Hi Jody,

Last year I extended Christian's imagemosaic-jdbc module to support Oracle 
Georaster.  This however, was quite a dirty implementations and had a 
dependency on about 11 external Oracle java libraries (which, is not workable 
in the opensource world!).

The imagemosiac-jdbc module was then officially extended by the community, 
however, it is limited to only working with the Oracle Georaster format if a 
mosaic has been created in the DB.

What I have created in collaboration with another developer (Baskar Dhanapal), 
and would like to release to the community, is a plugin, which is dependant 
only on one external Oracle Library (the Oracle JDBC Driver ojdbc14.jar), and 
works with the most common GeoRaster data model, where there are many raster 
tiles for a given dataset and does not rely on the DBA to create a mosaic 
within Oracle.  An example of this would be the Ordnance Survey 1:10,000 scale 
raster products, where there are 10,585 tiles.  To create a mosaic for this is 
timely, high maintenance (as mosaic would need to be re-created even if a few 
tiles were updated) and costly in storage.  The proposed module would mosaic on 
the fly, and take out those issues mentioned above.

I hope yourself and the community see the benefit to having this module, and 
accept this as a formal request to submit.  We will definitely be using this in 
the WMS service we provide to Ordnance Survey(GB) in the current Geoserver 
upgrade to 2.1.0 for INSPIRE compliance in the coming months.

Kind Regards,

Steve Way
