These slides accompany the LDOW2010 paper "An HTTP-Based Versioning Mechanism for Linked Data". The paper is available at http://arxiv.org/abs/1003.3661. It describes how the combination of the Memento (Time Travel for the Web) framework, and a resource versioning approach that is aligned both with the Cool URI notion and with Tim Berners-Lee concept of Time-Generic and Time-Specific, yields the ability to collect current and prior versions of resource merely using "follow your nose" HTTP navigation. The proposed combination further extends the value of a URI, and allows the emergence of a novel realm of temporal Web applications.
