NetCDF-Java library and TDS version 4.6.13 ReleasedFebruary 19, 2019
The goal of Unidata's Thematic Real-time Environmental Distributed Data Services (THREDDS) is
to provide students, educators and researchers with coherent access to a large collection
of real-time and archived datasets from a variety of environmental data sources at a number
of distributed server sites.
The THREDDS Data Server (TDS) is a web server that provides metadata and data access for scientific datasets, using a variety of remote data access protocols.

Unidata embarks on new projects to help make its data and tools available to a broader, more diverse audience. The following are a list of THREDDS Data Server-related projects between the Unidata Program Center and external collaborators.
Unidata's Common Data Model (CDM) is an abstract data model for scientific datasets. It merges the netCDF, OPeNDAP, and HDF5 data models to create a common API for many types of scientific data. The NetCDF Java library is an implementation of the CDM which can read many file formats besides netCDF.
