The subject disclosure pertains to relationships between items. Relationships between items can be defined external to the items themselves thereby providing a modular flexible and extensible system. For instance relationships between items can be defined in a class that includes methods for returning particular elements or values in accordance with a specified relationship. Moreover a compiler or like system can be extended to accept relationship expressions in a simple property format and direct such calls to specific methods.
