Topics

Moderator: Matt Jones

Agenda

  • Updates: Overview and Progress
  • Ontology-based browsing and searching
    • Actors
    • Data
  • Coherent file-manager with caching for actors and remote services (see IdentifiersInKepler)

    • using LSIDs for identifying actors and services
    • relationship to an 'Actor Repository' and EcoGrid
  • Pipeline integration tasks
    • Actor-actor integration
    • Data-actor integration
      • How do we annotate datasets, and what can we do with it if we do
      • Utilizing Jenny Wang's schema matching tool
  • Distributed execution of kepler models
    • Choosing one (or more) distributing computing platforms
    • Should the Director be kept in the computation?
    • Dynamic loading of jar files with actors
  • Data access in ecogrid
    • query, get, put, etc.
    • should these be instantiated as actors?
    • archiving kepler products in the ecogrid
      • how do we generate appropriate metadata for archived products?
    • semantic annotation/registration for EcoGrid data objects
  • Actors -- do we have a complete set?
    • GIS actors -- more needed?
    • Statistical actors
      • Anova, regression, various other stats nicely wrapped up (wrap R?)
  • Integrating R scripts in a semantically-meaningful way
  • Kepler UI
    • what's right, what's wrong, what can we realistically fix
    • guidelines on how to consistently extend and organize the Kepler UI
  • From-scratch design of a semantics-driven UI
    • what would we build in a world free of contraints
  • Goals and work plan for the next year

Notes from the kepler breakout meeting on 11/3/04

  • Ontology based browsing and searching
    • add functionality to add new actors to the ontology
    • add functionality to change ontology views
    • add functionality to allow user to put actors into different folders in an ontology
    • add functionality to suggest actors that can be used with other actors (SMS)
    • add functionality to add ontologies
    • change categorization to a connection based cat.
      • choose an actor then the org would change to be only actors that would work with the chosen one.
  • 3 interfaces
    • browse
    • search
    • contextual reduction of actor base

  • Semantic Mediation
    • New EML module to describe processing

  • data management
    • search, organize, store data (morphepler)
    • query subsystem
    • filesystem management ala morpho
      • some see a need to control the file management for controlling ids and file locations
      • could specify a directory(ies) that would hold the data/metadata. the user would then drop objects into that area for the system to process.
      • system could be searched for kzip (or whatever) files and periodically updated. would need a system wide index of kzip files.
    • workflow transfer system
      • zip up workflow so it can be easily transfered
      • don't require the use of the ecogrid
      • archive format
        • workflow, data, actors with metadata for each (verifiable-checksum, etc).

  • method descriptions for workflows
    • extend EML method
      • OWL in AdditionalMetadata?
    • other possible metadata standards
      • OWL?
      • Others?
    • ACTION ITEM: need a workflow metadata language for semantically describing the workflow


Meeting notes

Kepler and SMS/KR integration tasks

  • Annotate a specific set of data sources and targets (probably from Matt's fake example)
  • Annotate the "component library" so that we know what functions they perform and how they relate to the "conversion" tasks that are needed for a given integration task
