yes, i think its worth considering in the future. this would make structure members first class citizens. the attributes would apply to the structure member as a whole, not individual array elements, just as for an array dataset.Hi John,the motivation comes from creating a unifying model with the opendap data model.We've got a question: is there a way to attach an attribute to a member of a compound type dataset. That is, if I have a dataset of something that is a compound type, can I attach at attribute not to the whole dataset, but just to one member of the compound type?Hmm, we've had a couple of requests for similar features, but you can't do this currently. What's the motivation for this?I think I will let John answer this part...opendap structures contain "first class" variables that can have attributes.Hmm, interesting...however, if thats not feasible, i can do a workaround where opendap structures become groups instead.Well, it definitely isn't currently supported. Should I open an issue for this in our tracker so we consider in the future? I'm just a bit concerned about supporting the full generality of it, like attributes on parts of array datatypes or nested compound datatypes, etc. Quincey
as i said, the motivation comes from opendap structures. ironically, i suspect that it was at least in part motivated there by mapping hdf (4/5?) into opendap, where they decided to map "groups" into "structures". so we can just undo that and map opendap structures to groups when needed.
