A wide range of presentations were given on the full range of digital preservation topics. Four representatives from the ODU Web Sciences and Digital Libraries group attended to present their research and recent work in one of various realms within the field.

The Web Archive Cooperative (WAC) held its 2012 Summer Workshop June 29–30 at Stanford University Palo Alto, California. The workshop focused on the challenges (and some solutions) of providing easy access to the World’s web archives. The WS-DL Research Group had six members in attendance.

Version control services such as GitHub also allow temporal access, but using a version number instead of datetime. Harihar Shankar of the Los Alamos National Laboratory (LANL) Research Library presented Memento and a Memento/GitHub proxy prototyped at LANL. The proxy enables access to GitHub projects through datetime. For many use cases, datetime is much simpler that Git’s 25-hex-character commit id.
