Yes, no problem.

And OpenLayers can read both.  Any particular reason for going the

We have a Javascript client which works with JSON. We are planning to avoid
including Geoserver to keep things lite.

By geospatial metadata, you mean polygons? It's something we could include
in the future, but it is something that is relatively static, so for now,
distributing that in separate files should not be a problem. Still, it may
be an interesting option to have in the future.

Then KML would be much handier.


KML is definitely on the table with a number of solutions we are looking at
in Geneva as well. So yes, but less urgent.

Straightforward, but big, if you have any kind of accuracy.
