Dan, John and Peter

  1. Overall priorities for the project
    1. Cataloging system - directory level
      1. THREDDS underlying technology - assumes that the THREDDS technology does what we need
      2. How are the THREDDS catalogs shared

        1. LDAP master-server
        2. Peer-to-peer where every OPeNDAP server has a built in peer-to-peer mechanism built into them (Dan's choice)
    2. Fileouts

      1. Codec for fileouts
    3. Servers - CGI based to servlet based dispatch
      1. Activities at a server site

        1. Administration
        2. Adding data
          1. Adding recognized file formats - drag and drop
          2. Configuration required - ESML already provides an interface for this.

        3. Cataloging
      2. What is needed to facilitate these tasks
        1. GUI

        2. webform for installation
      3. Metrics
      4. James started a TWiki page on some of this on 18 February 2004. This link added by PeterCornillon 16 April 2004.

    4. Semantic data model

      1. Objectives of semantic data model
        1. John thinks it addresses 2 fundamental solutions
          1. Creates a taxonomy - John's version of an ontology - taxonomy editing
          2. Dimensional system, e.g., georeferencing system, allows calculations to be done based on location

      2. Mechanisms
        1. XML
        2. RDF

        3. Custom
  2. How does the ODC fit into enhance or be enhanced by the above?
    1. What's the objective of the ODC?

      1. Making it the tool of choice for the user to find and acquire data.
        1. User?
          1. Researcher - high end user
          2. Data provider to facilitate testing, providing access to... their data

        2. What is required to make it the tool of choice?
          1. Fileouts
          2. Plotting - We're real close on this one!
          3. Finding - Search panel

          4. Selection - Retrieve panel
          5. Add-ins or equivalent
            1. Excel - done

            2. Access - done
            3. IDL - done
            4. Matlab - done
            5. netCDF Clients

    2. Needed to achieve objectives
      1. Facilitating use

        1. Consistent catalogs would help the ODC a lot.
      2. Enhanced functionality
        1. Fileouts
        2. Geolocation selection capability

      3. Extending existing functionality
        1. Add-ins
          1. netCDF Clients

            1. John will send an e-mail to Steve exploring with him the idea of a Ferret command that acquires a URL list from the ODC.
        2. Additional search interfaces
          1. WIST - WOCE Integrated Search Tool

          2. ECHO
          3. MEL
          4. Peer-to-peer cataloging system

  3. Other things that John might get involved in.
    1. Spiffing up the NVODS data set list - John will do.
    2. Core stuff

      1. Java
      2. Cataloging
      3. Server stuff
      4. AIS
    3. Other non-REASoN related stuff

      1. OBIS-OPeNDAP connector
