One item may involve data from many ontologies

The tradeoff

LocalWider
Local reuse onlyWider reuse
Local termsGlobal or shared terms
FastTakes effort

Semantic Web optimizes the tradeoff

Data owners should

  1. Take inventory
  2. Decide priorities, most likely benefits
  3. Look for existing ontologies
  4. Don't change the way data is managed
  5. Set up standard (RDF, SPARQL) portals onto existing data
  6. Where necessary, adapt or write new ontology bits

Forms of openness

Linking out

Incentive: kudos

Limitations of access control

Track provenance of data

Most semantic web processing systems are aware of provenance
