In accordance with embodiments, there are provided mechanisms and methods for providing linked property types in a content management system. These mechanisms and methods for providing linked property types in a content management system can enable users to specify a new property definition type, which refers to another node instance in the content management system. By specifying a link property definition type on a type, the user can then relate a node instance of the modeled type (link source) to any other node instance (link target) in the system. For example, a user can create a type Article with property definitions such as title, body and authorLink. The authorLink property definition can be a link type property definition. Then the user could define an Author content type. When an instance of an Article is created (anArticle), the authorLink property associated with anArticle could refer to a node instance of an Author.
