Editor's Notes
Based on a presentation by Peter Burnhill at launch of Discovery – “a UK metadata ecology for UK education and research” in May 2011 JISC consolidation of service
Creating ‘new or novel knowledge products, increasing serendipity, cross-fertilisation of resources a metadata ecology for UK education and research No one size fits all solutions – mixed economies (technical and subject expertise, infrastructures, cultural differences across domains and organisations)
A key concept in the RDTF Vision is aggregation , directly or represented through metadata: to unlock riches held in our organisations, typically digital and online. This recognises the added value in assembly for tactical purpose – to improve ‘discoverability’. The ultimate aim being to improve access for research and educational purpose: for researchers, students and their teachers, - with few barriers for potential take-up beyond that Promiscuous metadata, washing your dirty metadata in public, making sure your metadata is well dressed !!! It’s very easy to publish in the web. Maximising the full potential of that content is another matter entirely.
the audience for any given work, service or aggregation is now machine as well as human Make content easier to use in global informaiton ecosystem, reducing technical and licensing barriers, potential to create new knowledge products or services, foster social innovation, Let your metadata speak for you when you have no one to speak for you, Removeal of duplicate of effort
The process of disintermediation
Technical support provided by EDINA SDSS Expert Group in Identity and Access Management Keep at a strategic level rather than diving into detailed issues and concerns Orientate towards opportunities and feasible steps, however small those might be.

.Aggregation should be regarded as intervention to achieve value added improvement and context as aid to discoverability. Among their recommendations is that “such Aggregations should have supported APIs which are attractive to and convenient for developers”. Interpretation of other recommendations suggest that the Framework should: (a) assist Aggregators (extant and as funded aggregation projects) to demonstrate value to Content Providers were they to progressively follow each of the four Linked Data steps (b) encourage Content Providers to provide a semantic sitemap prior data aggregation, e.g. publication of RDF schema of underlying database, from a registry of recommended schemas provided as guidance by Aggregation services. http://www.w3.org/DesignIssues/LinkedData
Multi-part work – data is meaningless without ancillary material (i.e. provides both context & meaning) – ancillary material in machine-readable formats Publish your DDI compliant XML codebook.
An extension of one of Tim O’Reilly’s 7 principles of Web 2.0 (2005) – Harnessing Collective Intelligence Bearing mind that there is a cost to keeping data closed !!! Open data are really open when they can be ‘always’ reused!
