scope:

This part of ISO 13584 specifies the requirements for an ISO-registered reference dictionary for measuring instruments with their descriptive properties and domains of values. The measuring instruments to be included in the dictionary comprise environment measuring instruments and laboratory measuring instruments. This part of ISO 13584 also specifies the procedures of an organization that develops, maintains and updates the reference dictionary for measuring instruments over a specified period of time. Such an organization is nominated by ISO and is referenced in this part of ISO 13584 as the registration authority of the reference dictionary for measuring instruments. The reference dictionary for measuring instruments contains the following: - definitions and identifications of classes of measuring instruments, with associated classification scheme; - definitions and identifications of data element types that represent properties of measuring instruments; - definitions and identifications of domains of values that prove useful for describing the above data element types. Each class, property or domain of values of this application domain constitutes an entry of the reference dictionary for measuring instruments defined by the registration authority. It is associated with a computer sensible and human readable definition, and with a computer sensible identification. Each dictionary entry has an identifier that allows it to be referenced unambiguously from any application.
