Learn how to use the collections section of the CONTENTdm Server Administration to add, move, configure, or delete collections.

Collections are the basic components of a CONTENTdm site. A collection consists of the digital files and their associated metadata that have been uploaded to the server and approved. Before they can be viewed by end users, the collections must also be indexed.

A collection must be added in the server administration. When you create a new project in the Project Client to upload files or edit metadata, you need to associate this project with a particular collection.

 Note: For information about configuring a collection, please see Access and edit collection configuration.

Add a new collection

When a new collection is added, CONTENTdm creates a data structure that allows digital items to be imported, metadata to be stored, and an index to be created.

We recommend that you don't go beyond 500 collections to ensure performance, but we do not have an upper limit for collection count.

Add a new collection

  1. Open CONTENTdm Administration and select the server tab.
  2. Click collections.

  4. From the drop-down menu for Create a new collection using, choose the collection template you want to use (for example, Simple Dublin Core).
  5. Enter Collection name.
     Note:  The maximum number of characters allowed in a collection name is 80.  The collection name cannot include any of the following characters: \ / : * ? " < >  |
  6. The Collection alias field is pre-filled with a system-generated alias. Leave it be or pick your own custom alias. If you choose to use a custom alias, pay attention to the on-screen instructions:
    • Collection alias is used in the URL as a unique collection identifier. For example, 'oclcsample' is the alias for this collection: https://cdmdemo.contentdm.oclc.org/digital/collection/oclcsample.
    • The collection alias cannot be modified once the collection has been created.
    • The collection alias can only contain alphanumeric characters (a-z and 0-9) and the '-' (hyphen) and '_' (underscore) characters.
    • The collection alias must start with a letter (a-z).
    • The collection alias must not exceed 13 characters in length.
    • The collection alias can contain lowercase and uppercase characters and it is case-sensitive. For example, you can use 'VanGogh' as a collection alias but be aware that requests for 'https://yoursitedomain/digital/collection/vangogh' will then result in an error because the letter case does not match.

       Note: Please read and Change collection aliases retcontactingy before contacing OCLC Support about changing an existing collection alias.

  7. Click add.

The new collection will appear in the Collections list.
