API Reference OSGeo FDO Provider for WFS

Introduction

Note:
There is NO public API documentation for the FDO Provider for WFS. Functionality is available only through the main FDO API.

The Feature Data Objects (FDO) API provides access to data in a data store. A provider is a specific implementation of the FDO API that provides access to data in a particular data store. The FDO Provider for WFS provides FDO with access to a WFS-based data store. 01234567890123456789012345678901234567890123456789012345678901234567890123456789

An OGC Web Feature Service (WFS) provides access to geographic features that are stored in an opaque data store in a client/server environment. A client uses WFS to retrieve geospatial data that is encoded in Geography Markup Language (GML) from a single or multiple WFS. The communication between client and server is encoded in XML. If the WFS response includes feature geometries, it is encoded in Geography Markup Language (GML), which is specified in the OpenGIS Geographic Markup Language Implementation Specification. WFS is a read-only provider.

A WFS schema can support the following:
