Descriptions for interop

and automation

Grid and Pervasive share issues in large scale distributed systems. e.g. service description, discovery, composition; autonomic computing. These can be aided with semantics.

Pervasive applications

need the Grid,

e.g. Sensor Networks

Grid applications need

Pervasive Computing

e.g. Smart Laboratory

CombeChem Semantic Datagrid
  • Existing datastores linked by RDF triplestores
  • Around 80 million triples in 3store
  • A social experiment! e.g. Chemists built ontology for units
  • Chemists appreciate powerful queries and flexibility
  • Metadata infrastructure is in place

reflections
Reflections
  • This is about the intersection of the digital and physical worlds
    • Proof of concept
    • Best practice is emerging through case studies ‘in the wild’
    • Lots still to be done – the real world is messy!
  • Information perspective
    • Anticipated vs. unanticipated re-use
  • Key principle is ‘Semantic Annotation’
    • Capture contextual metadata at source
    • Maintain provenance
  • Can use Semantic Web technologies
