Citation Linking in Federated Digital Libraries

Today, bibliographical information is kept in a variety of data sources world wide, some of them publically available, and some of them also offering information about citations made in publications. But as most of those sources cover only certain areas of publications it is currently not possible to follow citation links when information about the referenced publication is not stored locally. This is known as the citation linking problem. In this paper we present an approach to integrating bibliographical information including citation information from various sources providing a platform for the solution of the citation linking problem. The approach is based on a loosely coupled federation using the FRAQL language and its conflict resolution mechanisms. Furthermore, we describe an adapter allowing a seamless integration of various sources in an heterogeneous and highly distributed environment.
