Presentation Transcript

  1. Specifications document • A number of revisions & refinements done => upcoming revision of design document • Summary: • support smart data discovery • find data that matches some semantic constraints • support matching of pipeline steps and data sets • support chaining of pipeline steps • dependent on what type of AP/“director” is used • know about and reason with data/type/unit conversions

  2. Semantic Mediation System notes from the breakout session

  3. Software Components/Products • ontology languages/handler • languages for semantic types, data types, other constraints • system for type checking and reasoning with semantic types

  4. Relations to other Components • EcoGrid uses SMS for smart data discovery • 2do: What is an analytical step?  AMS • Eco-model, piece of a model, (sub-)workflow, data-massaging step, visualization • 2do: Use cases where two analytical steps can/can’t be chained together  BEAM • 2do: Use Ptolemy to do some Ecology models and find out which Ptolemy directors are relevant for SEEK (discrete event models, process networks, ...) • 2do: (within SMS) • type systems for parametric polymorphism vs reasoning with measurement scales, aggregation, sampling protocols, scaling theory, ...

  5. Calendaring, Meetings • yes

  6. Milestones • Milestone0: finish hiring asap • Milestone1 (?May/June 2003): • initial choice of ontology language for SW1 (RDF, RDF(S), DAML+OIL, OWL, ...) and • initial tools (Fact, Protege, ... Jena (HP sem web activity)... • prelim. overview on possible type checking, query planning and reasoning procedures for SMS

  7. Deliverables for June 1 • SMS design document • initial choice of ontology languages, and frameworks for reasoning with them • initial design of API: SMS AMS/EcoGrid
