The HTTP-based Memento framework bridges the present and past Web. It facilitates obtaining representations of prior states of a given resource by introducing datetime negotiation and TimeMaps. Datetime negotiation is a variation on content negotiation that leverages the given resource's URI and a user agent's preferred datetime. TimeMaps are lists that enumerate URIs of resources that encapsulate prior states of the given resource. The framework also facilitates recognizing a resource that encapsulates a frozen prior state of another resource.

The WARC (Web ARChive) file format offers a convention for concatenating multiple resource records (data objects), each consisting of a set of simple text headers and an arbitrary data block into one long file. The WARC format is an extension of the ARC file format (ARC) that has traditionally been used to store “web crawls” as sequences of content blocks harvested from the World Wide Web. Each capture in an ARC file is preceded by a one-line header that very briefly describes the harvested content and its length. This is directly followed by the retrieval protocol response messages and content.

Filtering obligations -Undermining the foundations of Open Access7.The provisions of Article 13 threaten the accessibility of scientific articles, publications and research data made available through over 1250 repositoriesmanaged byEuropean non-profit institutions and academiccommunities. These repositories, which are essential for Open Access and Science in Europe, are likely to face significant additional operational costs associated with implementing new filtering technologyandthe legal costs of managing the risks of intermediary liability. The additional administrative burdens of policing this contentwould add to these costs. Such repositories, run on a not-for-profit basis, are not equipped to take onsuch responsibilities, and may face closure. This would be a significant blow, creating new risks forimplementing funder, research council and other EU Open Access policies.

Why does archive.is not obey robots.txt?

par ces usages, c’est-à-dire par la génération de ces formes intermédiaires encore à interpréter, que l’archive peut accéder au statut d’objet culturel.

ce passage de la donnée à des formes intermédiaires, qui sont des représentations de l’archive

il est un outil de relecture des données selon l’intentionnalité de son usager.

les différents dispositifs d’éditorialisation participent de la médiation de la base de données en mettant à disposition des usagers des interfaces sur lesquelles agir, c’est-à-dire sur lesquelles exécuter des requêtes, annoter, collecter, partager.
