The Pervasive Collaborative Computing Environment (PCCE)
Many of the tools currently available for collaboration focus on heavy-weight applications
such as videoconferencing tools. While these are important for providing telepresence
when there is a high level of interaction, our experience building
distributed collaboratories has shown us that there is a
more basic need for collaboration tools that support connecting people so that they feel
as though they are working together on an ad hoc or continuous basis. Tools that support
the day-to-day connectivity and underlying needs of a group of collaborators are
important for providing lighter weight, less intrusive, and more flexible ways to stay
in touch and work together. Towards this goal we are developing a Pervasive
Collaborative Computing Environment (PCCE) within which participants can rendezvous and
interact with each other. The PCCE aims to:
- Support continuous or ad hoc collaboration
- Target daily tasks and base connectivity
- Be easy to use and install across multiple platforms
- Leverage off of existing components when possible
- Use standards-based components
- Leverage off of Grid services (e.g., security and directory services)
The PCCE is a persistent space that supports continuous and ad hoc collaboration.
It targets daily tasks such as document sharing and provides a base connectivity for
communication.
The XMPP text-based messaging component provides a place to securely find and
interact with other collaborators in a way that is more immediate than email but less
intrusive than the telephone. The BPEL workflow tools allow visual composition and tracking of the workflow of the scientific computations. This workflow capability is integrated with web services and grid components.
The PCCE allows colocated or geographically dispersed
collaborators to:
- Find and contact other participants
- Send instant messages synchronously and asynchronously
- Hold private and group conversations
- Participate in multiple conversations simultaneously
- Archive interactions
- Submit and track current workflow
- Dynamically activate application sharing and videoconference sessions as needed
