Data Transport

What data formats should we use?

Image formats other than FITS (SIA allows GRAPHIC types)? Table formats other than VOTable (e.g. csv exports from apps are easy and readable by TOPCAT)?
In general, I think a separate message for each format is probably safest - although Topcat is happy with csv, maybe Aladin isn't - although it's happy with votable. This gets more blurred with things like spectra - where there's many different formats, and representations for formats. So maybe it's a per-message-definition issue, not part of the messaging spec itself. -- NoelWinstanley

Do we need to send a data subset (i.e. rows from a table or image ROI only)?

Do we need to share access to data (rather than passing references and each app making a copy)?
