Who are we?
Valencia, 12 and 13 April 2010 NESSI Projects Summit
Open Alliance on Service Front-Ends
Valencia, 12 and 13 April 2010 NESSI Projects Summit
Our Vision
End-user EmpowermentLet users use the Internet of Services the way they want, by picking and assembling web building blocks (e.g. gadgets) available on the Internet and creating their own applications (Mashups)
Valencia, 12 and 13 April 2010 NESSI Projects Summit
Our Vision
Sharing and exchanging of knowledgeUsers know what they need, they are the ones that drive innovation. Allow them to create Gadgets and Mashups and share their knowledge in a highly social environment
Valencia, 12 and 13 April 2010 NESSI Projects Summit
Our Vision
Seamless adaptation to context at any timeUsers change roles and situations, front-ends and applications should follow automatically.
Valencia, 12 and 13 April 2010 NESSI Projects Summit
Our Vision

Future Research Topics
Valencia, 12 and 13 April 2010 NESSI Projects Summit
Mashup as a Service•Put together Mashup+XaaS technologies and concepts.•Go beyond SaaS and PaaS. Allow end users to create their own applications in the cloud just by using existing building blocks •Marketplace capabilities that will allow the creation of rich ecosystem of SFE components for cloud applications on top of a Cloud stack (IaaS + Paas + MaaS+ SaaS)

Future Research Topics
Valencia, 12 and 13 April 2010 NESSI Projects Summit
New Web Runtimes for Cloud Environments•New breed of Cloud Front-End that combine Mashups, Web Desktops and Thin OS runtimes properties•¿Full support of Web Standards and technologies required?•¿Web Browser or Web OS-based?
Future Research Topics
Valencia, 12 and 13 April 2010 NESSI Projects Summit
• Automatic Mashups – Users may create gadgets and application mashups by “clipping”
and “dragging” portions of legacy or new semantically enriched web apps.
– Alternative to dev tools like FAST that could help populate Mashup platforms and drive their mainstream adoption.
• Community-driven Collaborative Front-Ends– Leverage knowledge, relations and patterns of use inside static
communities and mashup environments in order to create opportunistic (a.k.a. situational) communities of users/machines/services that are created dynamically in response to a particular problem that one (or more) user has (consumer) and others can help (provider)
– Real-time collaboration through front-end dynamic mashups.
