PDS4 and NSSDC Some Questions (Not to be answered now!) Will PDS4 Data Sets have unique identifiers? (i.e. Will every change made to a data set result in a new version number?) Will Checksums be required or optional? (Separate files delivered with data sets?) What will a delivery “package” look like? Will existing PDS3 data sets be delivered as PDS4 and will there be a timetable for this? How long will the period of concurrent PDS3 and PDS4 deliveries last?
CD-ROMs / DVDs NSSDC currently holds multiple copies of CD- ROM and DVD sets (originally for distribution). One copy of each volume is stored in our archive. Many of these sets have been replaced by newer versions now stored as AIPs. So what do we do with the CD-ROMs and DVDs that have been superseded? What is PDS doing with theirs?
NSSDC Hard-Copy Archive The Press Release Photograph collection has been inventoried and is being sent to NARA. Disposition of the planetary film collection is awaiting NARA negotiations with Johnson and JPL. Moving it offsite will be expensive. The disposition of the microfilm/microfiche collection is still under discussion.
