SCR 3-1087: PDS Standards on Sequences (formerly “PDS Standards on Sequences and Sets”)
Priority: high
Problem Summary
The PDS standards regarding sequences and sets are described in sections 12.5.5 through 12.5.6.1 of the PDS Standards Reference. This SCR proposes to resolve several inconsistencies and/or ambiguities in these sections.Correct the BNF notation for 2 dimensional sequences shown in section 12.5.5 to sequence_2D ::= (sequence_1D [, sequence_1D]*)Determine whether the following is a valid sequence:(99, (0,1), 88, (1,2), 77, (2,3))After AVERAGE_ECCENTRICITY example in 12.5.5, provide examples of heterogeneous and 2 dimensional sequences.Revisit current restrictions on sets described in 12.5.6.1. For example, why aren’t real values permitted?Discuss whether or not to permit 2 dimensional sets.

It’s unclear whether vtool (actually the underlaying ODL parser) implemented the standard as it is or the proposed change. Impact may be understated since the parser may need modification and testing.
