7.3 NoOp operation
This engineering report defines an additional WIS operation named “NoOp” that all clients shall ignore. The NoOp operation only exists to satisfy XML validation
requirements for capabilities documents imposed by the Web Service Common standard see OGC 06-121r9, 7.4.6 which requires that OGC web services implement the
GetCapabilities operation plus one additional operation. Clearly, the web service common standard did not anticipate the usefulness of a service that only implements the
GetCapabilities request. A change request has been posted against OGC 06-121r9 to remove this requirement.
7.4 Example
In response to the following request:
http:www.somcorp.comwis?service=WISrequest=GetCapabilities
a web integration service might generate the following capabilities document:
?xml version=1.0? Capabilities version=1.0.0

specification V2.0.2 see 07-006r1 which specifies the interfaces, bindings, and a framework for defining application profiles required to
publish and access digital catalogues of metadata for geospatial data, services, and related resource information. Metadata act as generalized
properties that can be queried and returned through catalogue services for resource evaluation and invocation or retrieval of the referenced

Contents Capabilities
Since this capabilities document is composed mostly of standard OGC components it is an easy task to extend an OGC catalogue to consume this document. The catalogue can
then automatically determine which services are offered by this provider and harvest each one in turn also maintaining the associations between the web integration service and its
child services.
