Vision 1 Web 2.0

• An Internet for the users to collaborate, share,
  
• Without background experts or support
• W 2.0 by Tim OReilly http//www.oreillynet.com/l
  pt/a/6228
• gt Deliver Services, not software

Vision 2 Collaboration_at_work EU

• A User Centric Vision of Collaborative Work
  Environments
• Users of NG CWEs shall have
• seemless access anywhere, anytime to
• persons, knowledge virtualised resources,
• in a trusted environment where
• groups can be created as needed
• across enterprises boundaries
• Challenges
• Reference Architecture
• Service Oriented, P2P, PlugPlay, IPv6,
  middleware,
• Semantic Data Compatibility Ontologies for
  collaboration
• Support for privacy, trust Dynamic virtual
  organisations
• Seemless device independent access anytime,
  anywhere

Vision 3 Isabel Service Concept

• Fully distributed service for interconnecting
  Audiences
• in multi-point configurations over broadband
  networks
• Implementation decisions (the flexible floor)
• Use TV production techniques
• gt View only or highlight active sites
• Extend rules of presential activities over the
  network
• gt Support standard rules and roles of activities
• Services include a set of interaction modes
• gt Controlled following presential rules
• Session or meeting chair, speaker, participant,
• Evolution several services using a different
  floor control

Vision 4 Evolution of Isabel

• Evolution towards C_at_W and Web 2.0 paradigm (I)
• Offer a Service (not an application)
• Installation-less deployment configuration
• Offered as a service from a portal
• Desktop configuration trivial, audience more
  difficult
• Interconnect room and desktop conferencing
• Both needs are important
• Seamless and device independent access
• Mobile and from any terminal

Vision 4 Evolution of Isabel

• Evolution towards C_at_W and Web 2.0 paradigm (II)
• Interworking Reference Architecture
• Present standards not enough.
• IETF is working on it (XCON, SIPPING, ..)
• Architecture should be Service Oriented
• Allow integration into remaining CWE functions
  and services
• Traversing over Firewalls, NATs,
• But supporting also IPv6 and end to end
  communication
• .

CWEs in Profesional Learning

• Most requirements similar to other CWEs
• Easy of use and deployment, PlugPlay, etc.
• Some requirements are service specific
  (different)
• Support rules and roles of standard training
• The Isabel Tele-class service is taylored to
  lecturing
• Other services are conceivable
• Similar to LMS support to educational processes
• Classroom interconnection will play an important
• Linked to access from desktops or remote sites
• With seamless access anywhere anytime
• From any device
• Knowledge rich environment
• providing seamless access to required knowledge

Service Examples

• Telemeeting
• Interactive meetings with distributed floor
  control
• Main goal easy and natural use
• Teleclass
• Distributed classrooms with semi-centralized
  control
• Control by lecturer or support staff
• Teleconference
• Distributed auditorium with centralized control
• Script driven for effective program realisation

PROLEARN What should we do

• Make more intensive use of CWEs
• Many presential activities could be made
  distributed
• Examples
• Isabel could be used if deployed in all sites
• Workshops and meetings over the network
• Use webcasting to disseminate to project and
  third parties
• With backward interaction channels chat, email,
  
• Work on interworking solutions
• The general solution is a long term goal
• Standards and state of the art have to evolve
• Should PROLEARN contribute to standards?
• PROLEARN should at least work on particular
  interworkings

Communicating Collaborating

• The Internet
• means for Communicating and Collaborating
• The main waves of use of the Internet have been
• First driver email exchange (the 80s)
• Group support FTP server and email list
• Second driver Web (the 90s)
• Electronic image publishing, access to remote
  services
• Third driver P2P (late 90s)
• Communities for exchange of music, movies, files,
  etc.
• Fourth driver blogs (the 00s)
• Universe of syndicated diaries
