Hey all,

I am in the process of evaluating FDO for my gis application.  I am stuck
with C#, so thankfully FDO has Managed bindings.  So far I have been playing
with the WMS provider, and mostly with success.  But i cant seem to find
answer for some questions, hopefully you guys can help me out here.  Most of
my questions revolve around the WMS provider as its the only one I ve played
with so far.

1) Can i get access to all the layers meta properties, so far using the jpl
and metacarta WMS servers i can only seem to ever get 2 properties, i) the
id, and ii) the raster property.  Is this just cause the WMS servers I am
hitting don't provide any more properties?  Also the abstract that most WMS
servers provide?

2) The WMS provider seems to support reprojecting, (through the override
raster definition, but i havent tested this yet) I imagine this is cause WMS
in general support reprojecting, do the other providers support this?

3) I dont understand the abstract feature i get in the WMS schema's, this is
probably just my stupidity.

4) Is there a significant performance hit in general using FDO.

5) Has anyone written more tutorial info for FDO, i find my self looking to
the unit tests for info.

6) Do any of the spatial db providers, provide support for rasters in the
db, or just geometry?
