This operation adds an object to a collection of objects and returns an indicator of success. OpenRegistry only supports the registration of objects in the form of text strings or URLs as part of this operation. While other types of objects can be accomodated within an OpenRegistry, their registration requires the implementation of a custom interface that is not specified as part of this standard.
