Daffodil: An integrated desktop for supporting high-level search activities in federated digital libraries

Abstract

Daffodil is a digital library system targeting at strategic support during the information search process. For the user, mainly high-level search functions, so-called stratagems, implement this strategic support, which provide functionality beyond today’s digital libraries. Through the tight integration of stratagems and with the federation of heterogeneous digital libraries, Daffodil reaches a high synergy effect for information and services. These effects provide high-quality metadata for the searcher through an intuitively controllable user interface. The visualization of stratagems is based on a strictly object-oriented tool-based model. This paper presents the graphical user interface with a particular view on the integration of stratagems to enable strategic support.
