Virtual Observatories

The growth in accessible data within the Virtual Observatory (VO) initiative has led to new challenges in scientific analysis, data management, computational throughput, and dissemination of results from massive archives. In order to choreograph scientific analysis and optimise the usage of data storage and processing resources across these archives, workflow methods are increasingly being employed.

We are developing workflow systems to allow VO exploratory tools to be built with the WebCom-G workflow engine ( www.webcom-g.org) and the Open Run-Time Environment ( www.open-rte.org) working in conjunction with other process management systems.

Applications of these software systems to the analysis of existing large data sets from high time resolution astrophysics within the VO context will allow faster and more complete knowledge extraction from these studies. In turn this will allow a closer marriage of experimental and instrument design for future.
