Howdy, Charlotte.
Yesterday at the SysOps Data Migration Subgroup we discussed a mapping file that Theodor Tolstoy had put together as an initial map of Sierra item record elements to FOLIO item.json. We had some questions on how certain data elements in the FOLIO item were intended to be used. Theodor said he'd send his output to you to get comments on those issues.
I volunteered to create a similar item record mapping for Voyager item records, with similar questions. If you would like to look at it, it's available under this folder:
https://drive.google.com/open?id=1XAz6VByU4OArXOJvySrAb_XonzUdsJIL The full path is: OLF_Shared/FOLIO/Sys_Ops_Mgmt_SIG/Data_MIgration_Subgroup/voyager_data_maps
I think we'd be looking for comments in 2 areas: 1) answers to specific questions in the maps on how certain data elements are intended to be used; 2) your reaction to the general layout of the map. This is a much more linear, rationalized version than my first attempt at user records.
