Linked Data? Open Data? Linked data – a technique for creating data which joins up with data from other data provider’s unique identifiers. Open data - publishing data with a license which permits re-use, akin to creative commons for creative arts and to 'open source' software. RDF - a way of structuring data as a list of facts and globally unique identities for things. Easy to merge lists of facts from multiple sources. LINKS: http://is.gd/WmZfq1
URIs to identify everything URIs look like a web address, but (sometimes) identify a real world thing such as Equipment – http://id.southampton.ac.uk/equipment/E0672 Facilities – http://id.southampton.ac.uk/facility/F0041 Campuses – http://id.southampton.ac.uk/site/1 Organisations (and parts thereof) – http://id.southampton.ac.uk/ – http://id.southampton.ac.uk/org/FP LINKS: http://is.gd/WmZfq1
How Open Data can Support Big (research) Data Open Datasets as Big Data Taxonomy Aggregated Open Data becomes Big Data Encourages formation of standards
"The greatest crisis facing us is not Russia, not the Atom Bomb, not corruption in government, not encroaching hunger, nor the morals of the young. It is a crisis in the organization and accessibility of human knowledge. We own an enormous "encyclopedia" - which isn't even arranged alphabetically.
Our "file cards" are spilled on the floor, nor were they ever in order. The answers we want may be buried somewhere in the heap, but it might take a lifetime to locate two already known facts, place them side by side and derive a third fact, the one we urgently need. Call it the crisis of the Librarian. We need a new "specialist" who is not a specialist, but a synthesist. We need a new science to be a perfect secretary to all other sciences." - Robert A. Heinlein, 1950.
