Web feature service
WFS-T is a bidirectional extension to this service, making it possible to modify objects on the client side and record them with the server. For example, the following Open Source servers are supporting this protocol.
- deegree (EU INSPIRE portal will be based on this)
- GeoServer (very popular)
- Mapserver (read only, no WFS-T)
- TinyOWS (new challenger)
There's currently no WFS service containing worldwide OSM data available. However, OSM-GB project provides a layered WFS service for the Great Britain window based on its processed dataset (as well as WMS). Demo service at http://184.108.40.206/cgi-bin/tinyows may also be available (data only from Finland).
