SCR 3-1126

SCR 3-1126: Multiple occurrences of the same keyword in an object – Valid or Not?

Priority: high

Problem Summary

A Rosetta team has presented a draft label that contains multiple occurences of the SPICE_FILE_NAME and NOTE keywords. A medium-depth search of the PDS standards documents reveals no PDS standard for how to deal with repeated keywords. The lvtool (current release 2.20) flags this as a warning of the same severity as an unmatched standard value (i.e., the sort of warning we expect to be cleaned up prior to or at final delivery). VTool does not flag the multiple occurences of these keywords at all. If multiple occurences of a single keyword within an object is valid, the PDS standards should say so and provide an indication of the significant of a repeated keyword (are the values concatenated into a series or sequence, or does one overwrite another and in what order)? If multiple occurences are not valid, the PDS standards need to say so explicitly.
