OR2012 Developer Challenge:
A Thing of Dreams – A Time Machine
Dave Tarrant from the University of Southampton presented his idea for a repository time machine at the DevCSI Open Repositories 2012 Developer Challenge.
In his original entry, Matt gave the following description of his idea:
Linked data is one strongly supported way for exposing data. The problem is that a lot of data being exposed is not static, it changes! Over the last couple of years a lot of suggestions have been made on how to handle non static linked-data for single URIs. In this presentation we show how by using one such method we can enable a “time-machine” interface to be built to browse linked-data through time. That’s all very pretty but this also means you can use memento to request the data at a URI from a specific time. The next stage is to support memento headers for SPARQL queries, enabling full historical query of data that will require interconnection and full inference.
Can you say scale!
