In this paper we introduce a new architecture, called Open Collaborative Grid Services Architecture (OCGSA) that serves as the building block for designing collaborative services within Grids. The framework is based on the Open Grid Services Architecture (OGSA) that combines aspects of Grids with Web services. Using OGSA enables users to access advanced Grid features such as lifetime management, notification, and security that are otherwise not available in Web services. Our framework provides high-level Grid services that can be integrated within future collaborative applications, hence making them automatically Grid aware. Besides the definition of such useful advanced collaborative services, we use this architecture to validate the approach taken in OGSA and verify whether necessary collaborative services can be implemented with the help of OGSA. Use of these services will also enable the creation of peer-to-peer collaborative infrastructures.
