Interoperability for Accessing Versions of Web Resources with the Memento Protocol

Investigating bloom filters for web archives' holdings

“…Each time Google visits and indexes a page, the existing cached version is replaced 14 . Some noticeable early-stage approaches to support search and discovery of archival resources include IA's search 15 and the search tool powered by the Portuguese web archive Arquivo.pt 16 . Beyond that, most open web archives only offer search by URI and datetime in the past.…”

“…In addition, we see increasing use, analysis, and citation of web archive holdings by journalists, legal scholars, social scientists, linguists, historians, web and data scientists, and other interested users. In fact, an entire book chapter was recently dedicated to highlighting some of the novel research efforts enabled by web archives [15]. However, the level of diversity in the web archiving landscape and the broad spectrum of the user base also entails challenges.…”

Aggregator Reuse and Extension for Richer Web Archive Interaction

“…The concept of aggregation goes beyond the Memento specification by leveraging a similar structure to TimeMaps but allowing the URIs contained within the aggregated TimeMap to identify resources at multiple archives instead of a single archive. The Research Library at Los Alamos National Laboratory (LANL) deployed the original Memento aggregator [8,11], currently accessible through a web interface via the Time Travel service at https://timetravel.mementoweb.org/. This web service (Figure 2a) provides an HTML form field for a user to specify the URI-R and a datetime then uses temporal negotiation to query a set of archives and return links to the results (Figure 2b).…”
