Add 'set' property to data for objects in a set

[tacman]

I'm looking at the JSON records for the set of objects consisting of

• https://www.clevelandart.org/art/1916.972
• https://www.clevelandart.org/art/1916.972.a
• https://www.clevelandart.org/art/1916.972.b

They are 3 separate records but belong to the same "set", however, I don't see any json data indicating that. Obviously, I can hard-code something that says "anything with a dot-letter in the accession_number field is part of a set", but that doesn't feel particularly elegant.

Is it possible for you to add a "set" property?

Thank you for your consideration.
