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?
