Complete documentation of data attributes in Folio module APIs is needed to enable data modeling work as part of building reporting functionality. In particular, this is needed to ensure data quality for reporting.
The specific documentation requirements being requested are described in: https://issues.folio.org/browse/FOLIO-1551
This issue is a blocker for the entire Library Data Platform reference implementation epic ( https://issues.folio.org/browse/UXPROD-1128 ) . We may be able to develop somewhat in parallel; however, most of the documentation will be needed early in the reporting development because data models, ETL, and report queries all depend on it.
