netCDF-Java and the THREDDS Data Server
Version 4.6.4
The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.6.4
releases were finished on February 12th, 2016. This is a stable release, and as such, the development team recommends this upgrade to anyone using the CDM or TDS.
The THREDDS Data Server (TDS) is 100% Java, open source, and runs as a Tomcat web server application. TDS data serving capabilities are built on top of Unidata's netCDF-Java / CDM library. The CDM data model combines the NetCDF-3, DAP2, and HDF5 data models, into what is called the Common Data Model (CDM). It has a pluggable "I/O Service Provider" architecture that allows it to read various file formats into the CDM, including NetCDF, HDF5, GRIB, NEXRAD levels 2 and 3, and others, as well as datasets served through the OPeNDAP protocol. The TDS then builds data services on top of the CDM.
