integration with editors, etc.

DC-dot demo
• http://www.ukoln.ac.uk/metadata/dcdot/• (canned demo)

Your problem…
• build ‘discovery’ service• primarily textual documents• multiple formats (HTML, MS-Office, PDF,
…)• full-text index vs. metadata-based
approach• consider discovery-strategies that aren’t
well supported by full-text approach– subject browse
– author search
– resource-type search
5
Your problem…
• focus on functional requirements• what do you want people to be able to
do

Issues
• metadata schema– simple DC, qualified DC, e-GMS, …
• cataloguing guidelines– format of author names, etc.
• workflow issues– who creates metadata– using what tools– who checks/validates/enhances metadata
• terminology (controlled vocabularies)– dc:subject, dc:type
7
Issues
• encoding issues– embedding in HTML?– XML linked from HTML?– RDF/XML linked from HTML?– embedded into other formats (MS-Office,
PDF, etc.)
• available tools– editor support for metadata– search engine support for metadata
