Primary Objectives
Consolidate the existing middleware distribution simplifying services and components to make them more sustainable (including use of off-the-shelf and commercial components whenever possible)
Evolve the middleware services/functionality following the requirements of infrastructures and users, mainly focusing on operational, standardization and interoperability aspects
Reactively and proactively maintain the middleware distribution to keep it in line with the growing infrastructure usage

EMI Position
• Interoperability and standardization play a fundamental role in the EMI strategy– Interoperability is the native capability of systems to exchange
information, resources and data using agreed interfaces• The only long-term solution• Complexity is independent from the number of systems• Requires coordination and planning• Sustainable

Types of Interoperability
• EMI works on three interoperability scenarios– Interoperability between different implementations of the
same services or functionality– Interoperability among HTC and HPC resources/technologies– Interoperability with emerging technologies
• Collaboration with other DCIs: StratusLab, VENUS-C, EDGI, IGE

Community Vs. De Facto Standards
• In the EMI plan all services must:– Implement the ‘best’ relevant standards– Implement them in the same way
• ‘Best’ means:– A ‘community’ standard, if it is useful, usable or can be
realistically improved– A ‘de facto’ standard, if no community standard exists or what
exists is clearly not usable
• The adoption of good de facto standards is not an alternative to widely agreed community standards, but rather a first practical step in the standardization roadmap to provide feedback and create awareness

Standardization Activities (1)
• Actively take part in the European standardization roadmap coordinated by the European Commission and SIENA
• Actively take part in SDOs – Consumer:
• Feedback, recommendations, lessons learned from the adoption of community standards
– Contributor: • Skills and expertise • Feedback and recommendations from the adoption of ‘good de
facto standards’ – Early adopter:
• Feedback on the adoption of early standard versions

Standardization Activities (2)
• Open Grid Forum (OGF)– Production Grid Infrastructure (PGI) Working Group – Grid Interoperation Now (GIN) Community Group – Usage Record (UR) Working Group
• Organization for the Advancement of Structured Information Standards (OASIS)– Security Assertion Markup Language (SAML) – Extensible Access Control Markup Language (XACML)
