Getting Service-level Metadata About a WMS
Before obtaining a map from a WMS server, it is important to determine the names of available layers,
their contents, their SRS (spatial reference system, or coordinate system) settings, and other information
about the data. Use the GetCapabilities request to obtain this information from a server.
The GetCapabilities request returns service-level metadata in XML format. This metadata is a description
of the information content and valid request parameters of the service.
Inputs and Behaviors
The following table lists the possible request inputs:

Description
Request version. Currently versions 1.1.1 and 1.3.0 are supported.
Service type. The SERVICE attribute is always set to WMS.
Request name
The request parameters are always sent as an HTTP query string. The following is a sample GetCapabilities
request:
http://localhost:8080/rest/EnterpriseMapping/WMS?VERSION=1.3.0&SERVICE=WMS&RE-
QUEST=GetCapabilities
After a successful GetCapabilities request, the service returns a GetCapabilities response which is a
descriptive XML file. The GetCapabilities.xml file contains the information on the services metadata,
capabilities, and layers.
General Service Metadata
The first part of a GetCapabilities response contains the name of the Web service (always OGC:WMS),
the title of the Web service, and the URL of the service.
Note:
The Name is usually a single word read by a machine, while the Title is designed to be humanreadable.
