    • put together basic workflow based on Brian's request for "usage details", got response from James
    • need to get an activity diagrams
    • Need clarification on post conditions
  • Apache OODT
    • Austin Introduction to Apache OODT [Download]
    • Is it a workflow system? - It's a very general system, and has a workflow engine, but not specifically designed for workflow
    • Is the CAS (Catalog and Archive) in OODT equivalent to the CAS in UIMA (no, catalog and archive service vs. common analysis structure)
    • Workflow repository and workflow engine? -

    • Does OODT capture provenance - did not find anything on it
    • Stanford free online Natural Language Processing class: https://www.coursera.org/nlp/auth/welcome - "Registration closed March 18" - but can still follow along on videos?
    • What could we use it for?
      • HAO (or possibly RAMADA might meet needs too)
      • CEDAR? Has pretty involved system already, but might be nice to move to a standard system.
    • What does this do that OpenDAP doesn't do?
      • SZ: supports more complex metadata queries than OpenDAP catalogs
      • workflow management of science processing
      • workflow of metadata extraction, better metadata cataloging
      • data archival & curation
      • file manager tracks versions of data (provenance here?)
      • resource management
      • push/pull framework (OPeNDAP only supports 'pull')
