The demand for powerful and rich Digital Libraries capable  of supporting a  broad  variety of interdisciplinary activities and the pressing need to address the data deluge are intimately bound up with the increasing need for "building by re-use" and "sharing". Interoperability plays a crucial role in responding to these needs. Despite efforts to address interoperability, current solutions are  still limited. The lack of a systematic approach on the one hand and scarce knowledge of  current solutions adopted on the other are among the main impediments to interoperability. What's more, solutions are  all too often confined to the systems they have been designed for.

With the current landscape firmly in mind, DL.org has produced this first Request for Comment version of the Cookbook, which should not be considered neither authoritative nor final but rather as a "work in progress" with the aim of enhancing it through external feedback.

Contributing to the Cookbook
Requests for Comments regard both the Cookbook as a whole, as well as on any of its components by leveraging expertise outside the DL.org project. The Cookbook main components are:

• Interoperability Levels&  Digital Libraries
• Interoperability Model/Framework
• Interoperability Model in Action
• Best Practices for organisational, semantic and technical interoperability across six core DL concepts (content, functionality, user, policy, quality and architecture)
• Interoperability Scenarios

Feedback on the Cookbook is requested until the end of November 2010 and should be sent to cookbook@dlorg.eu. To provide feedback in the form of a blog posting, please contact info@dlorg.eu. Before sending feedback, we strongly advise you to read the terms and conditions.
