  5. Processes for archiving and disposal 8. Archiving and disposal 8.1 Manage archive repository • define archival format, format data, load data, record event dates, links to metadata registry (IMDB) 8.2 Preserve data and associated metadata • Identify data/metadata, record archive request, transfer data/metadata, etc. 8.3 Dispose data and associated metadata • Identify data to dispose, remove from archive, etc.
