In a data-driven Science Collaborative Framework, access authorization is a vital component to facilitate the management of the collective data and computing resources shared by researchers from geographically distributed locations. But traditional virtual organization based access control frameworks are not suitable for self-organizing, ad-hoc and opportunistic scientific collaborations, in which...
In data-driven science projects, researchers distributed in different institutions often wish to easily team up for data and computing resource sharing to address challenging scientific problems. Typical VO based authorization schemes is not suitable for such a user organized scientific collaboration. Using the emerging OAuthprotocol, we introduce a novel group authorization scheme to support ad-hoc...
A significant obstacle to building usable, web-based interfaces for computational science in a Grid environment is how to deploy scientific applications on computational resources and expose these applications as web services. To streamline the development of these interfaces, we propose a new application framework that can deliver user-defined scientific workflows as both web services and OpenSocial...
To enable the Life Science community to fully use TeraGrid resources for computing and data management, we developed an integrated cyber computational environment named the Open Life Science Gateway. Based on a service-oriented framework, the gateway aggregates a group of bioinformatics applications and data collections into a Web portal. Furthermore, this gateway provides a platform for life science...
