H Capabilities Description (Current)
Prev |  | Next

# H Capabilities Description

A Capabilities Description is a WADL Document. See [WADL].

The Capabilities Description resource follows directly and unambiguously from the RESTful resources defined in Chapter 10, Chapter 11 and Chapter 12.

The WADL document shall contain one top-level "application" element.

The "application" element shall contain one "resources" element whose "base" attribute value is the base URL for the service. This may be a combination of protocol (either http or https), host, port, and application.

Additionally, the WADL content shall include a "resource" element for the Target Resource specified in the request describing all methods and child resources for the specified resource and each of its children.

The full resource tree and the methods defined for each resource are described in Table H-1.

### Note

The Retrieve Capabilities Transaction is excluded from Table H-1 because that transaction is used to retrieve this document and WADL is not self-describing.
