Missing Link proposal

I felt like mentioning that, in addition to the Memento protocol and the mset document mentioned by Ryan, there is also the Missing Link document that emerged last year as a result of work in the Hiberlink project. The document provides:

• A motivation for annotating links with attributes aimed at increasing link robustness,
• A couple of proposals for such attributes.

The Missing Link document precedes the mset document and hence needs to be read as such.
