Hi Emanuale,
We've been building out various text formats for access to point and model
data in RAMADDA. The TDS and RAMADDA provide time series extraction
services for grids. Currently there isn't any good standard for writing
gridded data as a text file.
In RAMADDA we've been working on a JSON encoding. We use Unidata's Java CDM
for the heavy lifting and the transform the CSV timeseries into JSON. We
are looking for some feedback on this JSON format. It is really (really)
new and I will be writing up documentation today as a matter of fact.
