Metadata Workflows Across Research Domains: Challenges and Opportunities for Supporting the DFC Cyberinfrastructure
No full textThis poster presents research results from a recent survey studying metadata workflows. The survey was distributed to DataNet Federation Consortium researchers and collaborators asking participants about their organizational practices involving metadata creation. Data management best practices recommend that data documentation happens at the very beginning of the research project, before data collection. However, these results indicate that more scientific metadata is created during or after the data collection process than before, and that few researchers take advantage of automated metadata generation workflows. Data curators, librarians, and archivists (or their automated systems) can assist researchers by intervening earlier in the data life cycle in order to produce higher-quality metadata and ensure long-term preservation
Metadata Integration for an Archaeology Collection Architecture
Get PDFCurrent trends in data collections are moving toward infrastructure services that are centralized, flexible, and involve diverse technologies across which multiple researchers conduct simultaneous, parallel workflows. During the lifecycle of a project, from the collection of raw data through study to publication, researchers remain active curators and decide how to present their data so others can access and reuse it. In this context, metadata is key to ensuring that data and results remain organized and secure, but building and maintaining metadata can be cumbersome, especially in the case of large and complex datasets. This paper presents our work to develop a complex collection architecture with metadata at its core, for a large and varied archaeological collection. We use metadata, mapped to Dublin Core, to tie the pieces of this architecture together and to manage data objects as they move through the research lifecycle over time and across technologies and changing methods. This metadata, extracted automatically where possible, also fulfills a fundamental preservation role in case any part of the architecture should fail
The ARK Identifier Scheme: Lessons Learnt at the BnF and Questions Yet Unanswered
No full textThe Bibliothèque nationale de France (BnF) looks back at lessons learnt over a decade of implementing persistent identifiers (ARKs). Those lessons give an insight into what it means to maintain persistent identifiers in the mid-term. A systematic gap analysis between what is and what should be, especially in a Semantic Web context, lead to open questions about best practices and standards compliance
Interlinking Cross Language Metadata Using Heterogeneous Graphs and Wikipedia
No full textCross-language metadata are essential in helping users overcome language barrier in information discovery and recommendation. The construction of cross-language vocabulary, however, is usually costly and intellectually laborious. This paper addresses these problems by proposing a Cross-Language Metadata Network (CLMN) approach, which uses Wikipedia as the intermediary for cross-language metadata linking. We conducted an experiment with key metadata in two digital libraries and in two different languages without using machine translation. The experiment result is encouraging and suggests that the CLMN approach has the potential not only to interlink metadata in different languages with reasonable rate of precision and quality but also to construct cross-language metadata vocabulary. Limitations and further research are also discussed
Embedded Metadata -- A Tool for Digital Excavation
No full textIn June of 2012, I began the weighty task of searching the far reaches of Phoenix Art Museum's digital storage spaces to import images into a recently acquired collection management system, The Museum System (TMS). I excavated long forgotten folders on various servers and desktops, hunting for visual documentation of the art collection and past installations. Embedded metadata was used as a tool to identify images of art objects and indicate which folders and files had been searched. These assets were then reorganized with a new file and folder structure. A custom XML panel, developed by the Visual Resource Association Embedded Metadata Working Group, provided a pre-established controlled vocabulary that adheres to Dublin Core and VRA core guidelines. This tool combined with tools offered by Adobe Bridge, such as batch metadata editing and file renaming greatly increased my workflow and the quality of my data. After my initial survey over five months, I was able to import about 10,000 files into TMS, which is a 280% increase from the files imported into the previous collection management system. This poster will discuss my method for using embedded metadata to track information about digital assets as well as challenges and opportunities for further development. This method could be implemented by other cultural organizations as a low cost approach to tracking basic metadata, content creators and copyright restrictions
Applying a linked data compliant model: The usage of the Europeana Data Model by the Deutsche Digitale Bibliothek
No full textIn 2013/14 the Deutsche Digitale Bibliothek (DDB) switched its data model from the CIDOC conceptual reference model to the Europeana Data Model (EDM). This decision was taken on the background of two major mandates the DDB has to fulfill: The DDB is as a portal and a platform providing access to digital objects from German cultural heritage and research institutions. On the other hand the DDB aims to become the German aggregator for Europeana. Using EDM as the internal DDB data model was approved as the most reasonable solution to meet these challenges. The DDB uses the model for all portal functions that require semantic links between metadata (search facets, hierarchies, links between authority files and digital objects). The application of EDM for the DDB portal raised some difficulties since not all necessary classes and properties were entirely implemented in Europeana-EDM at that time. Therefore, a DDB-EDM application profile was developed. The DDB publishes metadata under the CC0 Public Domain Dedication license in EDM-RDF/XML via an OAI-PMH interface to serve Europeana and also via an Application Programming Interface (API) for external users to develop new applications on the basis of metadata harmonized by the DDB
"Lo-Fi to Hi-Fi": A New Metadata Approach in the Third World with the eGranary Digital Library
No full textDigital information can bridge age-old gaps in access to information in traditionally underserved areas of the world. However, for those unfamiliar with abundant e-resources, their early exposure to the digital world can be like "drinking from a fire hose." For these audiences, abundant metadata and findability, along with easy-to-use interfaces, are key to their early success and adoption. To hasten the creation of metadata and user interfaces, the authors are experimenting with "crowd cataloging." This report documents their work and Maron's Lo-Fi to Hi-Fi metadata pyramid model guiding a developing metadata initiative being pursued with the eGranary Digital Library, the technology used by Widernet in a global effort to ameliorate information poverty. The Lo-Fi to Hi-Fi model, with principles adapted from technical design processes, aligns with research that has shown that community-based librarians are better poised to identify culturally congruent resources, but many require significant training in metadata concepts and skills. The model has students crowdsource "lo-fi" terms, which domain experts and information professionals can curate and cull in "hi-fi" to enhance findability of resources within the eGranary while simultaneously honing their own computer, information and metadata literacies. Though the focus here is on Africa, the findings and practices can be universalized to eGranaries around the globe, if successful
Automated Enhancement of Controlled Vocabularies: Upgrading Legacy Metadata in CONTENTdm
No full textTo ensure robust, reliable, retrievable and sharable metadata, the University of Houston (UH) Libraries initiated a Metadata Upgrade Project in 2013 to systematically audit and refine the quality of the metadata in the University of Houston Digital Library (UHDL). Still in progress, the Metadata Upgrade project has already produced significant improvements in the UHDL's legacy metadata. The final phase of the Metadata Upgrade Project includes aligning controlled vocabulary terms with appropriate authorities and adding and revising descriptive content in the digital library. This is a time intensive process that requires careful evaluation and entry of name and subject authority terms. To improve efficiency and accuracy during the data entry process, the metadata librarian at UH Libraries developed name and subject authority applications that automatically transform legacy controlled vocabulary terms into authorized forms. This project report will provide an overview of the University of Houston's Metadata Upgrade Project, a discussion of how the UHDL's upgraded metadata improves discoverability of our collections, and an in-depth look at the custom tools that automate the authority alignment process in the CONTENTdm Project Client
The Digital Public Library of America Ingestion Ecosystem: Lessons Learned After One Year of Large-Scale Collaborative Metadata Aggregation
No full textThe Digital Public Library of America (DPLA) aggregates metadata for cultural heritage materials from 20 direct partners, or Hubs, across the United States. While the initial build-out of our infrastructure used a lightweight ingestion system that was ultimately pushed into production, a year’s experience has allowed DPLA and its partners to identify limitations in that system, the quality and scalability of metadata remediation and enhancement possible, and areas for collaboration and leadership across the partnership. Although improved infrastructure is needed to support aggregation at this scale and complexity, ultimately DPLA needs to balance responsibilities across the partnership and establish a strong community that shares ownership of the aggregation process
DC Metadata is Alive and Well (and has Influenced a New Standard for Education)
No full textThe Dublin Core Metadata Initiative [DCMI], as a community, has collaboratively
developed 'standards' for twenty years. DCMI recommendations have become 'international standards'
by being adopted, for example by the United States' National Information Standards Organization [NISO],
and then by promotion by them to the International Standards Organization, [ISO/IEC JTC1]. This has led
to wider implementation on one dimension, formally, still shepherded by the DCMI. Different dimensions
have emerged from significant developments within other entities and communities, such as the World Wide
Web Consortium [W3C], etc. The deliberately open nature of DCMI work has meant that people with no known
connection to DCMI can nevertheless take advantage of the DCMI work. Further, it asserts that 'DC Metadata'
is, as a result of work done by outsiders, in fact thriving in the global environment
