OMII-Europe Promoting interoperable Grid systems.
Identifying software components that will interoperate across heterogeneous Grid middleware stacks.
Endorses particular standards which are important for interoperability.
Emphasis on re-engineering to support interoperability rather than reinvention.
Developing a repository of quality-assured components that support interoperability.

OMII-Europe Sixteen partner institutions.
Three in the UK.
The remainder are in Europe, the US and China.
Funded by the EU (at least the European part).
Started in May 2006.
Standards for Interoperable Grids 5
NextGRID Developing an architecture for ‘next generation Grids.’
Enable or support widespread use.
Business and commerce, not just academia.
Address: security, legal and privacy issues.
Support economically viable business models.
Consolidate and standardise the solutions adopted to these problems.
Standards for Interoperable Grids 6
NextGRID
Mixture of industrial and academic institutions.
Twenty two partners.
Seven in the UK.
Coordinated by EPCC and NeSC.
Funded by the EU.
Started in September 2004.
Ends on 31 March 2008.

NextGRID Architecture
NextGRID has developed an architecture capable of supporting the anticipated modes of use.
Details are not germane today.
Worth briefly mentioning the principles behind it.
Discussed in the NextGRID White Paper.
