Platform ID


Definition
Unique identifier of the Platform Ancillary Description.
 
Syntax
<SEntry_ID> Unique identifier of the Platform Ancillary Description </SEntry_ID>
 
Specifications
  • Required field.
  • May be used only once.
  • 1 to 31 alphanumeric characters from the printable UTF-8 character set, except ">"
  • Should be written in all capital letters.
  • Must be selected from the Platform Keywords (see Appendix A) if updating the document.
 
Recommendations
  • The platform identifiers (short names) are semicontrolled; i.e. new platform identifiers may only be added if the platform does not already appear in the Platform Valids List.
  • The identifier is usually a mnemonic or abbreviated version of the long name. When submitting a new identifier, always check the Platform Valids List to ensure mutual exclusivity among platform short names. No two platforms may have the same short name.
 
Example
  • <SEntry_ID> EO-1</SEntry_ID>
