This part of the CEN/TS 16157 series specifies the informational structures, relationships, roles, attributes and associated data types required for publishing measured and elaborated data within the Datex II framework. This is specified in three submodels, a DATEX II Measurement Site Table Publication submodel, a DATEX II Measured Data Publication submodel and a DATEX II Elaborated Data Publication submodel.
