  4. METS uses • The OAIS Model • Archival IP - long term preservation • Submission IP- what we’ve been trying to model • Dissemination IP- sent to end users

  5. Builder data entry Blue terms are used to select separate data entry screens entry screen Example of data

  6. OUTCOME ONE: VIRTUAL DIGITAL OBJECT The fileGrp segment of a METS instance “binds” the object Includes logical pathnames for files, future switch to persistent names possible.

  10. METS distributed data model • Success with simple objects compiled from several sources • MAVIS will supply source metadata and possibly more • Use of METS profiles – a templating feature of METS • NBC Radio, 78’s projects during 2004

  11. What’s Next? • Direct support of METS in MAVIS? • How to represent the n-tiered METS structmap? • What metadata do we really want to keep? • How are digital objects and their metadata stored for access and for long-term preservation
