The simplest part of sound preservation involves technology and its application. The real complexities lie in a mix of social legal, and financial issues. The social issues include how archivists, curators, librarians, historians, or anyone with limited engineering, computing, and other technical training can evaluate competing claims and risks. The legal issues include copyright and the risks that an institution may choose to take about what constitutes fair use and preservation copying. The financial issues include how much of what quality of preservation an institution can afford, and for how many of the items in its collection.

The purpose of this chapter is to introduce the basic concepts and principles of linked data, discuss benefits that linked data provides in library environments, and present a short history of the development of library linked data.

The chapter is based on the literature review dealing with linked data, especially focusing on the library field.

In the library field, linked data is especially useful for expanding bibliographic data and authority data. Although diverse structured data is being produced by the library field, the lack of compatibility with the data from other fields currently limits the wider expansion and sharing of linked data.

The value of this chapter can be found in the potential use of linked data in the library field for improving bibliographic and authority data. Especially, this chapter will be useful for library professionals who have interests in the linked data regarding its applications in a library setting.

The library metadata of the twenty-first century is moving toward a linked data model. BIBFRAME, which stands for Bibliographic Framework Initiative, was launched in 2011 with the goal to make bibliographic descriptions sharable and interoperable on the web. Since its inception, BIBFRAME development has made remarkable progress. The focus of BIBFRAME discussions has now shifted from experimentation to implementation. The library community is collaborating with all stakeholders to build the infrastructure for BIBFRAME production in order to provide the environment where BIBFRAME data can be easily created, reused, and shared. This chapter addresses library community's BIBFRAME endeavors, with the focus on Library of Congress, Program for Cooperative Program, Linked Data for Production Phase 2, and OCLC. This chapter discusses BIBFRAME's major differences from the MARC standard with the hope of helping metadata practitioners get a general understanding of the future metadata activity. While the BIBFRAME landscape is beginning to take shape and its practical implications are beginning to develop, it is anticipated that MARC records will continue to be circulated for the foreseeable future. Upcoming multistandard metadata environments will bring new challenges to metadata practitioners, and this chapter addresses the required knowledge and skills for this transitional and multistandard metadata landscape. Finally, this chapter explores BIBFRAME's remaining challenges to realize the BIBFRAME production environment and asserts that BIBFRAME's ultimate goal is to deliver a value-added next-web search experience to our users.

This chapter aims to help librarians understand the underlying rationale for Resource Description and Access (RDA) and recognize the great potential of the Semantic Web for libraries.

It explains the linked data model and Semantic Web technologies in basic, informative terms, and describes how the Semantic Web is constructed. Semantic Web standards and technologies are discussed in detail, including URI, RDF, and ontologies. The study also traces the development of RDA and some of the major library Semantic Web projects. The authors explore how RDA shapes bibliographical data and prepares it for linked data in the Semantic Web. In addition, this study examines what libraries in the United States and the rest of the world have achieved in implementing RDA since its release.

RDA is the correct approach libraries should take.

This is the first and only chapter that covers the development of RDA in other countries as well as in the United States. It is highly informative for anyone who wishes to understand the RDA and Semantic Web and their relevance to libraries in a short period of time.
