Depends on what you have in mind. For databases similar to your example, I
believe ORCID has an API. GNIS, ULAN, CONA, and TGN might be interesting to
you, but there are tons more, particularly if you add subject authorities
(e.g. AAT, MeSH). The Getty stuff is all available as LoD.

Implementation would be specific to your system and those you wish to
interact with. The MARC record is used to represent/transmit data, but it
doesn't actually exist in the sense that systems use it internally as is.

Having said that, I think the logical place to put control numbers from
different schema is in 024 because that field allows you to differentiate
the source so it doesn't matter if control numbers overlap
