Dryad's content will be replicated through the CLOCKSS network.
CLOCKSS will crawl the Dryad site and harvest publicly-viewable content. Data files will only be replicated in CLOCKSS once any embargo has expired.
Each quarter, Dryad will publish a set of manifest pages that list content newly available in Dryad.
There is a command line process that generates a manifest page. The manifest page will be a static page. It will contain links to all "new" data packages. A new data package is a package that meets at least one of the following conditions:
- The package was archived since the previous manifest page was generated.
- The package, or one of its constituent files, was modified since the previous manifest page was generated.
- At least one file in the package has come out of embargo status since the previous manifest page was generated.
- A new version of the package has become available since the previous manifest page was generated.
