		Subject: Spatial extensions for Derby?
		
		
		I'm wondering if there is any interest in
having/developing spatial extensions for Derby?  I can see value in
having Derby available as an embedded database for working with large
spatial datasets.
		 
		I expect that adding spatial to Derby would involve:
		- defining spatial types
		- implementing a spatial index (probably an R-tree)
		- adding spatial query and manipulation functions
		 
		As the developer of the JTS Topology Suite API, I would
be happy to offer this package as a component of a spatial
implementation in Derby.  Feel free to contact me if this is of
interest.
