ISO International Standard

ISO 14961:2002 specifies the requirements for a parameter value language (PVL) specification for space data and information transfer systems. It establishes a standard keyword value type language for naming and expressing data values and provides an overview and formal syntax specification of the PVL. Two versions of PVL are defined, the basic version (CCSD0006) and an extended character set version (CCSD0008).

The specifications in this ISO 14961:2002 are applicable to all space-related science and engineering data exchanges where a keyword value language is desired.
