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. 00013 </p> 00014 01234567890123456789012345678901234567890123456789012345678901234567890123456789 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> 00037 00038 <p> 00039 For more information, see <i>The Essential FDO</i> 00040 and the <i>FDO Developer's Guide</i>. 00041 </p> 00042 00043 <br> 00044 </div> 00045 */ 00046 00047 00048 00049
