The thesis explores the possibilities of interoperability, exchange and reuse of bibliographic data by using current interchange formats. Aim of this work is to explain the importance of data interoperability with focus on bibliographic data. The analysis of data exchange formats is focused on use of XML and JSON as well as formats for writing and sharing bibliographic data in the context of current information services. In addition, the ability to combine these formats with traditional library standard such as representing MARC in MARCXML will be described and analyzed. Today, it is important to generate different forms of structured data for dissemination and management purposes to enable different usage scenarios. Therefore, the thesis presents the advantages of contemporary formats for sharing and writing bibliographic data in different contexts of their use. The thesis will also present some of the problems of conversion of bibliographic data record from MARC to some other contemporary forms such as the problem of complex and nested values or the occurrence of structural punctuation in the values (which often come from ISBD rules). Key terms such as data exchange formats (XML, JSON, CSV), library standards in these formats (MARCXML, MODS), Application Program Interfaces (APIs), standards, data interoperability and other related concepts will also be defined.
