The draft of the EN standard 17071 is now available in German translation too.
This standard defines a concept for a uniform structure of data (including data elements, syntax and semantics) for type labels with RFID transponder (including HF, UHF, NFC), 2D-dsymbol (including Data Matrix and QR-Code) and plain text.
In addition this standard specifies a minimum set of common data, that are required on data carriers, if for the same item several data carrier technologies are used.
Further on this standard provides a guidance for the creation of specific application standards, to improve interoperability and backward compatibility.
The German version can be downloaded via the Normen-Entwurfsportal des DIN.
As project editor for this standard I am also directly available for questions.
