【国外标准】 Information technology - Addressing - Part 4: International postal address components and template language

Defines key terms for postal addressing, postal address components and constraints on their use. Specifically, the standard defines postal address components organized into three hierarchical levels: elements, such as organization name or postcode, which have well-defined conceptual meaning and are not themselves made up of subordinate components, though they may be sub-divided for technical purposes; constructs, such as organization identification, which group elements into units form a logical portion of a postal address; segments, such as addressee specification, which group-related postal address constructs and/or postal address elements into units with a specific defined function. This standard also specifies a mechanism for creation of sub-elements, which correspond to either sub-divisions of element content, such as door type or door indicator or to multiple occurrences and locations of elements in an address, such as levels of administrative regions.
