Context
•Internet– 1.5 billion fixed connections– Estimated 4 billion mobile connections
•Digital Storage– Estimated 280 billion Gigabytes
•Users :– Asia 550 million 14% penetration– Europe 350 million 50% penetration– USA 250 million 70% penetration
•Expect technology to grow ~ 1 order of magnitude each 4 years
– and accelerating

So…
•This is the ‘internet of things’ or ‘future internet’•We need to :
– Manage the huge numbers, sizes– Integrate the different kinds of systems– Into one environment leading to human decision-making
• whether managing a business, shopping, media choice, social interaction
•But there is a problem…in last 20 years– Data storage density increased ~10**18– Processor power increased ~10**15– BUT broadband capacity increased ~10**4
IN FACT WE HAVE TO MAKE ICT AUTONOMICAND TO DO THIS REQUIRES METADATA

...and
•The European research infrastructures on (and off) the ESFRI roadmap will be major contributors to and requirers of the e-infrastructure.
•RIs are expensive and so we should optimse (a) their use (b) use of the outputs (data, publications, patents, products etc)
•This requires curation/preservation and in turn this requires metadata
•There is a danger of different RIs / communities doing things differently so precluding interdisciplinary interoperation

Why APA
Mission and GoalsThe Alliance aims to develop a shared vision and framework for a sustainable organisational infrastructure for permanent access to scientific informationMajor stakeholders in European science have therefore joined together to establish an Alliance for Permanent Access to the Records of Science. http://www.alliancepermanentaccess.eu/Annual Conference 23rd November 2010

Metadata
•Discovery• description
•Matching for use• Functional and non-functional
•Access and access restrictions• Security, privacy, trust, cost
•Integrity, accuracy, quality• Schema
•Provenance• Temporal
•Curation / Preservation
•Functions and aspects of metadata•For services or datasets•All inter-related

Conclusion
There is a way forward for the e-infrastructure and the curation/preservation of research data / software / servicesIt is based on bringing together all the relevant strands of R&D
