WMTS
OpenGIS Web Map Tiling Service (WMTS) Interface Standard.
Aus [1]: The candidate WMTS Interface Standard is much like the OGC’s popular Web Map Server (WMS) Interface Standard, but it enables better server performance in applications that involve many simultaneous requests. To improve performance, instead of creating a new image for each request, it returns small pre-generated images (e.g., PNG or JPEG) or reuses identical previous requests that follow a discrete set of tile matrices. This proposed standard provides support for multiple architectural patterns – KVP, REST and SOAP.
Reference implementations: Geowebcache, Carbonarc project and some others.
"The WMTS spec is much more complex, and 'fully featured', as is common in specs designed by committee. Practically speaking, if OSGeo's Tile Map Service does what you need, you won't need WMTS.
