Management of large data repositories integrated into the grid poses new challenges for grid research. There already exist several successful data grid projects addressing processing files storing large volumes of scientific data and projects developing services for accessing remote relational and XML databases. However, so far, no effort was devoted to(More)
Database management systems providing powerful data management services have been developed in the recent decades to a great extent. All these systems are based on its own single data model, whereas the demand for managing multiple data sources with different data models is rapidly expanding. Therefore the need for intelligent management systems providing(More)
This work intends to provide a large-scale scientific data management solution based on the concepts of dataspaces for e-Science applications. Our approach is to semantically enrich the existing relationship among primary and derived data items, and to preserve both relationships and data together within a dataspace to be reused by owners and others. To(More)
Earth and life sciences are at the forefront to successfully include computational simulations and modeling. Medical applications are often mentioned as the killer applications for the Grid. The complex methodology and models of Traditional Chinese Medicine offer different approaches to diagnose and treat a persons health condition than typical Western(More)
Case study research excels at bringing us to an understanding of a complex issue or object and can extend experience or add strength to what is already known through previous research. The research work summarized by this paper discusses two different case studies in the field of portals for collaborative research communities, in particular VectorBase and(More)
Chinese and Western medicines have a different understanding and approach to life, health, and illness - joining their complementary work and support them by an advanced information technology could result in an improved health system. The Non-Invasive Blood Glucose Measurement (NIGM) Service is a grid based implementation of a novel non-invasive method for(More)
This paper introduces the advanced breath analysis (ABA) platform, an innovative scientific research platform for the entire breath research domain. Within the ABA project, we are investigating novel data management concepts and semantic web technologies to document breath analysis studies for the long run as well as to enable their full automatic(More)
This work intends to provide a data management solution based on the concepts of dataspaces for the large-scale and long-term management of scientific data. Our approach is to semantically enrich the existing relationship among primary and derived data items, and to preserve both relationships and data together within a dataspace to be reused by owners and(More)
Within the Austrian Grid project phase 2, three different groups, each allocated to a different work package, join their efforts to implement a grid infrastructure for the european research project "Breath Gas Analysis for molecular oriented diseases''. This position paper provides background on the task and the resulting requirements, a presentation on(More)
