Russian Federation CDMS 12 Catalogue database schema Russian Federation CDMS 13 Implementation OpenGIS® Web Feature Service (WFS) Implementation Specification Functions: – Create a new feature instance – Delete a feature instance – Update a feature instance – Lock a feature instance – Get or query features based on spatial and non-spatial constraints Russian Federation CDMS 14 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 Russian Federation CDMS 15 • A web feature service may be able to service transaction requests.
