TL;DR: This paper describes the methodological steps required to build an ontology to support the evolving knowledge representation requirements of the Linked Jazz project, an LOD project in the performing arts.
Abstract: In this paper we discuss the process of creating ontologies in the rapidly expanding Linked Open Data (LOD) landscape. Over the years the notion of applied ontologies has shifted from that of a knowledge-intensive conceptual model for closed system applications to that of a lightweight representation tool for an open and decentralized environment like the Web. New opportunities for sharing, reusing, and exploiting LOD ontologies available on the Web also bring new challenges for their development. Within the application scenario offered by Linked Jazz, an LOD project in the performing arts, we describe the methodological steps required to build an ontology to support the evolving knowledge representation requirements of the project.

TL;DR: The goal of this paper is to share with the readers the challenges faced by the University of Nevada, Las Vegas (UNLV) LOD project team in implementing the transformation of digital-collection metadata into LOD and the solutions that were adopted.
Abstract: Linked Open Data (LOD) has been a focus of great interest in the library and information science literature in recent years. Much of the literature in this area has been in explaining concepts and discussing its applicability to library data. Implementation of LOD is based on concepts that differ from those of more traditional databases and records. This adds a certain level of complexity to an understanding of its application in practice. As a relatively new topic, the library literature lacks best practices for implementing LOD. The goal of this paper is to share with the readers the challenges faced by the University of Nevada, Las Vegas (UNLV) LOD project team in implementing the transformation of digital-collection metadata into LOD and the solutions that were adopted. The author briefly introduces basic concepts of LOD and explains, step-by-step, how to transform digital-collections metadata into LOD, thereby indicating the open source technologies and data model that might be considered as tools fo...

TL;DR: A pilot project at the George Washington University Libraries to embed URIs into the local integrated library system and the toolset, MARCNext, which was utilized to simplify the entification of the Libraries’ legacy metadata records is discussed.
Abstract: While the future of library bibliographic description is currently in a state of flux, libraries have a number of opportunities to begin embedding and leveraging linked data concepts within their existing MARC-centric systems. Through the embedding of dereferenceable Uniform Resource Identifiers (URIs) into existing MARC data, libraries can begin to lay the foundation for the eventual shift to a data model that is more linked data friendly and begin to produce actionable metadata for consumption by services outside of the library community. This article will discuss a pilot project at the George Washington University Libraries to embed URIs into the local integrated library system and the toolset, MARCNext, which was utilized to simplify the entification of the Libraries’ legacy metadata records.

TL;DR: A case study of controlled vocabulary cleanup with practical advice on managing the cost of data cleanup while leveraging the value added and benefits gained through the process is presented.
Abstract: Linked open data is poised to fundamentally change metadata design and development and specifically has important implications for controlled vocabularies. In particular, Person/Agent vocabularies are key to linking data, but present complex issues in verification and maintenance. For linked open data to be more widely adopted, practical approaches to data management and transitioning from metadata to triples needs to be explored in detail. This paper presents a case study of controlled vocabulary cleanup with practical advice on managing the cost of data cleanup while leveraging the value added and benefits gained through the process.

TL;DR: The journey from exploration of how best to enter the world of the Semantic Web to the launch of the Getty vocabularies as LOD is described.
Abstract: In the summer of 2013, as part of the J. Paul Getty Trust's ongoing effort to make its knowledge resources freely available to all, a commitment was made to release the Getty vocabularies as Linked Open Data (LOD). The Art & Architecture Thesaurus was published as LOD in February 2014, followed by the Getty Thesaurus of Geographic Names in August 2014, and the Union List of Artist Names in April 2015. This article describes the journey from exploration of how best to enter the world of the Semantic Web to the launch of the Getty vocabularies as LOD.

TL;DR: A major data-cleanup project utilizing multiple approaches including a vendor's authority control service, data reconciliation in OpenRefine, and the exploration of different tools used for the creation and maintenance of local controlled vocabularies.
Abstract: The use of controlled vocabularies is essential in the creation of metadata for digital collections in order to provide consistency and ease of use for patrons and researchers. The University of Utah has been working to clean up metadata for digital collections to ensure that data adheres to best practices with the use of specific, controlled vocabularies. This has included a major data-cleanup project utilizing multiple approaches including a vendor's authority control service, data reconciliation in OpenRefine, and the exploration of different tools used for the creation and maintenance of local controlled vocabularies.

TL;DR: The researcher employed a descriptive content analysis methodology and examined 146 entry-level position announcements posted from September 2000 through August 2013 to describe substance and form characteristics examined in the position announcements and to make inferences to the community of catalog librarian practitioners.
Abstract: The emergence of metadata schema and implementation of Resource Description and Access changed the technical services workplace environment and demands increased regarding complex education requirements for metadata librarians and catalogers across the country. The proliferation of bibliographic description formats required practitioners to pursue extensive training and professional development opportunities. The researcher employed a descriptive content analysis methodology and examined 146 entry-level position announcements posted from September 2000 through August 2013. Conducting a descriptive content analysis enabled the researcher to describe substance and form characteristics examined in the position announcements and to make inferences to the community of catalog librarian practitioners.

TL;DR: The management of vocabularies in the evolving linked data environment requires different tools and processes from those libraries and other memory institutions have used in the past, including the rationale for directions, decisions, and ongoing development.
Abstract: The management of vocabularies in the evolving linked data environment requires different tools and processes from those libraries and other memory institutions have used in the past. The RDA (Resource Description and Access) standard has taken the lead in building tools and providing services as part of its RDA Registry development. The evolution of the current RDA Registry and the Open Metadata Registry (OMR), on which the RDA Registry is built, are described, including the rationale for directions, decisions, and ongoing development.

TL;DR: The BDA Museum Collection is created as a BDArt subcommunity using an XML export procedure that is expected to be helpful in future developments of other museum collections in the Thematic Repository at U.Porto.
Abstract: The Biblioteca Digital de Arte (BDArt) Digital Library hosted by the Thematic Repository at the University of Porto (Repositorio Tematico da U.Porto) aggregates documents from the library and the archive collections belonging to the Fine Arts School of the University of Porto (Faculdade de Belas Artes da U.Porto). This school has a museum collection containing a significant set of world-class objects managed with distinct processes and tools from those currently used in libraries and archives elsewhere. Interoperability between the collections of the archive, the library, and the museum is necessary because many works allocated to different collections are closely related and can only be seen as a whole by cross-collection search functionalities. The goal of this work, the first of its kind to be developed at the University of Porto (U. Porto), is to integrate the museum collection with archives and library collections in the repository and to use an open-source technology (DSpace). Our experiment involve...

TL;DR: This planned service will complement shared authority services such as the Virtual International Authority File and the Social Networks and Archival Context project, providing a means for institutions managing authority data about people, organizations, and families not typically found in authority files centered around bibliographic metadata to share that data with other institutions.
Abstract: Efforts are underway to publish archival authority information in linked, open, machine-readable data standards. However, these efforts have not yet scaled down to smaller institutions or to the long tail of authority records maintained on an institution-by-institution basis (often non–standards-based) about entities of local (rather than national or international) significance. This article documents the initial steps toward developing a shared authority tool for a collective of cultural institutions with shared collecting affinities, whether those affinities are geographic, thematic, or otherwise. This planned service will complement shared authority services such as the Virtual International Authority File (VIAF) and the Social Networks and Archival Context (SNAC) project, providing a means for institutions managing authority data about people, organizations, and families not typically found in authority files centered around bibliographic metadata to share that data with other institutions.
TL;DR: The University of Denver cataloged and digitized the whole of an archival collection in two years by taking advantage of patterns inherent in archival arrangement to batch-create metadata using Archival collection management software.
Abstract: Academic librarians and archivists have long partnered on the development and implementation of cataloging best practices for archival materials. Much of this shared history involves cataloging in traditional integrated library systems, using metadata, descriptive standards, and software originating in bibliographic cataloging to create records in artisanal detail. The University of Denver cataloged and digitized the whole of an archival collection in two years by taking advantage of patterns inherent in archival arrangement to batch-create metadata using archival collection management software. Using this approach, the University of Denver scaled up the production of records, while keeping costs down and maintaining quality, and developed a set of best practices that has extended to other shared cataloging and digitization projects.
TL;DR: The Artists’ Books Thesaurus provides a case study for the inclusion of visual content in library thesauri using skos:example.com and demonstrates a model for back-end management ofVisual content and front-end browsing and discovery solutions.
Abstract: The Artists’ Books Thesaurus provides a case study for the inclusion of visual content in library thesauri using skos:example. It demonstrates a model for back-end management of visual content and front-end browsing and discovery solutions (including social media). External image links upgrade the thesaurus to five-star, Linked Open Data, and integrate the thesaurus with the Semantic Web. This work shows that inclusion of visual content in library thesauri is achievable using free, open-source Web tools and a simple curatorial workflow.
TL;DR: An application profile of the metadata schema MODS (Metadata Object Description Schema) is described to describe complex digital musical resources at the University of York to create “bilevel” records, in which component parts of a recording can be described in the same amount of detail as the whole.
Abstract: We describe the development of an application profile of the metadata schema MODS (Metadata Object Description Schema) to describe complex digital musical resources at the University of York (specifically, the Music Preserved archive and John R. T. Davies jazz collection). The profile makes use of the MODS element to create “bilevel” records, in which component parts of a recording can be described in the same amount of detail as the whole. This is useful where recordings contain several musical works and other nonmusical elements, such as applause or announcements. Such recordings may be regarded as historical, as well as musical, artefacts, and we discuss the implication of this for metadata. We considered the abstract model Functional Requirements for Bibliographic Records (FRBR) as an alternative approach to MODS but concluded that our conception of musical recordings as historical artefacts challenged the primacy of the “Work” concept in FRBR. We concluded that MODS was a suitable schem...
TL;DR: An experiment is described that exploits these non-OAI Web-based sources for extracting metadata, which can be used in enhancing an OAI-based service provider.
Abstract: Discovery tools for scholarly information have largely depended upon free-text search engines until the arrival of Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH)–based services. OAI-based service providers are meant to provide a metadata-based unified search for widely distributed scholarly resources. While the proliferation of OAI-PMH–compliant repositories is a welcome development, its overall adoption in these primary resources has been slow. Compared to the vast number of active peer-reviewed journals available today, very few of them expose their metadata through the OAI interface. The publishers have been promoting their publications through various web-based media including email alerts, RSS feeds, and an online table of contents. This paper describes an experiment that exploits these non-OAI Web-based sources for extracting metadata, which can be used in enhancing an OAI-based service provider.
