Quantifying the captures of a URI over time is useful for researchers to identify the extent to which a Web page has been archived. Memento TimeMaps provide a format to list mementos (URI-Ms) for captures along with brief metadata, like Memento-Datetime, for each URI-M. However, when some URI-Ms are dereferenced, they simply provide a redirect to a different URI-M (instead of a unique representation at the datetime), often also present in the TimeMap. This infers that confidently obtaining an accurate count quantifying the number of non-forwarding captures for a URI-R is not possible using a TimeMap alone and that the …

[First paragraph] A Composite Memento is an archived representation of a web page with all the page requisites such as images and stylesheets. All embedded resources have their own URIs, hence, they are archived independently. For a meaningful archival replay, it is important to load all the page requisites from the archive within the temporal neighborhood of the base HTML page. To achieve this goal, archival replay systems try to rewrite all the resource references to appropriate archived versions before serving HTML, CSS, or JS. However, an effective server-side URL rewriting is difficult when URLs are generated dynamically using JavaScript. …
