I think there is an issue with integrating sample data and mission data,especially in an era of increasing sample return.  In some cases,there an obvious overlap (e.g. reflectance spectra) and lab (sample) dataare posted on PDS alongside reflectance spectra obtained by observatoriesand missions.  But what about the direct chemical and physicalanalysis of extraterrestrial samples?  At the moment data arediffused through the literature or are in private and commercialdatabases, with a lot of duplication of effort.  Is there a case forNASA creating a sample node on the PDS where the analyses of allextraterrestrial samples can be posted?   

I agree that at the moment the PDS is a hodge podge where some entriesare essentially individual publications and others require voo doo magicto access.

Please send me or circulate yourthoughts about the issues that need to be addressed on this topic thatshould be built into the outline. This will be the basis for discussionduring my presentation on this at the SBAG meeting in Pasadena on Aug 4.

Examples of issues on my mind are:

* Missions tend to strive for meeting minimum (and minimal) dataproduction and archive requirements. This makes it more difficult fornon-mission scientists to extract science from the mission. Part of theproblem is that data product generation and archiving is a late phaseactivity, subjecting its (usually underestimated) budget to raidingearlier in the mission.
* Data products should be available in formats broadly usable by theplanetary community. There is a tendency among instrument teams to createnon-standard products suited to in-house analysis programs (diminishingexternal competition in the analysis of the data).
* Planetary research programs have supported the acquisition of largevolumes of data sitting in the offices of researchers. Is PMDAPsufficient to encourage the archiving of this data?
* How should archiving of data from future research funded by planetaryresearch programs be encouraged or required? Could part of the fundingsupplied by NASA to ground-based facilities such as IRTF be used toensure that data generated to PDS compliant standards with requiredancillary files automatically generated?
* How easy is it for researchers to find data archived in the PDS (ordetermine it is not there)? Are adequate tools and interfaces provided byPDS for the small bodies community?
