTAX 2.1 COMPACT SYNTAX PROPOSAL

We'll review the most recently updated proposal at:

        http://wiki.oasis-open.org/xri/XriCd02/CompactSyntax


2) MXRI SYNTAX PROPOSAL

We'll review the updated proposal for MXRI syntax. It has been revised
to more closely match the HXRI syntax rules. See the final section of:

        http://wiki.oasis-open.org/xri/XriCd02/Xri2dot1Formats


3)  RDFX V2 PROPOSAL REVIEW

Drummond, Marty and Laurie will report on the discussion with Mark Wahl
on Wednesday, February 7th.
We'll also continue last week's discussion about the RDFX proposal by
reviewing the updated RDFX V2 proposal at:

 
http://www.oasis-open.org/committees/download.php/22169/xdi-rdfx-model-v
2.pdf

Supporting schemas, instance documents and the graph model powerpoint
document are available at:

        http://www.oasis-open.org/committees/documents.php?wg_abbrev=xdi


4) IDENTITY SELECTOR SUPPORT FOR XRI

We'll raise the issue about the need to define schema types for XRIs and
more specifically for inames/inumbers. We'll define action items for
addressing this issue.


5) ADDITIONAL AGENDA ITEMS TO BE DETERMINED
