Permalinks

Avalon provides hooks that allow institutions to define permalinks (e.g., using a Handle server, DOI, or other durable link generating system) to resources. These links show up on the item/preview page in the Share this resource tab.

Permalinks are generated only for published Media Objects. When a Media Object is published, or a published Media Object is modified, Avalon makes sure that a permalink exists for the Media Object and for each of its Master Files (tracks, sections, etc.).

To define how permalinks are generated, create a file in config/initializers (e.g., config/initializers/generate_permalink.rb) following this template:

Permalink.on_generate do |obj|
  # Create a permanent link resource that will resolve/redirect to obj
  # and that resource as a URL string. e.g., 
  return "http://permalinkresolver.example.edu/media/#{obj.pid}"
end
