“… As a librarian, I would like to tag resources into curated lists … so that I can feed these these lists into subject guides, course reserves, or reference collections.

“I'd like these lists to be portable (into Drupal, LibGuides, etc.) and durable.

“I'd like these lists/tags to selectively feed back into the discovery environment without having to modify the catalog records.”

Requirements:• Create and manage tags/annotations in any client or environment• Retrieve tags/annotations to display in any client• Chosen identifiers, not necessarily catalog ids

Need: • A model for annotations• A format to serialize them into• A protocol to transfer the serializations between systems• Storage for tags/annotations• Restful searching for tags/annotations• Implementations!
