Re: [office-metadata] Suggestion for next version of ODF-OWL

[John Madden <john.madden@mac.com>]

Hi again,

I also want to share with you a manifest.rdf file example (using my alternate syntax suggestion, sorry) that I think demonstrates where I think the real utility of the manifest would come in. Here it is, then some comments:

<?xml version="1.0" encoding="UTF-8"?>

                                                <!-- We obligingly use Smith Hospital's ontology to reference their patientID -->

                                                <smith:patientID xmlns:smith="http://www.smithHospital.com/enterpriseOntology#">S45678</smith:patientID>

                                    <!--  -->

</rdf:RDF>

So basically, my point here is that I think we ought to make apparent to potential users that the benefit of the manifest is fourfold (at least):

(1) simply to list the metadata files that are attached

(2) to provide versioning info about the metadata files in a machine readable way, using owl:versionInfo and related properties

(3) possibly most important to me, to expose certain odf:Elements to RDF aggregators in an easy way

(4) to expose publicly some useful assertions about the elements that were exposed in (3), particulary using owl:sameAs, owl:differentFrom and owl:AllDifferent, in conjunction with references to other ontologies.
