An appropriate version of a service for use by a service requestor is selected based on metadata. A request for a service object provided by a service is received from a service requestor. Multiple, different versions of the service are determined, and metadata associated with the multiple, different versions of the service is examined to select a version of the service that is compatible with the service requestor. The requested service object is instantiated from the version of the service that is compatible with the service requester. The service requestor is enabled to access the instantiated service object.
