Why Services?
Service is something used but not ownedLower the risks for customers and improve value and reliabilityIncrease process flexibility for businesses as well as public administrationsRecognise complex world environments, and co-operate on standards, so the end-user value can be created for a huge number of people
NESSI is about transforming the EU economy through Service Oriented business models

NESSI ETP
European Technology Platform:Networked European Software and Services Initiative
NESSI aims to provide a unified view for European research in Services Architectures and Software Infrastructures
Today, NESSI partners represent 1.7 Million strong workforce and 490 B in revenues
In US, SRII launched in March 2007 (www.thesrii.org)

What is NEXOF?
The NESSI Open Framework (NEXOF) is a coherent and consistent open service framework, ranging from the infrastructure up to the interfaces with the end users, leveraging research in the area of service-based systems to consolidate and trigger innovation in service-oriented economies

NEXOF main concepts
NESSI Open Service FrameworkOpen Reference Model (ORM)Open Reference Architecture (ORA)Open Reference Implementation (ORI)Conformance Test Suite

NEXOF-RA
NEXOF-RA is a step in the process of building and creating the conditions for the adoption of the whole of Open Service FrameworkScope is the Open Reference Model and Open Reference ArchitectureThe aim is that the RA will be built through consensus within the NESSI Community, validated by the NSPs and widely adopted to support the European Service EconomyProof of concept implementations

Conclusions
NEXOF-RA aims to standardise the way services are built, offered and consumed.The Reference Architecture should be defined in order to allow any business domain, size and technologiesImplementing a Reference Architecture is not a single shotImplementing a Reference Architecture requires a large community with contributions from many sources.

1st set of Investigation Teams kickoff:20-21 October 2008strong interest, large number of committed contributors 2nd call coming soon (December 2008)
