Hi Doug,
trying to implement an SSA service I still have some questions
concerning the contents of the votable which my service is supposed to
return:
In the SSA Data Model Summary in appendix D of SSAP V 1.02 I feel some
ucds are missing: e.g. Dataset.DataModel (might be "meta.version"?),
Dataset.SpectralSI ("meta.unit;em.wl"?), Dataset.FluxSI"
("meta.unit;phot.flux"?). Any special reason for that?
In the section "Protocol" of the summary table (on first page) there are two namespaces defined for SSA and spectrum data model. Does this mean the utypes in the queryResponse and metadataResponse must have exactly these prefixes? Or can I use any prefix, just make sure it defines the SSAP namespace rsp. the Spectrum Data Model namespace?
Where do I need the Spectrum Data Model namespace? Up to now I only used SSA - utypes. I still do not see the difference. To me it looks like the SSAP subsumes the spectrum data model. (I admit, I haven't studied it thouroughly.)
Thanks!
Best regards
Ulrike Stampa, GAVO
