[postgis-devel] Xing Lin's SoC project (raster support)

I'm a little worried at the quantity of this document that is copied 
verbatim from the Oracle Georaster documentation.  I mean, are we just 
cribbing their whole design directly?  The Oracle model is pretty, but 
it breaks up the rasters into an internal relational model, which pretty 
much requires some sort of toolset for people to load/unload data.

Second, the documentation stops with the model, it provides no 
functions, or even hint of what functions will be done first. Providing 
objects and no functions, or no data loader, is going to be a pure Waste 
of Time. I know he's not going to have time to copy the complete set of 
Georaster functions from Oracle, so an idea of what functions he plans 
to do first is pretty important.

PostGIS 0.1 had the types, it had input/output methods, and it had index 
bindings.  If this implementation does not have a way of getting data in 
and out, it's not going to be worth the time putting it together.
