BOF session on use of PREMIS with METS at Fall Forum in Boston Thursday, Nov. 9, 4:15-5:15pm (Fairmont Copley Plaza Hotel) The PREMIS Working Group released the Data Dictionary for Preservation Metadata (PREMIS) and its supporting 5 XML schema in May 2005, which defines and describes an implementable set of core preservation metadata with broad applicability to digital preservation repositories. A number of institutions have begun planning for implementations of preservation metadata in their digital repositories using PREMIS. Because of the flexibility of the METS schema and the PREMIS schemas, there is a need for the PREMIS community to develop best practices for using PREMIS within METS documents. This BOF will explore some of the approaches that implementors are taking in regard to using PREMIS with METS. These include a number of issues that are detailed below; it is suggested that attendees consider these issues in terms of the way their institutions are approaching them. The broader question of the types of events that institutions want to track and how event outcomes should be recorded will also be considered. It is hoped that the results of this session will lead to proposals for best practices. Using PREMIS and METS together: issues 1. Which METS sections are you using for which PREMIS entities? 2. Are you repeating the main METS sections (e.g. amdSec, digiProv) and what guides the repetition? 3. Should elements that are in both PREMIS and METS be recorded redundantly or only in one or the other (e.g. size, checksum)? 4. How do you record elements that are in PREMIS as well as a format specific metadata schema (e.g. MIX)? Redundantly or in one or the other? 5. How do you record structural relationships? The METS structMap covers this to some extent, but there are also PREMIS relationship elements that do the same. 6. How do you deal with controlled vocabularies? PREMIS suggests using them in many places, but they are not enumerated in the schema and thus cannot be controlled/validated. What further work needs to be done? 7. Are you using the PREMIS container schema or the other 4 schema separately without the PREMIS wrapper (i.e. object, event, rights, agent)? Event issues 1. What types of events are you tracking? 2. How are you controlling event type values? 3. What are you recording in eventOutcome and/or eventOutcomeDetail? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^ Rebecca S.
