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.

- Day2: Research and Education- Student Portals,- Learning (SAKAI)- Collaboration (Nature, SURFnet, TeraGrid)
Slides and videos:http://docs.opensocial.org/pages/viewpage.action?pageId=720955
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
Much more: join mailinglist [email protected]
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 ?!

Groups in COIN
- Groups are managed centrally
- Any acceptable user can become a collabmin
- Groups provide context for applications
- Groups feature (only) 3 roles (admin, collabmin,
member)
- Group + VO Registry VO IdP
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
