Roadmap

Annotating Concepts within a Concept Scheme

• change preferred label (skos:prefLabel)
  • preferred labels are unique within a concept scheme
• manage (add/remove) alternative labels (skos:altLabel)
  • alternative labels are unique within a concept scheme
• manage (add/remove) scope notes (skos:scopeNote)
  • concise (typically 1-2 sentences) free text to, within a concept scheme, (1) restrict or expand the application of a concept, (2) distinguish between concepts of overlapping meaning (the concepts involved may have reciprocal scope notes), or (3) to provide advice on concept usage. Supplies some, possibly partial, information about the intended meaning of a concept, especially as an indication of how the use of a concept is limited in indexing practice.

Harmonizing (i.e., Combining) Concept Schemes

• focus on mapping a "back-end" scheme (i.e., tagged to the content -- a tagging scheme) to a "front-end" scheme (i.e., in search UI -- a retrieval scheme).
• direction of information flow is from content to user, so mappings are from tagging (non-preferred/alternate) scheme to retrieval (preferred) scheme.
• relations are skos:broadMatch (i.e., upward posting), skos:exactMatch, and skos:closeMatch ("fuzzy" match that may inform devaluation for search-result scoring).

Import/Export Concept Schemes

• be able to import SPASE scheme (has ~1000 concepts).
  • not yet in needed format (i.e., .ttl file using heliokos' SKOS subset)
