DRAMBORA Tool Evaluation

The DRAMBORA toolkit document appears to me to be very thorough and well thought out, and the progressive steps of the audit process are straight forward. It makes sense to me to follow in sequence from identification of risks, to assessment of those risks and finally to the establishment of risk treatment strategies. I found the toolkit it to be an easy to follow and self-explanatory guide for auditing digital repositories. It seems also to be flexible enough to handle almost any repository. Further, I believe the concept of basing a repository audit on risk assessment principles to be ingenious. Why else would one audit a digital repository, if not to safeguard against any and all risks of loss of the usefulness of its information?

My praise should not be taken to suggest that all is well. At times, the process in DRAMBORA seems a bit redundant, and I suppose one could argue for a consolidation of some of the worksheets. Tasks 8, 9 and 10 come immediately to mind. Each of the final three worksheets repeats the preceding sheet’s information and then adds a new step. However, it is important to take things one step at a time in such an exercise as auditing a repository. By waiting to assess risks until all risks have been identified and logged, for instance, keeps one focused on the whole of the repository at the time of assessment. In this manner it seems much easier to keep perspective about the comparative impact of a single risk when assessment comes in an organized functional sequence. Ultimately, in my view, combining the identification, assessment and evaluation of risks into the same functional step is too much to deal with at once and may overwhelm an auditor.

There is some minor repetitiveness in some of the other worksheets as well, for example where repository objectives or mandates may include initiatives that address legal issues, such sources of information may be included in multiple worksheets. We found that the same information may be listed in worksheets 2, 3, and 4, for instance. In our group we decided to handle this repetitive entry by listing the same sources of information in multiple worksheets, as long as the focused perspective of each worksheet was the cause of listing the item.

The repetitive issues did not seem that significant to me, and certainly they were not so problematic that it interfered with or belabored our audit process.

I did not find the audit project particularly difficult, but it was rather laborious and tedious, which I suppose was to be expected for audit work. All of my working experience with audits, performing them and being the subject of them, tells me this is so. But, the step by step approach of DRAMBORA keeps everything organized and very simple to follow. In the end, I liked the toolkit document, and I think the approach is a good one.

There are some aspects of IDEALS that are somewhat inflexible because of its affiliation with a University. This is especially noteworthy in the face of severe budgetary confinements. A corporate repository may have different capabilities and freedoms to respond to audit findings, and in fact, may encompass an entirely different need for an audit in the first place. With limited abilities to respond to the audit findings, IDEALS may find itself in a position of foregoing action on certain recommendations. However, this should not preclude the repository from undertaking a thorough audit of its processes, obligations and risks. It is important to understand the risks and to take action where possible. Even if some glaring risks cannot be addressed, at least the repository management becomes aware of them and can anticipate needed future changes to eventually handle the potential risk. By bringing these risks to the attention of the University’s provost and other executive leadership, such leaders will not be caught off-guard about potentially substantial financial losses as a result of the occurrence of certain events.

In my opinion, the DRAMBORA approach works fine for IDEALS. I did not perceive any significant challenges employing the audit methods for this repository. The audit steps are not complicated nor are they restrictive in their application. This flexibility, I think, allows wide-spread applicability of DRAMBORA.

As to the DRAMBORA project being useful to me in terms of its educational value, I think of some other experiences that give me reason to say confidently that is was very supportive of excellent learning outcomes in this class. For instance, in March, I participated in the GSLIS’s alternative spring break program and spent a week at the Church History Library in Salt Lake City, Utah. I mostly did some job shadowing in five different departments at this brand new facility (opened in May 2009). My experience in the digital preservation department was very rewarding, as I observed ingest, migration, audit, and archiving of text, audio and visual digital objects, some born digital and others taken from analog documents. In class, we had just finished our grant proposals in which we constructed a workflow for a digital preservation project. As I sat with the manager of the DP department at CHL, he described the workflow that his staff follows every day, which was exactly what we had just written in the group assignment. He, as did we, used the OAIS document as the basis for the workflow.

I cite this experience for two reasons. First, it is only one, but perhaps the best, example that I have found everything we have done or discussed in this class has been right at the forefront of the digital preservation world. When I discuss the concepts and principles with DP professionals, those discussions have confirmed their pertinence to real world issues. Based on that track record, I have no doubt that DRAMBORA likewise has contributed significantly to my understanding of the digital preservation process.

Second, I mention the CHL experience because it, as well as the DRAMBORA project itself, is another example of how learning through experience is the best way to learn. My experience at CHL went a long way in transitioning my understanding of the information presented in class into to real and memorable experiences in my mind. I will remember what I learned about OAIS much better for having some hands-on experience with it in a digital preservation department.

In an article about the constructivist learning theory, Cooperstein and Kocevar-Weidinger point out that learning comes from experience, and not the other way around. So, the experience of DRAMBORA (among other things in this class) has contributed greatly to my education. If we were to simply talk and theorize about auditing repositories, some of us would show up for work one day and still not know how to perform an audit. Now that we have actually completed an audit, we will be more confident, capable, and prepared to do the next one.

For a first iteration of the risk assessment based audit method, I found DRAMBORA to be quite comprehensive, and yet, user-friendly. As an old insurance guy turned librarian, I noticed DRAMBORA’s adherence to the same risk management principles used by organizations, large and small, to manage their physical exposures to loss. With that in mind, I expect DRAMBORA will only get better as new iterations are released, revised according to experiences with the first and succeeding versions.

Notes from Risk Management of Digital Information: A File Format Investigation

· The most pressing problems confronting managers of digital collections are data format and software obsolescence.

· The concept of an information life cycle is emerging as a major theme in digital preservation, and as a model it provides some guidance on where risk-management efforts should be directed. In the abstract, a digital life cycle plans for the creation and stages of use of information and, ultimately, for whether the file will remain in a terminal, unchanging state or be transformed into another format for reuse. The choice of how or when to assess risk in the digital life cycle depends on circumstances, the state of the digital information, and the general preservation strategy adopted.

· A file format represents the arrangement of the structural and data elements in a unique and specific manner. In this context, migration is the process of rearranging the original sequence of structural and data elements (the source format) to conform to another configuration (the target format).

· An alternative preservation approach, emulation, is concerned with preserving the original software environment. Emulators are programs that mimic computer hardware. Strategies adopting this approach store copies of the initial software and descriptions of how to emulate the initial hardware to run the software along with the data files (Rothenberg 1999; 1995). Emulation has been practiced for many years, and there are several commercial and public domain emulators for a variety of hardware/operating system configurations. A good example is MS-DOS emulation in the Windows 95/98/ NT operating system.

· 1. John Bennett’s (1997) study evaluates preservation requirements by genre, format, media, and platform and uses a rudimentary risk-assessment scoring system. Displayed in a two-dimensional matrix, these requirements effectively communicate the complexity and interdependence of digital materials.

· 2. Haynes et al. (1997) reported on an in-depth investigation into the responsibilities associated with maintaining digital archives. This paper summarizes numerous interviews with focus groups and individuals and effectively communicates the range of opinions and expectations associated with different stakeholders.

· 3. The third work is the Reference Model for an Open Archival Information System (OAIS) (CCSDS 1999). The report is remarkable for its breadth and depth. In the authors’ words, the model they describe “provides a framework for the understanding and increased awareness of archival concepts needed for long-term digital information preservation and access, and for describing and comparing architectures and operations of existing and future archives.”

· 4. The last item is a report written by Ann Green, JoAnn Dionne, and Martin Dennis (1999). Their study describes a project at Yale to convert data from column binary to spread ASCII format. The nine-step data migration process is well documented, and the findings and recommendations clarify important preservation issues.

· We believe that three major categories of risk must be measured when considering migration as a digital strategy:

• Risks associated with the general collection. These risks include the presence or absence of institutional support, funding, system hardware and software, and the staff to manage the archive. These are essential components of a digital archive, which the Task Force on Archiving of Digital Information (1996) describes as “deep infrastructure.” The collection, and the stakeholders who use the collection, will be affected to some degree by a migration of data. Legal and policy issues associated with digital information will introduce additional risks.

• Risks associated with the data file format. These include the internal structural elements of the file that are subject to modification.

• Risks associated with a file format conversion process. The conversion software may or may not produce the intended result; conversion errors may be gross or subtle.

· See “Workbook Ideas” in Table 1 on page 7 (PDF pg. 13) for examples of risk categories. See Appendix A, pp. 18-43 (PDF pp. 24-49) for the complete workbook used n this study. Using a workbook format for risk analysis provides consistent guidance.

· Software programs that convert source formats into target formats are grouped into three general categories:

• Translation programs for a specific project written by a company, by the owner of the information, or by a third-party vendor. Data archives often write these programs at considerable cost. The CUL experience with locally developed software is described in the TIFF image file case study.

• A commercial translation program written for a specific purpose. For example, some products extract data fields from numerous files with different formats and create a new data product with a different format. Programs such as DataJunction are written specifically for this purpose.

• A general-purpose commercial translation program. Conversions Plus by DataVis is a good example of this growing genre of software.

· A format risk assessment has to explore two distinct areas of risk: the risk introduced by the conversion program and the magnitude of recurring risk inherent in a large collection. In addition, the features and usability of the conversion software should be considered as well as the impact on the metadata associated with the files.

Archival Theory & Diplomatics

Archival science encompasses the theory, methods, practice and analysis of the safe storage, cataloging and accession of materials. Its history has been primarily concerned with preservation and safe handling of documents as well as measuring and reporting the provenance of documents to assure their reliability and authenticity. With the advent of digital documents the science has taken on an expansion of each of its process parts. Duranti[i] and Gilliland-Swetland[ii] refer to an archival paradigm. Interestingly, the former suggests that the science has experienced a paradigm shift, where as the latter presents a strong case that the paradigm remains intact and has only taken on new opportunities. In this paper a few of their key thoughts will be discussed leading to a conclusion that semantics aside, the science has undergone significant evolution leading to the ultimate adoption of principles from multiple disciplines of information science to emerge as an all-encompassing system to support the proper archiving of documents, electronic and otherwise.

In Duranti’s description of archival science as a system, she proposes that all the system parts must function together (theory, methodology, practice, and scholarship) to achieve a clear objective. When one part of the system is changed, then the whole system can be considered changed. Galliland-Swetland identifies the newest iteration of the science’s functional requirements to be an amalgamation of process requirements from various disciplines (librarians, archivists, curators, preservationists, technical information specialists, and information systems and museum professionals) encouraging each community to be conversant with the practices and principles of each of the other communities. In the articles, each author in her own way is supporting the concept that archival science is dealing with more than mere information. It is a discipline and a profession that deals with knowledge. It is further posited that archivists should be engaged at the original development of knowledge and that engagement should carry on right through the long-range preservation of knowledge for future users. Archival science is preserving the story of knowledge development in order to save the context. Awareness and understanding of that context help to fully appreciate the knowledge and how it was created, and perhaps even its future uses. With that in mind, the sooner the archivist is brought into the process of knowledge creation and information handling, the better the preservation of that knowledge, since its ultimate storage and uses can be anticipated from the start.

The articles cite a number of studies and projects which have tackled the issues of collaboration between disciplines, specifically in confronting new challenges in dealing with electronic documents and their preservation. Several of those projects, such as the Preservation of the Integrity of Electronic Records research project at the University of British Columbia (UBC Project) and its follow-on project InterPARES (International Research on Permanent Authentic Records in Electronic Systems), set out to address the archivists’ challenges with records created or stored in electronic systems. These and other international committees and project teams, formulated in the late 1990’s and early 2000’s, studied specific digital document problems and made recommendations on how the archival science community should deal with and solve these new challenges. Duranti was a part of the two projects specifically mentioned here and edited the final reports and recommendations. The InterPARES project[iii] is important for many reasons, not the least being its decidedly international flavor and thus the encouragement of archivists around the world to adopt strategies and methodologies that will best preserve the world’s knowledge and the future knowledge that will be developed in new formats and environments. Galliland-Swetland reviews the experiences and contributions of these projects and many other contributors from the archival community. Their findings and recommendations for preserving the documentary heritage of records, regardless of their format, are presented and analyzed.

Further, it is suggested that projects undertaking the development of future electronic systems should acquire and maintain a vision of this integration of multiple disciplinary theories and methodologies. It is deemed important for the future of archival science to become a part of such development efforts. For example, on pages 24 and 25 of Galliland-Swetland’s report, the author poses several questions about metadata after stating the need for identifying the “tensions between the rich and complex metadata sets that individual communities have developed”. With more and more non-specialists using digital archives the need for simpler metadata sets seems apparent. An example or two of real case implementations as a response to this need are described by the author. The first cited case is the use of a new archival descriptive standard in the United States called Encoded Archival Description (EAD), which can be a more flexible metadata infrastructure, and which is capable of supporting information retrieval and display without compromising any archival objectives. The second example given is SPIRT, a recordkeeping metadata standards project conducted in Australia. SPIRT has had success in integrating standardized metadata schemes into record keeping systems and retaining support of archival uses as well.

Based on the evidence of such cases and the findings of the reports in general, the authors suggest that archival science must become more collaborative now and in the future than it has been in the past in order to more fully inculcate the theories and practices of archival science into the process of knowledge creation and long-range handling of knowledge documents and document storage. Some questions to consider for class discussion are:

1) Why hasn’t there been more collaboration in the past? What is it about electronic documents or the current environment that suddenly caused awareness of this need, or at least willingness to address it?

2) How best can archivists approach this challenge and garner the invitation to be involved in the knowledge creation process at the outset, instead of when it may be too late? How can a more holistic view be instilled in all knowledge and information workers to enable adoption of the collaboration principles espoused by the Galiland-Swetland and Duranti articles and reports?

3) Who will be best positioned to bring the various disciplines together, especially those outside the realm of information science (i.e. computer science)? Will it be archival scientists, computer scientists, or some other group?

Taken together, these articles provide an outline of a number of steps that, to some extent at least, have already been implemented and that should be widely adopted in order to continue the evolving process of establishing guidelines and rules for the work of archivists when dealing with all types of documents, including the newest formats and those yet to be developed.

The goals of the projects and committees cited in the articles include a refinement of the archival rules and models so as to eliminate duplication and to bring into the field many good practices, theories and models from other disciplines that strengthen the archival process. The system of archival science needs the adoption of outside models and theories to enrich and modernize its own processes. The other disciplines are also enhanced when their theories and methodologies adopt a keen awareness of the principles of archival science. In this way, the archival principles of reliability, authenticity, provenance and transparency are maintained in a changing environment that continually introduces new knowledge creation technologies and also produces new document formats.
