title: Uniform and Robust Access to Resource Versions
creators: Herbert Van de Sompel
abstract: The Memento protocol tightly integrates the Web of the Present and that of the Past, making it possible to seamlessly navigate between both. The protocol defines an interoperable approach to access versions of a resource in web archives or content management systems such as wikis that leverage the URI of that resource and the datetime of the required resource version. Technically, the Memento protocol is an extension of HTTP that is fully based on the primitives of Web interoperability: URIs, resource representations, links, content negotiation. The tutorial will give an in-depth insight in various aspects of the Memento protocol that meanwhile has been published as RFC 7089.
