Operations
• GetCapabilities
• A web feature service must be able to describe its capabilities. Specifically, it must
indicate which feature types it can service and what operations are supported on each
feature type.
• DescribeFeatureType
• A web feature service must be able, upon request, to describe the structure of any
feature type it can service.
• GetFeature
• A web feature service must be able to service a request to retrieve feature instances.
In addition, the client should be able to specify which feature properties to fetch and
should be able to constrain the query spatially and non-spatially.
• GetGmlObject
• A web feature service may be able to service a request to retrieve element instances
by traversing XLinks that refer to their XML IDs. In addition, the client should be able to
specify whether nested XLinks embedded in returned element data should also be
retrieved.
• Transaction
