EU Innobarometer study (2006)
• Main motivations to join cluster:• Hiring of skilled people (64%)• Exchanging information on market (62%)• Stimulating the entrepreneurship spirit (61%)• Developing partnerships on specific business projects
(59%)• Exchanging best practices (57%)• Exchanging information on technology (55%)• Facilitating access to finance (47%)• Facilitating sharing of infrastructures (e.g. buildings,
research labs, training• facilities) (46%)• Access to research infrastructures (labs, universities,
etc) (43%)• Developing partnerships to compete in the European
market (42%)• Shortening time to enter market (41%)• Facilitating access to land (32%)
“By 2009, 60% of new collaboration related IT projects will seamlessly incorporate supplier, partner and customer personnel – up from fewer than 10% in 2004” (Gartner 2005)

“No longer is meticulous repetition in machine bureaucracies the key to generating value. Instead companies that flourish are those that show they can exploit the capital that is associated with a talented independent workforce. The value of this ability is seldom reflected in market capitalisation of companies even though it has a great impact on revenues and profits.”

• A distributed system, even if the goal is transparency, has several co-existing domains of interoperability
• A domain is a set of objects sharing a common characteristic or abiding by common rules.

Next…?
• Investigate richer published subject services• Discovery services (pragmatic interop)
• How used?• By who?• Update services (dynamic interop)• Metamodel mappings (conceptual interop)
• ”Snap to Grid” widgets
• Good example cases to copy• Businesses/eGov/communities to grab the opportunities!
