"On Being a Hub: Some Details behind Providing Metadata for the Digital Public Library of America"

Posted in Digital Libraries, Metadata on July 16th, 2014

Lisa Gregory and Stephanie Williams have published "On Being a Hub: Some Details behind Providing Metadata for the Digital Public Library of America" in D-Lib Magazine.

Here's an excerpt:

After years of planning, the Digital Public Library of America (DPLA) launched in 2013. Institutions from around the United States contribute to the DPLA through regional "service hubs," entities that aggregate digital collections metadata for harvest by the DPLA. The North Carolina Digital Heritage Center has been one of these service hubs since the end of 2013. This article describes the technological side of being a service hub for the DPLA, from choosing metadata requirements and reviewing software, to the workflow used each month when providing hundreds of metadata feeds for DPLA harvest. The authors hope it will be of interest to those pursuing metadata aggregation, whether for the DPLA or for other purposes.

    Integrating Researcher Identifiers into University and Library Systems

    Posted in Metadata on May 13th, 2014

    CNI has released a video of the Integrating Researcher Identifiers into University and Library Systems session at the CNI spring 2014 meeting.

    Here's an excerpt from the announcement:

    A number of approaches to providing authoritative researcher identifiers have emerged, but they tend to be limited by discipline, affiliation or publisher. This talk provides an overview of an OCLC Research task group's analysis of a complex ecosystem of systems and institutions that provide, aggregate and use researcher and name authorities: researcher identifier systems. The presentation reflects on the state of the practice and on the remaining challenges to the integration of researcher identifiers into the systems and practices of libraries, universities, funders, and publishers.

      "PREMIS-Lite, a Preservation Metadata Generator"

      Posted in Digital Curation & Digital Preservation, Metadata on March 5th, 2014

      Todd P. Swanson has published "PREMIS-Lite, a Preservation Metadata Generator" in Library Philosophy and Practice

      Here's an excerpt:

      Using the PREMIS standard as a model this project creates a "PREMIS-Lite" xml preservation metadata generator. This PREMIS-Lite XML generator and its supporting PREMIS-Lite semantic unit definition, user guide, and crosswalk combine to allow for the simple capture and creation of preservation metadata at the object level.

        Open Discovery Initiative: Promoting Transparency in Discovery (Draft)

        Posted in Electronic Resources, Linking, Linked Data, and Semantic Web, Metadata on October 17th, 2013

        The National Information Standards Organization has released a draft of the Open Discovery Initiative: Promoting Transparency in Discovery.

        Here's an excerpt from the announcement:

        Launched in 2012, the NISO Open Discovery Initiative (ODI) aims to facilitate increased transparency in the content coverage of index-based discovery services and to recommend consistent methods of content exchange. This draft recommended practice provides specific guidelines for content providers on metadata elements, linking, and technical formats, and for discovery service providers on content listings, linking, file formats, methods of transfer, and usage statistics. The document also provides background information on the evolution of discovery and delivery technology and a standard set of terminology and definitions for this technology area.

          Dublin Core Metadata Initiative Releases DC-2013 Proceedings

          Posted in Digital Curation & Digital Preservation, Metadata on September 16th, 2013

          The Dublin Core Metadata Initiative has released the DC-2013 proceedings.

          Here's an excerpt from the conference description:

          DC-2013 will explore questions regarding the persistence, maintenance, and preservation of metadata and descriptive vocabularies. The need for stable representations and descriptions spans all sectors including cultural heritage and scientific data, eGovernment, finance and commerce. Thus, the maintenance and management of metadata is essential to address the long term availability of information of legal, cultural and economic value.

            "How Portable Are the Metadata Standards for Scientific Data? A Proposal for a Metadata Infrastructure"

            Posted in Data Curation, Open Data, and Research Data Management, Digital Curation & Digital Preservation, Metadata on September 10th, 2013

            Jian Qin and Kai Li have self-archived "How Portable Are the Metadata Standards for Scientific Data? A Proposal for a Metadata Infrastructure."

            Here's an excerpt:

            The one-covers-all approach in current metadata standards for scientific data has serious limitations in keeping up with the ever-growing data. This paper reports the findings from a survey to metadata standards in the scientific data domain and argues for the need for a metadata infrastructure. The survey collected 4400+ unique elements from 16 standards and categorized these elements into 9 categories. Findings from the data included that the highest counts of element occurred in the descriptive category and many of them overlapped with DC elements. This pattern also repeated in the elements co-occurred in different standards. A small number of semantically general elements appeared across the largest numbers of standards while the rest of the element co-occurrences formed a long tail with a wide range of specific semantics. The paper discussed implications of the findings in the context of metadata portability and infrastructure and pointed out that large, complex standards and widely varied naming practices are the major hurdles for building a metadata infrastructure.

              The Digital Preservation Coalition and Charles Beagrie Ltd have released the second edition of Preservation Metadata.

              Here's an excerpt from the announcement:

              The second edition of 'Preservation Metadata,' written by Brian Lavoie and Richard Gartner, focuses on new developments in preservation metadata, since the first edition of the report (published Sept 2005), made possible by the emergence of PREMIS as a de facto international standard.

                "Workflow Tools for Digital Curation"

                Posted in Digital Curation & Digital Preservation, Metadata on April 18th, 2013

                Andrew James Weidner and Daniel Gelaw Alemneh have published "Workflow Tools for Digital Curation" in the latest issue of the Code4Lib Journal.

                Here's an excerpt:

                Maintaining usable and sustainable digital collections requires a complex set of actions that address the many challenges at various stages of the digital object lifecycle. Digital curation activities enhance access and retrieval, maintain quality, add value, and facilitate use and re-use over time. Digital resource lifecycle management is becoming an increasingly important topic as digital curators actively explore software tools that perform metadata curation and file management tasks. Accordingly, the University of North Texas (UNT) Libraries develop tools and workflows that streamline production and quality assurance activities. This article demonstrates two open source software tools, AutoHotkey and Selenium IDE, which the UNT Digital Libraries Division has adopted for use during the pre-ingest and post-ingest stages of the digital resource lifecycle.
