Status Update

A summary of working THREDDS catalog servers and analysis and display tools is available at:

<http://www.unidata.ucar.edu/projects/THREDDS/currentwork.html>

A few highlights are:

• a catalog of THREDDS catalog servers which can be accessed from within the IDV tools at
  <http:///motherlode.ucar.edu:8080/thredds/topcatalog.xml>
• educational modules with embedded data access and interaction via the VGEE analysis and display tools. Go to the DLESE site and search for resources referring to "thredds" -- for example <http://dpc.ucar.edu/vgee/t1a3s.htm>
• a pointer Benno Blumenthal's LDEO IRI web site that allows the user to employ the LDEO analysis and display tools on datasets on the UCAR server. <http://iridl.ldeo.columbia.edu/%28http://motherlode.ucar.edu/dods/uniCat.xml%29readthredds/>

Expanding the available servers and clients:

Keep our current data providers involved and add THREDDS capability for:

• Web Services data providers (Follow up on contact with Wenli Yang at GMU and UAH people)
• OpenGIS (This is closely related to web services; Follow up on contacts with Stefano as well as with Carl Reed and George Schellof OGC). This evolution will provide interfaces in the future.
• Legacy GIS (Follow up on many contacts at ESRI, including Jack Dangermond). ESRI is providing tools for data providers to make their data available via the web. They are also interested in our 5D visualization capabilities. They also have considerable experience with and a deployed system for metadata and discovery. See for example, the Geography Network.
• GRID (Follow up with Luca and the other ESG people)

Keep our current data access and display sites involved and add:

• Education oriented GIS client (Pin things down with Danny Edelson at Northwestern)

Tools for automated metadata generation form basic THREDDS catalogs:

• Gazetteers (UCSB, Linda Hill and Jim Frew)
• Disciplinary ontologies and the semantic web(Rob Raskin at JPL and Stefano's multilingual European group)
• Data mining (UAH, Steve Tanner)
• ESML generator (UAH, Rahul Ramachandran)

New Interdisciplinary coordination

• GEON (Follow up with Chuck Meertens)
• CUAHSI (Follow up with Anton Kruger)

Etc.

We should also consider the relationship to our DLESE Data Services proposal partners: Tamara Ledley at TERC and Mike Taber of U of Northern Colorado.

Proposals are due on April 21, 2003. Letters of intent (optional, but
encouraged) are due March 12, 2003.
