The Collaboration game

Modern universities are developing towards loose

conglomerates of (inter)discipline expertise

→ Collaboration is therefor core business

Collaboration involves people in multiple institutions

in multiple countries

Collaboration is about using shared resources

People + resources = Virtual Organization

A distributed landscape

Modern science combines eScience resources from

multiple sources with generic collaboration

- The core resources are within the R&E domain

- Some activities already moving off campus

(MyExperiment, Mendeley)

Collaboration is already in 'the cloud'

Twitter, Facebook, Linkedin, Wikis, Blogs→

Domestication

• Domestication can be described as the process of externalizing authentication, authorization and group management from services

• Domestication fits nicely in the Service Oriented Architecture paradigm where a platform is created for reusable services and service components

• It becomes easier to share (generic) information among services and to replace similar services

• It is only useful in multi-domain collaboration or enterprise environments, hence (delegation of) trust is a point of concern

Domestication (2)

- Domestication Candidates:- Authentication and authorization;- Groups;- Provisioning and deprovisioning;- 'Events' like presence, notifications and

activities;- Monitoring and reporting.

EU OpenSocial Summit -2- Social Networks: facing Facebook- Lot of interest in education and collaboration- 'Enterprise' is catching up, adding OS to tech

stack (and even moving away from traditional Java Portal tech)

- Publishers are moving towards OS

- Integration of OpenSocial Gadgets and W3C widgets spec a must

- There is a need for a standard portal app- A gadget registry is needed

OpenSocial 2.0- Integration of OpenSocial Gadgets and W3C

widgets spec

- Integration/Alignment of OpenSocial and CMIS

- OpenSocial Spaces (Gadgets + Groups + People): sharable between containers

W3C Federated Social Web

Many initiatives to create 'federated' Social Networks

This initiative tries to bundle these initiatives and come up with an open standard for (realtime) exchange of Social Data between Social Network Platforms

Looks like XMPP / GoogleWave ?!

Service Registry - Janus

Why OpenSocial ?

- Open 'Social Data' API for exchanging information on people, groups, activities, etc (Javascript and REST API)

- But also,- general purpose web integration technology

('Gadgets')- Open standard browser based components- vendor neutral & platform independent

PortabilityWrite once, deploy anywhere

- Large user community -> wide spread adoption

How will (end) usersexperience COIN
