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:
“The best political economy is the care and culture of men; for, in these crises, all are ruined except such as are proper individuals, capable of thought, and of new choice and the application of their talent to new labor.”
—Ralph Waldo Emerson (1803–1882)
