netCDF-Java and the THREDDS Data Server
Version 4.6.11
The NetCDF-Java/Common Data Model (CDM) library and THREDDS Data Server (TDS) version 4.6.11 were released on December 4th, 2017. These are stable releases, and as such, the development team recommends these upgrades 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.
