As indicated, this XML Schema uses the owsServiceIdentification.xsd, owsServiceProvider.xsd, and owsOperationsMetadata.xsd schemas specified in [OGC
05-008].
8.3.5 Exceptions
When a web image classification server encounters an error while performing a GetCapabilities operation, it shall return an exception report message as specified in
Clause 8 of [OGC 05-008]. The allowed exception codes shall include those listed in Table 5 of [OGC 05-008], if the updateSequence parameter is implemented by the server.
8.4 Examples 8.4.1 GetCapabilities
request
To request a capabilities document, a client could issue the following GetCapabilities operation request with minimum contents encoded using KVP:
http:laits.gmu.eduWICS_ISODATA?service=WICSrequest=getCapabilities
The corrsponding minimum request encoded in XML is:
?xml version=1.0 encoding=UTF-8? GetCapabilities xmlns=http:www.opengis.netwics
xmlns:xsi=http:www.w3.org2001XMLSchema-instance xsi:schemaLocation=http:www.opengis.netwics WICS.xsd
service=WICS
8.4.2 GetCapabilities response
In response to such a request, the web image classification server might generate a document that looks like:
?xml version=1.0 encoding=UTF-8? Capabilities xmlns=http:www.opengis.netwics
