Metadata quality: Generating SHACL rules from UML class diagrams
No full textMetadata plays a fundamental role beyond classified data, as data needs to be transformed, integrated, and transmitted. Like data, metadata needs to be harvested, standardized and validated. Metadata management processes require resources. The challenge for organizations is to make the processes more efficient, while maintaining and even increasing confidence in their data. While RDF harvesting has already become an important step implemented at large scale (European Data Portal), there is now a need to introduce a RDF validation mechanism. However such a mechanism will depend upon the definition of RDF standards. When a standard is set, the provision of a validation service is necessary to determine if metadata complies, as for example with the HTML validation service
Wikidata and Scholia for scholarly profiles: the IU Lilly Family School of Philanthropy pilot project
No full textDuring recent years, cultural heritage institutions have become increasingly interested in participating in open knowledge projects. The most commonly known of these projects is Wikipedia, the online encyclopedia. Libraries and archives in particular, are also showing an interest in contributing their data to Wikidata, the newest project of the Wikimedia Foundation. Wikidata, a sister project to Wikipedia, is a free knowledge base where structured linked data is stored. It aims to be the data hub for all Wikimedia projects. The Wiki community has developed numerous tools and web-based applications to facilitate the contribution of content to Wikidata and to display the data in more meaningful ways. One such web-based application is Scholia which was created to provide users with complete scholarly profiles by making live SPARQL queries to Wikidata and displaying the information in an appealing and effective manner. Scholia provides a comprehensive sketch of the author’s scholarship. This presentation will demonstrate our efforts to contribute data related to our faculty members to Wikidata and will provide a demo of Scholia’s functionalities
Linked Data Publishing and Ontology in Korea Libraries
No full textThis posters is to anylze the LOD publishing and reusing the external LODs, and to suggest the future direction for LOD services in Korea. This poster is to analyze the LOD publishing and reusing the external LODs, and to suggest the future direction for LOD service in Korea. For this study, literature reviews and case study are carried on. For case study, KERIS, NLK, and KISTI are selected, which are the major organizations related to the library linked data. They have been publishing the linked open data of bibliographic records and authority data with interlinking the external LOD such as VIAF, LDS, BNB, ISNI, WorldCat, and so on. We analyzed the characteristics of three services – (1) subject domain, (2) volumes of bibliographic, authority, and subject data, (3) bibliographic, name, and subject ontology, (4) local ontology, and (5) interlinking external LOD. As the result for comparing three LOD services in aspect of ontology, FOAF, SKOS, DC, BIBO are common for all, and but MODS, DCTERMS, BIBFRAME, PRISM, and Bibtex are different ontology. Also all services have their own ontology – properties and classes. These local property and class has not consistency and has potential conflict between ontology. In aspect requirements for metadata, interoperability is very important requirement. The reason that locals developed their own ontology is lack of classes and properties for describing data for constructing LOD. Therefore LC BIBFRAME is developed as specific ontology for library sector
Author Identifier Analysis: Name Authority Control in Two Institutional Repositories
No full textThe aim of this poster is to analyze name authority control in two institutional repositories to determine the extent to which faculty researchers are represented in researcher identifier databases. A purposive sample of 50 faculty authors from Florida Southern College (FSC) and Ryerson University (RU) were compared against five different authority databases: Library of Congress Name Authority File (LCNAF), Scopus, Open Researcher and Contributor ID (ORCID), Virtual International Authority File (VIAF), and International Standard Name Identifier (ISNI). We first analyzed the results locally, then compared them between the two institutions. The findings show that while LCNAF and Scopus results are comparable between the two institutions, the difference in the ORCID, VIAF, and ISNI are considerable. Additionally, the results show that the majority of authors at each institution are represented in two or three external databases. This has implications for enhancing local authority data by linking to external identifier authority data to augment institutional repository metadata
Designing a Multilingual Knowledge Graph as a Service for Cultural Heritage – Some Challenges and Solutions
No full textEuropeana gives access to data from Galleries, Libraries, Archives and Museums across Europe. Semantic and multilingual diversity as well as the variable quality of our metadata makes it difficult to create a digital library offering end-user services such as multilingual search. To palliate this, we build an “Entity Collection”, a knowledge graph that holds data about entities (places, people, concepts and organizations) bringing context to the cultural heritage objects. The diversity and heterogeneity of our metadata has encouraged us to re-use and combine third-party data instead of relying only on those contributed by our own providers. This raises however a number of design issues. This paper lists the most important of these and describes our choices for tackling them using Linked Data and Semantic Web approaches
Categorization Ethics: Questions about Lying, Moral Truth, Privacy and Big Data
No full textCategorization is a common human behavior and it has many social implications. While categorization helps us make sense of the world around us, it also affects how we perceive the world, what we like and dislike, who we feel comfortable with and who we fear. Categorization is affected by our family, culture and education. But we can take responsibility for our own perceptions, misperceptions can be pointed out and sometimes changed. But what about categorization imposed outside of us that affects us. Should that be allowed? How is that determined? How can it be changed? These are difficult issues. For information aggregators and information analyzers, the guidelines for appropriate behavior are not always clear, nor is the responsibility for outcomes as a result of errors, bias and worse … When errors and bias are commonly held, this can be reflected in the information ecology. The tipping point need not be a majority, truth or based on ethics. It’s easy enough to identify cases of mis-categorization, but when do you do something about it? What can you do about it
Building a Framework to Encourage the use of Metadata in Modern Web-Design
No full textWhen Tim Berners-Lee published the roadmap for the semantic web in 1998, it was a promising glimpse into what could be accomplished with a standardized metadata system, but nearly 20 years later, adoption of the semantic web has been less than stellar. In those years, web technology has changed drastically, and techniques for implementing semantic web compliant sites have become relatively inaccessible. This poster outlines a JavaScript framework called Beltline.js which seeks to encourage the use of metadata by making it easy to integrate into modern web best-practices
Metadata Models for Organizing Digital Archives on the Web: Metadata-Centric Projects at Tsukuba and Lessons Learned
No full textThere exist many digital collections of cultural and historical resources, referred to as digital archives in this paper. Domains of digital archives are expanding from traditional cultural heritage objects to new areas such as popular culture and intangible entities. Though it is known that metadata models and authority records, such as subject vocabularies, are essential in building digital archives, they are not yet well established in these new domains. Another crucial issue is semantic linking among resources within a digital archive and across digital archives. Metadata aggregation is an essential aspect for the resource linking. This paper overviews three metadata-centric on-going research projects by the authors and discusses some lessons learned from them. The subject domains of these research projects are disaster records of the 2011 Great East Japan Earthquake, Japanese popular culture such as Manga, Anime and Games, and cultural heritage resources in South and Southeast Asia. The main goal of this paper is not to report on these projects as completed research, but to discuss issues of metadata models and aggregation which are important in organizing digital archives in the web-based information environment
Modeling and application profiles in the Art and Rare Materials BIBFRAME Ontology Extension
Get PDFSince April 2016, the Art Libraries Society of North America's Cataloging Advisory Committee (CAC) and the RBMS Bibliographic Standards Committee (BSC) have collaborated with the Andrew W. Mellon Foundation funded Linked Data for Production project on the Art and Rare Materials BIBFRAME Ontology Extension (ARM). BIBFRAME leaves some areas underdefined that need to be expanded by specialized communities. More specifically, ARM facilitates the descriptive needs of the art and rare materials communities in areas such as exhibitions, materials, measurements, physical condition and much more. Between April 2016 and February 2018, work focused on modeling. In February 2018, our focus shifted to development of SHACL application profiles for Art resources and a Rare Monographs, which we are using to define forms and display for the cataloging environment in VitroLib, an RDF-based, ontology agnostic cataloging tool being developed as part of the Linked Data for Libraries - Labs project that was discussed at DCMI 2017. Since these application profiles are being implemented in VitroLib, catalogers will be able to test the ARM modeling in a real-world environment, providing feedback to the project for potential future development. This presentation will provide an overview of select ARM modeling components, detail the process of creating and defining SHACL application profiles for ARM, and discuss challenges and opportunities for implementing these profiles in VitroLib. Further, we will discuss our strategy for low-threshold hosting of the ontology and administrative questions regarding long-term maintenance of this BIBFRAME extension
Metadata as Content: Navigating the Intersection of Repositories, Documentation, and Legacy Futures
No full textDocumentary Relations of the Southwest (DRSW) is a dataset of bibliographic metadata derived from over 1500 reels of microfilmed documents that trace the history of the southwest from the 16th century until Mexico's independence in 1821. Originally made available to scholars through a now defunct proprietary repository, DRSW’s future is currently being assessed in the context of other repository solutions. While migrating content is a familiar scenario, this migration highlights key challenges in navigating the intersection of legacy design and possible futures for metadata curation and repository selection. This presentation deals with challenges revolving around three paradigms: metadata as content, system documentation generation, and metadata futures for indexing and integratio
