Last week, some of us from The National Archives were privileged to spend a day in Cambridge with over 50 people from the heritage spheres gathered for the Digital Preservation Coalition event, Links that Last.
(For those new to the concept of linked data, I have no hesitation in recommending this Wikipedia article: ‘linked data describes a method of publishing structured data so that it can be interlinked and become more useful. It builds upon standard Web technologies such as HTTP and URIs but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers.’)
As the Links that Last programme puts it:
‘The emerging ‘Linked Data’ approach … challenges us to think about preservation in new ways. Simultaneously, the digital preservation community has put considerable effort into the development of persistent identifiers, services that seek to ensure that essential links are not lost and … that the highly distributed contexts in which information is presented are protected against the vagaries of time and obsolescence’.
