Who are we?
Valencia, 12 and 13 April 2010
NESSI Projects Summit
Open Alliance on Service Front-Ends
A common vision on the technologies and architecture associated
to Service Front Ends in the future Internet of Services
Open specifications and open source reference implementations
of components of the envisioned architecture
Valencia, 12 and 13 April 2010
NESSI Projects Summit
Our Vision
End-user Empowerment
Let 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 knowledge
Users 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 time
Users change roles and situations, front-ends
and applications should follow automatically.

Status and Achievements
FAST
• User-oriented gadget
development based on a novel
screen-flow paradigm
• Drag-and-drop screens to create
gadgets
• Drag-and-drop services and UI
elements to create screens
• Semantic search of components
• Post/pre conditions automatically
determine flow
• The result can be standalone or
exported to any Mashup platform
• Fully functional prototype already
available

Future Research Topics
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
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?
Valencia, 12 and 13 April 2010
NESSI Projects Summit
Future Research Topics
• 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.
