[Archivesspace_Users_Group] ArchivesSpace API questions

[Kevin W. Schlottmann]

Hi Alan,

We faced a similar issue during our EAD migration. We decided to create the
most-updated copy of the record externally to AS by combining legacy
records, deleting the AS record, and re-importing.  We matched on the
bibliographic ID, which is a stable unique identifier in the metadata in
every record. Our basic workflow was captured in Figure 1 here:
https://journal.code4lib.org/articles/14871 We were working in XML, but the
same method could be applied using the JSON record.  The advantage of doing
this is that there was no need to persist AS IDs.  This was possible in
part because we don't use the AS front-end to publish our finding aids, so
this didn't break any existing published links. I'd be happy to chat
offline if you think this approach would be worth exploring.
