It is produced in a distributed open fashion by museums libraries archives and media organizations as well as individual persons. Managing publication of such richness and variety of content on the Web and at the same time supporting distributed interoperable content creation processes poses challenges where traditional publication approaches need to be re-thought. Application of the principles and technologies of Linked Data and the Semantic Web is a new promising approach to address these problems. This development is leading to the creation of large national and international CH portals such as Europeana to large open data repositories such as the Linked Open Data Cloud and massive publications of linked library data in the U.S. Europe and Asia. Cultural Heritage has become one of the most successful application domains of Linked Data and Semantic Web technologies. This book gives an overview on why when and how Linked (Open) Data and Semantic Web technologies can be employed in practice in publishing CH collections and other content on the Web. The text first motivates and presents a general semantic portal model and publishing framework as a solution approach to distributed semantic content creation based on an ontology infrastructure. On the Semantic Web such an infrastructure includes shared metadata models ontologies and logical reasoning and is supported by shared ontology and other Web services alleviating the use of the new technology and linked data in legacy cataloging systems. The goal of all this is to provide layman users and researchers with new more intelligent and usable Web applications that can be utilized by other Web applications too via well-defined Application Programming Interfaces (API). At the same time it is possible to provide publishing organizations with more cost-efficient solutions for content creation and publication. This book is targeted to computer scientists museum curators librarians archivists and other CH professionals interested in Linked Data and CH applications on the Semantic Web. The text is focused on practice and applications making it suitable to students researchers and practitioners developing Web services and applications of CH as well as to CH managers willing to understand the technical issues and challenges involved in linked data publication.
