The Climate and Forecast (CF) Conventions community has released the CF 1.8 conformance document. There are a number of major improvements in that document which now also support geometries (similar to Shape and KML) as point, line, polygon and multiples of these. The most recent version of the document is available at http://cfconventions.org/latest.html.
