Parking lot for the Holdings/MARC working group

Here the Holdings MARC mapping WG will gather misc. examples, use cases and ideas, which we need to circle back to at a later point:

1. What if a library wants to edit data in the Inventory Holdings instead of the MARC Holdings, since it will be simpler in Inv Holdings? If it's a 1:1 mapping between the Inv Holding and MARC Holding, could Inv Holding update the Source Record Storage MARC Holding, instead of having to update the SRS MARC Holding via MARCcat or Data Import? Probably needs a discussion at larger MM SIG; likely would need to wait until post-v1. (Lisa-TAMU, Dennis-Duke)
