Hyperdatabases: Infrastructure for the Information Space [chapter]

Hans-Jörg Schek
2002 Lecture Notes in Computer Science  
Moreover, we present the ETHWorid project and its sub-projects in which we apply hyperdatabase concepts for managing and organizing the information space of a virtual campus.  ...  The amount of stored information is exploding while, at the same time, tools for accessing relevant information are rather under-developed.  ...  In addition, it provides support for processes realizing complex applications within the information space and guaranteeing a consistent view on the overall information space.  ...

Infrastructure for Information Spaces [chapter]

Hans-Jörg Schek, Heiko Schuldt, Christoph Schuler, Roger Weber
2002 Lecture Notes in Computer Science  
So, the infrastructure for information spaces must provide convenient tools for accessing information, for developing applications for analyzing, mining, classifying, and processing information, and for  ...  In this paper we will elaborate some of the aspects related to process-based coordination within the information space and report on research from our hyperdatabase research framework and from experiences  ...  Conclusions In this paper, we have discussed the various requirements for an infrastructure aiming at maintaining and managing community information spaces.  ...

Scalable peer-to-peer process management - the OSIRIS approach

C. Schuler, R. Weber, H. Schuldt, H.-J. Schek
2004 Proceedings. IEEE International Conference on Web Services, 2004.  
The resources of this coordinator limit the number of concurrent process executions, especially since the coordinator has to persistently store each state change for recovery purposes.  ...  By distributing the execution and navigation costs, we can achieve a higher degree of scalability allowing for a much larger throughput of processes compared to centralized solutions.  ...  Acknowledgment: We want to thank Frank Leymann for supporting the work on OSIRIS and IBM for providing us with equipment enabling further studies on the benefits of the peer-to-peer approach of OSIRIS.  ...

Next-generation applications in healthcare digital libraries using semantic service composition and coordination

Thorsten Möller, Heiko Schuldt, Andreas Gerber, Matthias Klusch
2006 Health Informatics Journal  
A dedicated component plans compound semantic services on demand for a particular application. In failure, the planner is reinvoked to define contingency strategies.  ...  Finally, matchmaking is effected at runtime by choosing the appropriate service provider. These combined technologies will provide key support for highly flexible next-generation DL applications.  ...  Based on the hyperdatabase vision [25] , ideas from process management, peer-to-peer networks, database technology, and Grid [26] infrastructures have been combined.  ...
