PREMIS Implementation Fair 2012

An iPRES 2012 workshop sponsored by the PREMIS Editorial Committee, Open Planets Foundation and OCLC Research

Tuesday, October 2, 2012, University of Toronto, Canada

Links to presentations and notes from the event are available below.

You are invited to participate in the PREMIS Implementation Fair, a workshop held in association with the 9th International Conference on Preservation of Digital Objects (iPRES2012) in Toronto.  This workshop has two sessions: the first discusses PREMIS Implementation activities and the second will be devoted to exploring the use of real life preservation metadata for risk assessment in conjunction with a pilot conducted by the Open Planets Foundation and OCLC.The Implementation Fair will be an opportunity to:

  • give implementers of the PREMIS Data Dictionary for Preservation Metadata [PDF:1.1MB/184pp.] an opportunity to meet with one another and discuss implementation issues;
  • inform the community of implementers of the latest PREMIS updates, tools, and Editorial Committee activities;
  • share information about projects, problems and solutions.


Part 1: PREMIS Implementation Activities

9:00-9:15: Update on PREMIS activities [PDF]. Rebecca Guenther (Library of Congress) will give a brief overview of PREMIS activities since the last PREMIS Implementation Fair in Oct. 2010.

9:15-10:00: Changes in the PREMIS Data Model [PDF]. The next version of the PREMIS Data Dictionary will include a change in its data model to consider Environment a separate entity that has its own properties.  In addition, the revised data model will consider intellectual entities another level of a PREMIS object. Angela Dappert (Digital Preservation Coalition) will be describe this modeling work.

10:00-10:20: Changes for preservation rights metadata [PDF]. Robin Wendler (Harvard University) will describe the changes to the PREMIS Rights entity made in recently released PREMIS version 2.2 to include additional rights structures for rights and permissions in preservation repositories. The scope of these changes and how they are used will be discussed.

10:20-10:35: Break

10:35-11:15 Repository software. A number of repository software tools, both open source and commercial, are available that support preservation metadata. Included will be DAITSS, Archivematica, and ExLibris’ Rosetta. Priscilla Caplan [PDF] (Florida Center for Library Automation); Peter van Garderen [PDF] (Archivematica); Andrew French [PDF](ExLibris).

11:15-11:40 PREMIS OWL ontology [PDF]. Work has been progressing on establishing an ontology for PREMIS that is compatible with Linked Data and the Semantic Web. Sébastien Peyrard (Bibliothèque Nationale de France) will discuss this OWL ontology, which allows one to express the same information in RDF as can be expressed using the PREMIS XML schema. With this alternative serialization, information can be more easily interconnected, especially between different repository databases.

11:40-12:30 Implementations. Specific PREMIS implementations will be reviewed. Contributions will be solicited from implementers. If you would like to present on a topic or project, please contact us. Contributors: Lynn Benson [PDF] (National Library of New Zealand); Kyle Rimkus [PDF] (University of Illinois); Mark Evans [PDF] (Tessella).

12:30-1:30: Lunch

Part 2: Preservation Health Check

Joint OPF and OCLC Research workshop.
The Preservation Health Check Pilot is a new initiative by OCLC Research and the Open Planets Foundation that examines the use of preservation metadata as an evidence base for risk assessment in digital repositories tasked with the responsibility for long-term preservation. The PHC project will create a mapping between the PREMIS Data Dictionary and the new Simple Property-Oriented Threat (SPOT) Model, and demonstrate how this mapping can be implemented in real-world metadata to support evidence-driven risk assessment. The project will work with preservation metadata supplied by several participating institutions.

1:30–1:50: Welcome and introduction to the PHC-pilot [PDF]
Titia van der Werf (OCLC Research) will provide an introduction to the OCLC Research/Open Planets Foundation Preservation Health Check (PHC) Pilot, a new initiative examining the use of preservation metadata as an evidence base for risk assessment in digital repositories. She will discuss the project’s goals, approach, participating pilot sites, and anticipated impact.

1:50-2:20: Standards, Risk analysis, Common sense and Evidence [PDF]
Drawing on his background in Total Quality Management and experience with the Open Planets Foundation community of practice, Bram van der Werf (Open Planets Foundation) will discuss the thinking behind the PHC pilot and the necessity to bridge the gap between standardization and modeling efforts on the one hand, and evidence-based assessment and improvement of real life digital preservation practices on the other.

2:20–2:30 Presentation by BNF, one of the PHC-pilot sites [PDF]
Sébastien Peyrard (Bibliotheque Nationale de France) will explain why BNF is participating as a pilot site in the PHC pilot, and the benefits BNF hope to derive from it.

2:30–2:45 Break

2:45–3:00: Presenting the SPOT Model
Priscilla Caplan (Florida Center for Library Automation) will explain the Simple Property-Oriented Threat (SPOT) Model, which the PHC is using as part of its risk assessment methodology. Priscilla is a co-author of the SPOT Model.

3:00–3:45: Mapping preservation metadata to risk factors
Brian Lavoie (OCLC Research), who has worked on the development of the PREMIS Data Dictionary and on risk assessment modeling (SPOT Model), will discuss mapping preservation metadata to risk factors in the context of PREMIS and SPOT. He will discuss some sample mappings and their use in a risk assessment context.

3:45–4:45 Plenary Discussion
This session will be used for open discussion of the PHC pilot. In addition, workshop participants are invited to share their own experiences in regard to preservation metadata and risk assessment: what types of preservation metadata do they record? Is this metadata currently being used to support risk assessment? What are the key gaps between the preservation metadata currently being recorded and the metadata needed to support risk assessment in digital repositories?   

4:45–5:00 Wrap-up (Titia van der Werf)

Notes [PDF] from the PREMIS Implementation Fair are available.

Who should attend:
Digital preservation practitioners: digital librarians and archivists, digital curators, repository managers and those with a responsibility for or an interest in preservation workflows and systems.

Digital preservation researchers/experts: those who have been involved in research and/or standardization activities on preservation metadata implementation, metadata scheme development and modeling risk assessment frameworks.

To register please go to the iPres 2012 registration page. Attendance will be limited to 50 participants.
