Retiring Your Metadata Shoehorn
Patrick Durusau - His paper is not in the proceedings for 2007 (it is Late Breaking)
Patrick seems to have a reputation that precedes him. There are more laughs in this room in the first 5 minutes than any other session I’ve been in so far.
Use Cases:
Content Tagging to attach metadata at the element level.
Conversion of metadata for round tripping between two complex XML models.
Extrinsic Metadata - recording of metadata seperate from document content
IP - granular application of IP claims within a document
Templates - associate with a particular template
Ontology validation - support for validation by user of metadata
He mentions many more use cases but I just can’t type as fast as he is talking…and comprehend the discussion. I knew I should have taken keyboarding in college.
Solution:
Metdata manifest - manages linkage between source and target metadata (maps XML IDs to UDIs)
- enumerates metadata files and the relationships to other files in the Opendocument package
- it associates OpenDocument elements of the document to IRIs in the metadata files
- Semantics are defined by an OWL ontology
- classes for: content.xml, styles.cml, metadata files, ODF elements
- manifest.rdf (stored at root of the package)
ODF elements and content (target)
- odf:idref and URI of its rdf:about attribute
- Accessiblity means that they attached metadata to many many elements (making it as open as possible)
- RDF/a-like metadata is allowed as well, for greater accessibility as well
Content based on metadata
- text:meta-field
- contains any paragraph content, including another text:meta-field
- content is generated by the application
Unlimited number of metadata files (source)
Painless RDF:
- RDF vocabulary of terms (metadata file)
- users enter the text (content.xml file)
- metadata manifest ‘links’ to these files
- a ’smart’; search engine adds information found in the RDF vocabulary
- Explodes the impression that hand entry is necessary to us RDF (or any other semantic technology)
Future of Robust Metadata:
- OpenDocument increases the unknowing use of XML
- OpenDocument Format metadata has the potential to greatly increas the use of RDF based metadata for documents.
- Will appear in openDocument format 1.2 (http://www.oasis-open.org)
