Besides client applications which provide a classic user interface, the OX-Framework can also be used to build server applications which encapsulate, chain or orchestrate other OGC services. Thereby, the access to other OGC services is facilitated by the OX-Framework. The RESTful SOS is such a server application which is build on top of the OX-Framework. It encapsulates SOS instances and works as a proxy to an SOS for providing a RESTful interface to the data.

The design principle of this application is shown in the figure below. The RESTful SOS acts as a proxy to the actual SOS and transforms retrieved URL calls to SOS queries of the GetObservation operation. The proxy is also able to transform the observations encoded in the Observations ans Measurements (O&M) format to other data encodings, such as RDF, KML, or a diagram representation.
