A new version of the Wayback code has been released that is fully compatible with the most recent version of the Memento Internet Draft. It is available in the wayback GitHub repository and is operational at the Internet Archive's Wayback Machine. A Memento-compliant version of the Wayback code has been available since the early days of the Memento effort. But, since those days, the protocol specification has evolved and the Wayback code needed updating.
A command line Memento client, named mcurl (after curl), has been released by Ahmed AlSum, PhD student of Michael L. Nelson of the Computer Science Department of Old Dominion University. This client is available via http://www.cs.odu.edu/~aalsum/projects/mcurl.html and is compatible with version 07 of the Memento Internet Draft, which is available at http://www.ietf.org/id/draft-vandesompel-memento-07.txt.
Today marks the open source release of our SiteStory transactional web archiving solution. The solution is compatible with the Memento framework and its current implementation can be used to archive Apache web servers.
Information about SiteStory is available via http://mementoweb.github.com/SiteStory/. A Google group dedicated to discussions pertaining to SiteStory is at https://groups.google.com/forum/#!forum/sitestory.
Robert Sanderson and Herbert Van de Sompel will do presentations related to Memento at the 2012 General Assembly of the International Internet Preservation Consortium that takes place in Washington (DC), May 1-4 2012.
The EU-funded BlogForver project is all about archiving blogs and keeping them accessible for the long term. For their February 2012 BlogForever Consortium meeting participation from the Memento team was requested in order to clarify how Memento's approach for Web time travel can help the project achieve its goals. Herbert Van de Sompel will travel to Berlin, present on Memento, and engage in discussions with project representatives.
A new version of the Memento Internet Draft is published. Major changes are:
- Added description about Mementos of HTTP responses with 3XX, 4XX and 5XX status code.
- Clarified that a TimeGate must not use the "Memento-Datetime" header.
- Added text stating that it is not recommended to have an Original Resource and its TimeGate coincide in Memento implementations because of caching issues that may arise.
At the 2011 STM Innovations, Herbert Van de Sompel discusses problems related to accessing temporal states of the Web-based scholarly record, and how Memento and pro-active Web archiving can address them. In good Science-Technology-Medicine information industry tradition, the presentation is hidden behind a username/password.
Herbert Van de Sompel presents a keynote about Memento at the Future of the Past of the Web conference at the British Library, London, UK.
Michael Nelson presents Memento's concepts for time travel on the Web at the 2011 meeting of the National Digital Information Infrastructure and Preservation Program in Washington, DC. His students also present Memento-related work, including the ArchiveFacebook FireFox add-on aimed at self-archiving personal Facebook pages.
