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 visualisation 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.
VRML is playing a more and more important part in the context of industrial Intranet applications for the 3D visualization of product and production data. New industrial areas of application are opening up and create new requirements for VRML authoring tools. In this paper we want to show the use of VRML in the context of industrial applications based on several examples. Furthermore we will deduce additional authoring requirements that must be met by VRML authoring tools in order to suit the discussed industrial application examples and suggest a solution concept. W e show the realization of this approach on the basis of a new set of VRML authoring tools and make a point of how the special authoring concepts described can be used to solve the generat authoring problem.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
