NcML is an XML representation of netCDF metadata, (approximately) the header information one gets from a netCDF file with the "ncdump -h" command. NcML is similar to the netCDF CDL (network Common data form Description Language), except, of course, it uses XML syntax.
NcML development is happening on two fronts:
- NcML-2.2 as implemented by the NetCDF-Java library.
- NcML-Gml is an extension of ncML core schema, based on GML grammar.
