Re: [Geoserver-users] Creating new datastore.

[Justin D. <jde...@op...>]

Hi Bernd,

Hmmm, yeah implementing the mapping as a XSLT is probably simpler then 
writing your own datastore. Especially since your target schema is 
static and the xml input format sounds simple.

So then all you need is a simple servlet / service in geoserver which 
ties it all together.
