About profile libraries

How it works

Libraries are used to manage configurations that are shared across multiple profiles. Consider the following points before you begin working with libraries:

• A profile can load one or more libraries, but libraries cannot load profiles or other libraries.
• A library is almost identical to a profile with the exception that a library can be imported into another profile.
• After an element from a library is imported into a profile, it cannot be edited.
• You can modify the tag configuration of an imported tag, as changes to tag configuration take precedence over library settings.
• After saving and publishing a profile with imported libraries, the resulting version and utag.js file represent the entire profile configuration.

Identify library elements in a profile

Consider the following when identifying library elements in a profile:

• Elements added from a library receive a label that indicates which library each element belong to.
• Tags added to a profile through a library receive a unique ID for that profile. This unique ID may be different than the ID that a tag receives when added to the library.
• Any tag, load rule, or extension added in a library will display as ON in the profile that loads the library. You cannot turn off a library-loaded element from a profile that loads the library.
• You cannot remove data layer variables imported from a library.
