WCS Core, Extensions, and Application Profiles
The WCS suite is organized as a Core, which every WCS implementation must support, and a set of extensions defining additional functionality. Implementers can choose which extension to support, but there are some basic rules to be obeyed - for example, every WCS implementation must support at least one communication protocol and at least one data encoding format. To ease overview, extensions have been grouped along five categories: data model, encodings, service model, protocols, and usability. Application Profiles, finally, establish domain-oriented "bundles" of the WCS Suite. Some of these specifications are briefly presented below.
Adopted WCS standards are available from the OGC WCS page.

Famous quotes containing the word application:
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
