  1. On Exploiting DIVERSITYe-professionals scenarioPaola InverardiDipartimento di InformaticaUniversità dell’AquilaItaly

  2. Supporting/Middleware (Meta-) Issues • Support virtual community set up on-the-fly for a transient common goal (“transient conscious/unconscious collaboration” ). Assuming DIVERSITY. • Creation : discovery of peers, communication set up • Organization: rules the community relies on • Coordination: how independent activities synchronize to reach the common goal *** Multiple roles at the same time (handle dynamically and consistently the co-existence of multiple environments).

  3. Research Challenges • Reference architecture : adaptability for lightweight deployment, content/goal driven • Interaction among peers : utility-like computing capacity and connectivity • Semantic modelling : ontologies for collaboration, knowledge building management, negotiation knowledge • Contextualization and content of mobile and collaborative environments • Trust, security and privacy management

  4. Reference Architecture & Middleware – 1 – Users Context Mgmt Reference Architecture -- Abstraction to support remote services and applications Middleware for Service Facilitator Support Layer Network Abstraction Sublayer Network Layer

  5. Reference Architecture – 2 – Middleware for Service Facilitator Support Discovery (peers, resources, services) Negotiation capabilities Trust & Security Knowledge management Communication Interaction patterns …

  6. Reference Architecture – 3 – • Which interaction paradigm? • Peer-to-peer • Content-based, publish-subscribe • Service Oriented Architecture • Client-server • Grid • … The Middleware should allow easy customization of the reference architecture for specific application domains

  7. E-professional scenario Participants • Olavi Luotonen (moderator) EC • Wolfgang Appelt FIT Fraunhofer • Stefano Beco Datamat • Antonio Gomez Universidad Murcia • Paola Inverardi University of L’Aquila • Klaus Satzke Alcatel RTD
