Resumen
The authors discuss on how to achieve interoperability among the world's scattered digital libraries; and the points to keep in mind when creating the links. The authors present a broad introduction to the issues of interoperability, suggesting factors that may be used in evaluating related solutions and providing an overview of solution classes. Interoperability is gaining in importance as the Internet unites digital libraries of different types run by separate organizations in different countries. At the same time, the increasing power of desktop computers, the increasing bandwidth of networks, and the popularity of mobile code is changing the interoperability landscape. The result is an urgent need to solve the problems hindering true interoperability on national and international scales. They discussed informally because interoperability is a complex topic for which there are no good metrics. The authors focus is on heterogeneous, or federated systems of information resources and services and how they can be made to interoperate.
