Abstract
Problems of developing digital libraries are considered. An analysis of this class of distributed information systems is given. The main effort is focused on the formalization of properties of the stored objects and operations, which makes it possible to construct a formal model of digital libraries. This model can serve as a basis for designing development tools. Systems based on this approach are called integrated information resource systems (IIRS). In particular, the information retrieval system of the Russian Academy of Sciences (IIRS RAS) is based on these principles. The paper is organized as follows. First, the aim of the paper is outlined. Then, the definition of a digital library is given (as it is understood by the authors), basic concepts are discussed, and IIRS is considered as a digital library. The notion of the resource is introduced as the basic object to be processed. Metadata and their role in the system of digital libraries are considered, as well as the role of relationships and data organization. Then, the architecture and functional capabilities of IIRS are considered, and, in particular, a metamodel of the system, data search, and the implementation of data distribution. The current implementation of IIRS RAS is briefly outlined.
