Open social based collaborative science gateways

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 team formation and user controlled resource sharing. Integrating this group authorization scheme, we define an Open Social based scientific collaboration framework and develop a science gateway prototype named as Open Life Science Gateway (OLSGW) to verify and refine the framework. Our experience with development of the OLSGW shows that OAuth 2.0 based group authorization scheme is avery promising approach to resource sharing in Cloud environments, and the Open Social based framework can facilitate science gateway developers to create domain-specific collaborative applications in a very flexible way.
