Re: [office-metadata] Further examples needed

[Elias Torres <eliast@us.ibm.com>]

An Example RDF/XML file using our Ontology:

<rdf:RDF xmlns="http://www.w3.org/2000/01/rdf-schema#";
    xmlns:meta="http://opendocument.xml.org/2007/03/meta-manifest/ns/#";
    xmlns:dc="http://purl.org/dc/elements/1.1/";
    xmlns:owl="http://www.w3.org/2002/07/owl#";
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
    xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#";>

<meta:Manifest rdf:about="urn:uuid:[document-uuid]">
  <meta:entry>
    <meta:Entry rdf:about="urn:uuid:[name-graph-uuid]">
      <rdf:type
rdf:resource="http://example.org/plugin/photo-meta#MetaFile"/>
      <meta:full-path>meta/photos-meta.xml</meta:full-path>
    </meta:Entry>
  </meta:entry>
</meta:Manifest>

</rdf:RDF>

The RDF/XML generates the following triples:

@prefix meta: http://opendocument.xml.org/2007/03/meta-manifest/ns/# .

<urn:uuid:[document-uuid]> a meta:Manifest ;
  meta:entry <urn:uuid:[name-graph-uuid]> .

<urn:uuid:[name-graph-uuid]> a meta:Entry ;
  a photo:MetaFile ;
  meta:full-path "meta/photos-meta.xml" .

Worth noting:

The rdf:type http://example.org/plugin/photo-meta# is an example of a
classification scheme added the plugin itself. Plugins can add extra
metadata to the manifest as they wish in order to provide useful
information for themselves or others in future access.

I shortened ManifestEntry to just Entry now.

The rdf:about for the Manifest *could* be used as the stable global doc ID
from our conversation today.

The rdf:about for the Entry *could* be used as the stable global id for the
Named Graph.
