NcML-G/sub ML/: encoding NetCDF datasets using GML

We describe the NcML-G/sub ML/: an extension of the NetCDF markup language (NcML). Such extension allows to encode NetCDF dataset resorting to GML 3.0 elements. It was conceived to facilitate the interoperability between the atmospheric science and the GIS communities; NcML-G/sub ML/ leverages the NcML effectiveness for encoding multidimensional arrays, encoding geo-metadata in GML. The abstract and the general content model which lead to the NcML-G/sub ML/are described.
