    Preserving Computer-Aided Design (CAD)

    Posted in Data Curation, Open Data, and Research Data Management, Digital Curation & Digital Preservation, Reports and White Papers on July 25th, 2013

    The Digital Preservation Coalition has released Preserving Computer-Aided Design (CAD).

    Here's an excerpt:

    Computer-Aided Design (CAD) systems are used in both industry and academia to create digital models, whether of engineering designs, archaeological dig sites, or virtual worlds. These models can be of long-lasting significance and importance, particularly if they contain irreplaceable data or relate to long-lived products. This report is primarily aimed at those responsible for archives and repositories with CAD content, but may also be useful for creators of CAD content who want to make their models more amenable to preservation. It begins with an introduction to the historical development and basic concepts of CAD systems, then reviews the most pertinent issues associated with preserving CAD models, and indicates the current state of standardization work in the area. The report goes on to present some recent research of relevance to preserving CAD models before drawing conclusions and making recommendations on how archives should handle the CAD models they accept.

      "An Evaluation of Caching Policies for Memento TimeMaps"

      Posted in Digital Curation & Digital Preservation on July 24th, 2013

      Justin F. Brunelle and Michael L. Nelson have self-archived "An Evaluation of Caching Policies for Memento TimeMaps" in arXiv.org.

      Here's an excerpt from :

      As defined by the Memento Framework, TimeMaps are machine-readable lists of time-specific copies—called "mementos"—of an archived original resource. In theory, as an archive acquires additional mementos over time, a TimeMap should be monotonically increasing. However, there are reasons why the number of mementos in a TimeMap would decrease, for example: archival redaction of some or all of the mementos, archival restructuring, and transient errors on the part of one or more archives. We study TimeMaps for 4,000 original resources over a three month period, note their change patterns, and develop a caching algorithm for TimeMaps suitable for a reverse proxy in front of a Memento aggregator. We show that TimeMap cardinality is constant or monotonically increasing for 80.2% of all TimeMap downloads observed in the observation period. The goal of the caching algorithm is to exploit the ideally monotonically increasing nature of TimeMaps and not cache responses with fewer mementos than the already cached TimeMap. This new caching algorithm uses conditional cache replacement and a Time To Live (TTL) value to ensure the user has access to the most complete TimeMap available. Based on our empirical data, a TTL of 15 days will minimize the number of mementos missed by users, and minimize the load on archives contributing to TimeMaps.

            "Crafting Linked Open Data for Cultural Heritage: Mapping and Curation Tools for the Linked Jazz Project"

            Posted in Digital Archives and Special Collections, Digital Curation & Digital Preservation, Linking, Linked Data, and Semantic Web on July 19th, 2013

            M. Cristina Pattuelli, Matt Miller, Leanora Lange, Sean Fitzell, and Carolyn Li-Madeo have published "Crafting Linked Open Data for Cultural Heritage: Mapping and Curation Tools for the Linked Jazz Project" in the latest issue of Code4Lib Journal.

            Here's an excerpt:

            This paper describes tools and methods developed as part of Linked Jazz, a project that uses Linked Open Data (LOD) to reveal personal and professional relationships among jazz musicians based on interviews from jazz archives. The overarching aim of Linked Jazz is to explore the possibilities offered by LOD to enhance the visibility of cultural heritage materials and enrich the semantics that describe them. While the full Linked Jazz dataset is still under development, this paper presents two applications that have laid the foundation for the creation of this dataset: the Mapping and Curator Tool, and the Transcript Analyzer. These applications have served primarily for data preparation, analysis, and curation and are representative of the types of tools and methods needed to craft linked data from digital content available on the web. This paper discusses these two domain-agnostic tools developed to create LOD from digital textual documents and offers insight into the process behind the creation of LOD in general.

              "Batch Metadata Assignment to Archival Photograph Collections Using Facial Recognition Software"

              Posted in Digital Archives and Special Collections, Digital Curation & Digital Preservation on July 19th, 2013

              Kyle Banerjee and Maija Anderson have published "Batch Metadata Assignment to Archival Photograph Collections Using Facial Recognition Software" in the latest issue of Code4Lib Journal.

              Here's an excerpt:

              Useful metadata is essential to giving individual meaning and value within the context of a greater image collection as well as making them more discoverable. However, often little information is available about the photos themselves, so adding consistent metadata to large collections of digital and digitized photographs is a time consuming process requiring highly experienced staff.

              By using facial recognition software, staff can identify individuals more quickly and reliably. Knowledge of individuals in photos helps staff determine when and where photos are taken and also improves understanding of the subject matter.

              This article demonstrates simple techniques for using facial recognition software and command line tools to assign, modify, and read metadata for large archival photograph collections.

                  "Using Data Curation Profiles to Design the Datastar Dataset Registry"

                  Posted in Data Curation, Open Data, and Research Data Management, Digital Curation & Digital Preservation on July 16th, 2013

                  Sarah J. Wright, Wendy A. Kozlowski, Dianne Dietrich, Huda J. Khan, and Gail S. Steinhart have published "Using Data Curation Profiles to Design the Datastar Dataset Registry" in the latest issue of D-Lib Magazine.

                  Here's an excerpt:

                  The development of research data services in academic libraries is a topic of concern to many. Cornell University Library's efforts in this area include the Datastar research data registry project. In order to ensure that Datastar development decisions were driven by real user needs, we interviewed researchers and created Data Curation Profiles (DCPs). Researchers supported providing public descriptions of their datasets; attitudes toward dataset citation, provenance, versioning, and domain specific standards for metadata also helped to guide development. These findings, as well as considerations for the use of this particular method for developing research data services in libraries are discussed in detail.

                    "Foundations of Data Curation: The Pedagogy and Practice of "Purposeful Work" with Research Data"

                    Posted in Data Curation, Open Data, and Research Data Management, Digital Archives and Special Collections, Digital Curation & Digital Preservation on July 15th, 2013

                    Carole L. Palmer, Nicholas M. Weber, Trevor Muñoz, and Allen H. Renear have punlished "Foundations of Data Curation: The Pedagogy and Practice of "Purposeful Work" with Research Data" in the latest issue of Archive Journal.

                    Here's an excerpt:

                    Increased interest in large-scale, publicly accessible data collections has made data curation critical to the management, preservation, and improvement of research data in the social and natural sciences, as well as the humanities. This paper explicates an approach to data curation education that integrates traditional notions of curation with principles and expertise from library, archival, and computer science. We begin by tracing the emergence of data curation as both a concept and a field of practice related to, but distinct from, both digital curation and data stewardship. This historical account, while far from definitive, considers perspectives from both the sciences and the humanities. Alongside traditional LIS and archival science practices, unique aspects of curation have informed our concept of "purposeful work" with data and, in turn, our pedagogical approach to data curation for the sciences and the humanities.
