A state of affairs with respect to OpenGIS standards, i.e. standards of the Open
Geospatial Consortium (OGC), in open source software. How good do the different
projects communicate through OpenGIS standards? Several open source projects (among
others Mapserver, Geoserver, MapGuide Open Source, Mapbuilder, Chameleon, uDIG) will
be  evaluated with respect to their implementation of OpenGIS specifications (for
instance WMS, SLD-WMS, WFS, WMC). Do they talk well out of the box, or does it need
specific tips and tricks to get things running? Do the clients (Chameleon, uDIG,
Mapbuilder) communicate well with proprietary systems like ESRI's ArcIMS or Ionic Red
Spider?
