空间数据和信息传输系统.参数值语言规范

[中文适用范围]： 本国际标准规定了空间数据和信息传输系统参数值语言规范的要求。 所附 CCSDS 出版物的第 1.1 和 1.2 条进一步详细说明了应用范围和领域。 [外文原描述]： 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.
