What is a Web Feature Server?
A basic Web Feature Server can handle 3 types of request:

• GetCapabilities. Describes using an XML-encoding the capabilities of the service, e.g. the features that are available and the supported transactional operations.
• DescribeFeatureType. Provides a description of the structure of a given feature type (i.e. the schema).
• GetFeature. Provides access to features based on a filter that constrains the request using spatial and non-spatial parameters.
