XÖV
XÖV (from the German, "XML in public administration"; sometimes written XOEV) is a German framework for defining, governing and publishing data-exchange standards used by public authorities. It provides methods, rules and tooling for modelling and maintaining sector-specific specifications (the “XÖV standards”) to enable interoperable, machine-readable data exchange across federal, state (Länder) and local administrations, and between government and external parties.
