Content base types

Optimizely Content Management System (CMS) (SaaS) registers a set of base schema types that content types inherit from. The following diagram examines the type hierarchy. It includes examples of the user-defined content types NewsPage, LandingExperience, ImageMedia, TeaserBlock, and HeadingElement to show how user-defined content types relate to the base types.

Note

The base types are prefixed with _ to distinguish them from user-defined content types.

Example queries

The base types can be used to query over sets of content types. To query overall content types, you can use the common base type _Content:

query AcrossAllContent {
  _Content
  {
    items{
      _metadata {
        displayName
      }
    }
  }
}

To search over content types of a specific base type, like Image, then you can use the base type _Image:

query AcrossAllImages {
  _Image
  {
    items{
      _metadata {
        displayName
      }
    }
  }
}
