PREMIS Data Dictionary 2.0

Original Data Dictionary released May 2005• “Frozen”: (no updates/changes) for an extended period• Allow Dictionary to circulate• Achieve critical mass of necessary revisions

Revision process: October 2006 – March 2008• Formation of Editorial Committee to manage revision• Based on accumulated feedback through many channels

(PIG list, conferences, tutorials, …) • Open process

March 2008: PREMIS 2.0 releasedhttp://www.loc.gov/standards/premis/v2/premis-2-0.pdf

PREMIS 2.0: Major changes

PREMIS Data Model:• Modified inter-entity relationships to be bi-directional;

simplifies model; more flexibility in recording relationships Rights entity:

• Modified to permit richer description of rights statements• Expanded to 3 forms of IPR: copyright, license, statute

Significant properties & preservation level:• Significant properties: structured description (facet/property)• Preservation level (intensity): why, when, what context

Extensibility:• Formal mechanism for extending PREMIS semantic units• Applied new “extension container” as semantic component for

seven PREMIS semantic units http://www.dlib.org/dlib/may08/lavoie/05lavoie.html

After the revision: PREMIS activities PREMIS & METS:

• Implementation Guidelines• Use of PREMIS in METS profiles (forthcoming)

Understanding PREMIS: Priscilla Caplan (2009):• Gentle introduction to the PREMIS standard• Spanish and Italian translations

PREMIS in D-Lib Magazine (2008):• PREMIS With a Fresh Coat of Paint• Battle of the Buzzwords: Flexibility vs. Interoperability when

Implementing PREMIS with METS• Using METS, PREMIS, and MODS for Archiving eJournals• Repository to Repository Transfer of Enriched Archival Information

Outreach: Tutorials in Berlin (Sept. 2008), Rome (Feb. 2009)

PREMIS conformance

Looking to the Future (circa 2006) Basic questions (“what type”, “how much”) still unsettled …

• Digital preservation processes still not fully tested/understood• Hard to judge effectiveness a priori• Important to document and share practical experience

Workflows for preservation metadata …• Tools to support automatic generation of preservation metadata (JHOVE, NLNZ

tools)• Tools should support formal metadata schemas (like PREMIS)• Registries (PRONOM, GDFR)

Harmonization with other initiatives …• Integrate PREMIS with other standards, technologies, best practices• E.g., Z39.87, METS• Not just standards, but integrated solutions

Division of labor …• Efficient strategies for collecting preservation metadata: i.e., WHO and WHEN

(Automatic Exposure project)

The State of PREMIS

de facto standard for preservation metadata

PREMIS implementations are appearing in many places, many contexts, many forms

Little consolidation of implementation experiences, issues, best practices, necessitating …

… a shift in focus from theory to practice, concepts to implementation, development to use
