Lists,

I'm trying to find out whats the difference between;

OSGeo TMS (tile map service)
http://wiki.osgeo.org/wiki/Tile_Map_Service_Specification

and

OGC WMTS (Tiled WMS)
http://www.opengeospatial.org/standards/wms  (on discussion)


One can see that the reference implementation of TMS on;

Servers
TileCache
http://www.tilecache.org/
Clients
Worldkit: http://worldkit.org/tilemap/
Openlayers: http://openlayers.org/
Cadcorp SIS: Screenshot


for the OGC WMTS, I read that Geowebcache, carbonarc project and some
others have done (looking for the list also, will do some research)

Now, whats the difference and WHY two different standards on tile from
the geo community? Just curious.. is there any big difference between
the TMS and WMTS?

Thanks

Bruce
