Collection Content Model


Creating a Collection

  • Log in to You will be automatically redirected to your institution's homepage.

  • Click the "Manage" tab.


  • Under "Overview", select "Add an object to this Collection".


  • Select "Islandora Collection Content Model" from the "Select a Content Model to Ingest" dropdown menu and click "Next".


  • The next page will be where you will set up your collection policy. Create a PID for your collection by entering your namespace number followed by a colon ( : ) and an identifier. For example, a PID for UConn Archives and Special Collections would start with 20002 and be followed by the name or number of the collection. The UConn Activism Collection object has the PID of 20002:Activism.


  • Uncheck the box and you will see a list of Namespaces and Content Models to include in your collection. Select your institution's namespace and choose the content models that you will need to ingest content into your collection.

  • After selecting the content models, scroll down and click "Next".

  • Click "Next" and choose your preferred MODS form.

Choosing your MODS form

Please select the correct MODS form you wish to use, as the different forms have defaults built into them. Most CTDA users, including users managed by Bibliomation, should use the CTDA Collection MODS Form or the CTDA Item MODS form. Users from University of Connecticut and the Connecticut State Library should select the appropriate MODS form for their collection.



A namespace is a series of 5 digits the CTDA uses to identify an institution. All institutions should have received a namespace from the CTDA prior to adding content to the repository. If you are unsure of your namespace, please consult the namespace listings here.


What is a PID?

The PID is an internal unique and persistent identifier assigned by Fedora to digital objects.

  • Click "Next" and you will be taken to CTDA MODS form, where you will fill out information about your collection.


  • The first required field you will need to enter is the title of your collection.


  • The next required field is "Digital Origin". You should leave "reformatted digital" if the objects you are going to add to this collection have been scanned or transcribed from physical media.


  • The third required field is the "Held By" field. Select your institution from the dropdown menu.


  • The final required field is the "Rights" field. Choose your institution from the dropdown menu. If you do not have a customized rights statement, select "Creative Commons NC-BY".


  • Finally click the "Ingest" button.

  • You will be taken to your new collection page. From here you can add objects into your collection by clicking the "Manage" tab.
