The 2023 iPres conference at the University of Illinois in Champaign-Urbana brought an international community of digital archivists to the Midwest for a week of sessions that explored a range of digital preservation challenges.

In the UMich Research Data Services (RDS) group, we see and work with all sorts of data. One particularly thorny variety is netCDF. In Deep Blue Data, we have been getting regular deposits of data in this format, and we didn't know much about it. We had many questions how do we open it, what's its structure, how do researchers create these files and why can the size vary so widely from 100s of MBs to 100s of GBs or even TBs? Jake Carlson, Director of RDS, and I hashed out the idea of creating "profiles" for file formats as quick reference resources for RDS as well as others in the data curation field to help us do our jobs more easily and consistently. So, we thought we'd pilot this idea by creating a “Data Curation Format Profile” (DCFP) for netCDF data files since it seemed like an interesting file format and we were likely to get more of them in the future.
