ncML-Gml is:

• an Abstract and Content Model reconciliation schema for ES and GIS info realms
• a Mediation Markup Language between ncML (netCDF Markup Language) and GML
• an extension of ncML core schema, based on GML grammar

At the moment, to support some legacy software packages, ncML-Gml is not a standard GML profile. This will be fixed in a future release.

Here you can find the XML Schema (version 0.7.3).

A slide presentation and a paper on ncML-Gml v.0.5 are available at:

• GML Days presentation
• ncML-Gml 0.5

 

ncML-Gml Java API

A Java API to convert netCDF-CF datasets to ncML-Gml is made available here.

The API supports dataset trasformations according to the roadmap that follows (taken from GALEON IE). Current version is 0.9.

 

Test Dataset	Coverage domain	Coverage co-domain	CRS	Dataset size	version
simple	2D + T	scalar (single)	Geo	small	ver 0.2
sst	2D + T	scalar (single)	Geo	medium	ver 0.4
sst-2v	2D + T	scalar (array)	Geo	medium	ver 0.6
trid	3D	scalar (single)	Geo	small	ver 0.7
striped_can	2D + T + P	parametric	Geo	large	ver 0.8
ruc	3D + T + P	parametric	Geo + Proj	large	ver 1.
