摘要：The paper brings a review of the linked data concept as a semantic upgrade of the existing World Wide Web. It also analyzes the possibility of integrating library catalog and services into the intelligently linked network – semantic web. The first part of the paper presents some basic principles of the semantic web in general. Then we discuss the main elements of the linked data (URI - Uniform Resource Identifiers and RDF - Resource Description Framework), its principal concepts, publishing procedure, licensing and some security issues. The next section explains the main advantage of linked data searching in comparison with the conventional web search. Furthermore, we discuss the application of linked data on library catalogue records. MARC properties are analyzed in a network environment as well as the difference between catalogue with linked data and traditional library catalogue. The analysis has shown that MARC record is only readable, while the same record in RDF/XML format integrated into linked data is also understandable in the semantic sense. The conclusion is that the linked data technology presents a great opportunity for further development of library catalogues and library services, but also a was to improve efficiency in the intelligently linked global network.
