Announcing the release of NcML Coordinate System 1.0 "beta" and
examples, at:
http://www.unidata.ucar.edu/packages/netcdf/ncml/
"There are currently three parts to NcML with separate schema documents:
NcML Core Schema represents the existing netCDF data model, and is at
release 1.0.
"NcML Coordinate System extends NcML Core Schema and extends the netCDF
data model to add explicit support for general and georeferencing
coordinate systems. It is at release 1.0 beta.
"NcML Dataset extends NcML Core Schema to use NcML to define a netCDF
file, similar to the ncgen command line tool, as well as to redefine,
aggregate, and subset existing netCDF files. This is at release 0.6 alpha.
"All of these have reference implementations in the NetCDF Java library,
version 2.1.
