00006 There is NO public API documentation for the FDO Provider for WFS.
00007 Functionality is available only through the main FDO API.
00008 
00009 <p>The Feature Data Objects (FDO) API provides access to data in a 
00010 data store. A provider is a specific implementation of the FDO API 
00011 that provides access to data in a particular data store. The FDO 
00012 Provider for WFS provides FDO with access to a WFS-based data store.

00015 <p>An OGC Web Feature Service (WFS) provides access to geographic features that 
00016 are stored in an opaque data store in a client/server environment. A client 
00017 uses WFS to retrieve geospatial data that is encoded in Geography Markup 
00018 Language (GML) from a single or multiple WFS. The communication between client 
00019 and server is encoded in XML. If the WFS response includes feature geometries, 
00020 it is encoded in Geography Markup Language (GML), which is specified in the 
00021 OpenGIS Geographic Markup Language Implementation Specification. WFS is a 
00022 read-only provider.
00023 </p>
00024 
00025 <p>A WFS schema can support the following:
00026 </p>
00027 <ul>
00028   <li>Inheritance
00029   <li>Multiple schemas
00030   <li>Object properties
00031   <li>Association properties
00032   <li>These geometry types: point, line string, polygon, multi-point, 
00033   multi-line string, multi-polygon, multi-geometry, curve string, curve polygon, 
00034   multi-curve string, multi-curve polygon, linear ring, line string segment, 
00035   circular arc segment, and ring.
00036 </ul>
