org.apache.stanbol.entityhub.servicesapi.model.Representation.addReference()
Adds an reference to the field. @param field the field @param reference the string representation of the reference. Note thatthe value will be interpreted as a "reference" so there might apply some rules about the format of the string. Regardless of the implementation any valid URI and URL need to be accepted as a valid reference value @throws NullPointerException @throws IllegalArgumentException if null or an empty string is parsed as field or reference
