Purpose/Rationale

The CEOS International Directory Network (http://idn.ceos.org) is an international effort developed to assist users in locating data sets, data services, and visualizations. We provide free, online access to metadata on scientific data in the Earth sciences: geoscience, hydrospheric, biospheric, satellite remote sensing, and atmospheric sciences.

The metadata describes data held by university departments, government agencies, multinational, and other organizations. It is maintained using the standard Directory Interchange Format (DIF), Service Entry Resource Format (SERF), and Climate Diagnostic (CD) Format.

Activities:

The IDN Interest Group is responsible for coordinating activities among the participating agencies to maintain, improve, and expand the functions and use of the IDN. Efforts include:

• maintaining the content for the CEOS IDN site (http://idn.ceos.org)
• maintaining the IDN server and clients to improve metadata search capabilites
• maintaining and adding new metadata records from CEOS agencies
• maintaining usage statistics and report these to CEOS agencies
• maintaining the DIF, SERF, and CD metadata standards using the INTEROP forum
• creating new CEOS portals as requested by partners
  

IDN Services:

• IDN CSW access:Procedures for accessing the IDN CSW Testing Server (http://idn.ceos.org/docs/CSWaccess.pdf)
• Connect to the IDN Metadata Web System (MWS) and Keyword Management System (KMS) RESTful Web Services (http://gcmd.nasa.gov/Connect)
  

• DIF documents and tools
