Building a Heterogeneous Network of Digital Libraries on the Semantic Web

Ever since computer networks have become popular libraries tend to join into federations. Each federated digital library, apart from delivering discovery and navigation features within their own database allows users to search among other digital library systems. However the variety of users introduces various types of libraries and eventually types of federations of libraries. We present the current state of communication between digital libraries. We also present how Semantic Web technologies can help to overcome the problems with creating heterogeneous networks of digital libraries. We finally exemplify possible solutions with existing tools.
