The purpose of the ANSI N42.42 standard is to facilitate manufacturer-independent transfer of information from radiation measurement instruments for use in Homeland Security. This standard specifies the XML data format that shall be used for both required and optional data to be made available by radiation instruments. The structure of the data is described by an XML Schema (.xsd) file. The schema file allows XML parsers to validate the format of instrument data files: it defines the standard names for data elements and attributes, whether or not they are optional or required for each class of instrument, and the hierarchical relationships between them. A graphical version of the schema (1.7 MB) is also available.
