Definition
Unique identifier of the Project Supplemental.
 
Syntax
PEntry_ID:
 
Specifications
  • Required field.
  • May be used only once.
  • 1 to 31 alphanumeric characters from the printable ASCII character set, except ">"
  • Should be written in all capital letters.
  • Must be selected from the Project valids (see Keywords) if updating the document.
 
Recommendations
  • The project identifiers (short names) are semicontrolled; i.e. new project identifiers may only be added if the project does not already appear in the Project Valids List.
  • The identifier is usually a mnemonic or abbreviated version of the long name. When submitting a new identifier, always check the Project Valids List to ensure mutual exclusivity among project short names. No two projects may have the same short name.
 
Example
  • PEntry_ID: NASA/ESIP
