The GerPS-Datafield is an extension for the GerPs-Onto. Besides the Procceses there are also forms, that contains the data that will be proccesed in Public Service. For this purpose there is the XDatenfeld-Standard as an XöV-Standard. Its basicly an XML-protocoll for trasmitting data about these forms, but its not an semantic standard. So the GerPS-Datafield is the Semantic Version of this XDatenfeld-Standard. We integrated it in the GerPS-Onto to make this more interoperable and extend the possibilities to work with this semantic standards.
