ital-10432	Ullah, Irfan; Khusro, Shah; Ullah, Asim; Naeem, Muhammad	An Overview of the Current State of Linked and Open Data in Cataloging	2018-12-17	34	.pdf	application/pdf	14765	457	30	Publishing Linked Bibliographic Metadata The University of Illinois Library worked on publishing MARC21 records of 30,000 digitized books as Linked Library Data by adding links, transforming them to LOD-friendly semantics (MODS) and deploying them as RDF with the objective to be used by a wider community.119 To them, using Semantic Web technologies, a book can be linked to related resources and multiple possible CURRENT STATE OF LINKED AND OPEN DATA IN CATALOGING | ULLAH, KHUSRO, ULLAH, AND NAEEM 60 https://doi.org/10.6017/ital.v37i4.10432 contexts, which is an opportunity for libraries to build innovative user-centered services for the dissemination and uses of bibliographic metadata.120 In this regard, the challenge is to utilize the existing book-related bibliographic maximally and descriptive metadata in a manner that parallels with the services (both inside the library and outside) as well as exploit to the fullest the full-text search and Semantic Web technologies, standards, and LOD services.121 While publishing the National Bibliographic Information as free open Linked Data, IFLA identifies several issues including:122 • dealing with the negative financial impact on the revenue generated from traditional metadata services; • the inability to offer consistent services due to the complexity of copyright and licensing frameworks; • the confusion in understanding the difference between “open” and “free” terms; • remodeling library data as Library Linked Data; • the limited persistence and sustainability of Linked Data resources; • the steep learning curve in understanding and applying Linked Data practices to library data; • making choices between sites to link to; and • creating persistent URIs for library data objects. These challenges include:129 • dealing with the bulky or non-available RDF dumps, no authority control within RDF dumps, and data format variations; • identifying terms’ specificity levels during concept matching; • the limited reusability of Library Linked Data due to lack of contextual data; • harmonizing classes and objects at the institution level; • excessive handcrafting due to few off-the-shelf visualization tools; • manual mapping of vocabularies; • matching, aligning, and disambiguating library and Linked Data; • the limited representation of several essential resources as Linked Data due to non- availability of URIs; • the lack of sufficient representative semantics for bibliographic data; • the time-consuming nature of Linked Data to understand its structure for reuse; • the ambiguity of terms across languages; and • the non-stability of endpoints and outdated datasets.	cache/ital-10432.pdf	txt/ital-10432.txt
