[SAO] multiple omit_set groups

[Takahiko Kawasaki]

It seems impossible to define multiple omit_set groups under the current specification of SAO (Selective Abort/Omit). I’m not sure whether such use cases should be covered, though.

If we think that there can be uses for such a feature, we should add it. We could do something like omit_set[0] and omit_set[1], etc. to label the groups.

However, I think that the most common, if not the only, use case will be for the RP to define a dataset that must be sent together or not at all. The RP can thereby prevent paying for claims that are useless to it. I’m not sure if an RP will ever need to define two separate sets of data for which this applies.

Do you have a use case in mind where this could be useful?

No, no use case in my head. I pointed this out just from a theoretical point of view. If you recognized the theoretical possibility but concluded it was unnecessary when you drafted the spec, omit_set[*] is not needed and the current spec is good enough. I just wanted to confirm this before starting to implement the SAO spec. 😅

[Daniel Fett]

Ok, thanks! Then let’s keep it in its current state until a use case pops up.

Taka and Daniel agreed this could be closed
