ISO 15889:2003, Space data and information transfer systems - Data description language - EAST specification

ISO 15889:2003 specifies the requirements for the Enhanced Ada SubseT (EAST) language (CCSDS 0010) used to create descriptions of data, called data description records (DDRs). The use of this language ensures complete and exact understanding of space data as well as its automated transfer and interpretation on any host machine having the appropriate software tools.
