Digital Preservation

Requirements and technical best practices for digital preservation functionality will be listed here.

4. Identify key preservation events/actions and outcomes for the repository to perform and record (e.g. PREMIS ingest, validation, migration, deletion, message digest calculation, fixity check, virus check) 

5. Identify storage requirements (e.g. number of copies, file access scenarios); consult with technology group regarding implementation. 

6. Evaluate and recommend use and configuration of characterization and validation tools; file format registries 

7. Review/contribute to preservation and technical metadata specs produced by Metadata Working Group
