Introducing Cemmento: A digital preservation tool for annotations | Martin Paul Eve | Professor of Literature, Technology and Publishing

"Cemmento does the following:

1. When a URL is passed, it checks whether a version exists in the storage backend (in this case, the Internet Archive) with the querystring ?cemmento.
2. If a version does not exist, Cemmento requests the internet archive to store a copy.
3. Cemmento redirects the user to the earliest copy on the internet archive, using a Via service to automatically load a commenting/annotation engine (in this case, Hypothesis)."
