Dear All,
Priority registration for the next DPC briefing day, 'Links That Last: Linked Data, Persistent Identifiers and Digital Preservation', at Lucy Cavendish College Cambridge on 19th July 2012 is now open for members of the Coalition.
Widely-distributed, highly-volatile and tightly-integrated data streams create a particular challenge for preservation. One could be forgiven for thinking that digital preservation was principally concerned with safeguarding of self-contained packets of information that may have interdependencies but which are so carefully tucked into stand-alone files that they have a sort of independence and autonomy which ensures their integrity. This has never been the case. Nonetheless recent developments in data presentation have shown the potential that can be gained from liberating data from clumsy format wrappers and enabling retrieval and integration of individual data points. The emerging ‘Linked Data’ approach enables new types of interaction with and between structured data and it challenges existing paradigms of data sharing. It also challenges us to think about preservation in new ways: it creates the potential for long chains of interdependencies and it means we need to think all the more carefully about provenance and authenticity. The question arises as to whether Linked Data will simply deliver a new generation of broken links – stifling the innovation it promises and creating the conditions for new and avoidable forms of disenfranchisement.
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.
This briefing day will introduce the topics of persistent identifiers and linked data, discussing the practical implications of both approaches to digital preservation. It will consider the viability of services that offer persistent identifiers and what these offer in the context of preservation; it will review recent developments in linked data, considering how such data sets might be preserved; and by introducing these two parallel topics it will go on to consider whether both approaches can feasibly be linked to create a new class of robust linked data. Based on commentary and case studies from leaders in the field, participants will be encouraged to consider practical implications for their own work and new directions for research and development in the field.
Members have access to priority registration at no cost online at: http://www.dpconline.org/events/details/47-linksthatlast?xref=49
Non-members will be invited to register from Monday 11th June
All best wishes,
William
