Updates on the CEOS IDN Jianping Mao On Behalf of Lola Olsen, IDN, Task Team Lead CEOS/WGISS-25 February 25-29, 2008
Table of Contents • Reemergence of the Interoperability Forum/Communications • Update on Directory Population and Usage • New in MD9.8 – early spring • Finding Earth Observation Platforms and Instruments: Feedback from WGISS Action Items • Progress in Development of Controlled Vocabularies • Nodes Reports/Collaborations
IDN Interop Forum • Use the Interop Forum as a mechanism to inform and discuss innovations and modifications for IDN future. • Message #1 - MD9.7 • Message #2 - DIF/SERF XML schema changes in future releases.
DIF Population Growth SERF Population Growth Holds ~ 21,000 metadata records (References > 20 petabytes)
Searches by Controlled Keyword 4/2000 – 12/2007
New in MD9.8 – early spring release • New User Comment Form to discover: “Who are users?” • MySQL database to replace Oracle. • Website to highlight portals and keywords. • Update DIF/SERF/AD Writer’s Guide. • Embedded link checker to update broken URLs. • International characters using UTF-8 (to please IDN users.) • “Private” fieldfor data/service providersto restrict access to data sets/services not ready for public access. • DIF display for horizontal spatial coverage extended to poles and also extended to the vertical domain.
Finding Earth Observation Platforms & InstrumentsWGISS Action Item 24-24 by IDN • Tyler Stevens to coordinate the group of Bernd Ritschel, Jolyon Martin, Jean-Pierre Antikidis, Karen Moe, Wyn Cudlip and Terence van Zyl to create a list of requirements for evaluation by the IDN team and presentation at WGISS-25. These requirements shall describe a cross-mission search capability, which would enable users to searchmissions and sensors by application.
Requirements:Platform/Instrument Search Interface • Capitalize on existing platform and instrument ancillary information: • CEOS Earth Observation Handbook • NASA Science Reference Handbook • GCMD Descriptions • Utilize new technology to create an intuitive interface. • Provide capability to sort platform and instrument information by columns in sequential order. • Enhance capability to refine search within interface. • Link directly from instrument to platform descriptions and vice-versa, and to associated metadata and then to data.

Earth Science Keyword Status In 2007, the keyword hierarchy was expanded (internally) to two additional levels. A new TOPIC, Biological Classification, was added and inspired the extension of the entire science keyword taxonomy to five levels. The TOPIC, Hydrosphere, was clarified by adding the modifier, ”Terrestrial". The number of digits in the version number was thus extended to five to include Variable Levels 2 and 3. Thus, the Version Number now stands at 6.0.0.0.0, because of the changes at the “Topic” level (Level 1) and should be cited as: ”GCMD Keywords, Version 6.0.0.0.0”. The "Detailed Variables" continue to serve as a critical component of the keyword taxonomy, by providing a level to specify uncontrolled, descriptive keywords of the author’s choosing.
Earth Science Keyword Status Because of the broad usage of the GCMD keywords in other systems around the world, we remain respectful of those who wish to incorporate changes. Therefore, we are dedicated to providing mappings of the changes. These mappings will be provided to the user community through our new MySQL database, which handles “triggers” of these changes more capably than the Oracle database. More work remains on extending the thousands of keywords to controlled Variable Levels 2 and 3. The release of the new database is planned to precede the completion of these keywords to accommodate the extended keyword sets and the synchronization of modifications. The public will be informed when this work is completed. Work is in progress!
