WFS

Geographic Feature Service Web known as "Web Feature Service" - WFS is a member of the Open Geospatial Consortium - OGC Consortium, the WFS standard defines Web interface operations for querying and editing vector geographic entities such as roads or rivers.

Typically, users interact with a WFS service through geospatial Web or Desktop clients, which allow access to vector map layers from outside organizations. An excellent example of using a WFS Service is to provide open and interoperable access to a large amount of spatial data over the web.
