 # Intro to Islandora CLAW
 
 Islandora CLAW is the project name for development of Islandora to work with Fedora 4. The current release of Islandora, known as 7.x-1.x, works as a bridge between Drupal 7.x and Fedora 3. Put simply, Islandora 7.x-1.x is middleware between Fedora 3 and Drupal 7.x, sometimes expressed as a hamburger:

 ### Interoperability
 
-Islandora CLAW works with the [Portland Common Data Model](https://github.com/duraspace/pcdm/wiki), "a flexible, extensible domain model that is intended to underlie a wide array of repository and DAMS applications." What does this mean in practice? Objects stored in Islandora CLAW will have a a data model that can be recognized by Hydra and other custom Fedora 4 based repository heads, and vice versa. By working together with the Hydra and Fedora communities, we can leverage a broader community of developers, librarians, and other digital repository users to build better tools and share reosurces.
