[Live-demo] Re-categorising OSGeo-Live projects

[Peter Baumann]

hm, while I still find that Web Services in this field mostly are data services, 
I'm looking into the classification again finding that, eg, 52north is listed 
multiply. Therefore, let me suggest to resolve the dichotomy with
- Web services:
     rasdaman/petascope -- WMS, WCS, WCPS, WCS-T, and WPS server
- Data store:
     rasdaman - multidimensional raster database
