THREDDS Status Report 10/7/02

THREDDS is currently concentrating on getting dataset providers to catalog their data holdings and make them available on-line. We have recently released version 1 of a "Catalog Generator/Crawler" to help automate this. Other tools to help this process include the "Catalog Validator" servlet and an HTML viewer. Recently Raj Pandya joined our group with a joint appointment with DLESE. He will help prototype the use of THREDDS and the IDV for educational resources, which will be discoverable through the DLESE digital library.

Current areas of work include:

We are building a "THREDDS/LDM data server" to make the LDM data stream available through THREDDS.
We are developing, along with the MetApps developers, an elaboration of THREDDS catalogs for dynamic datasets, with a new XML document type called a "Query Capability" document.
We are exploring the possibility of building a "Web Coverage Server" which is a new server type from the OpenGIS consortium, that may include converting netCDF files to GeoTIFF.
We are developing, along with NCAR's SCD division, "NcML", a new XML markup language for netCDF data. New capabilities will include aggregation and augmented metadata.
We continue to follow evolving metadata standards for digital libraies and for GIS systems, and to map our datasets into those standards.
