> As mentioned in #45, should we add a contract requirement that all RDFTerm
> instances (and Triple?) be implemented as immutable objects?

> +1, if we say SHOULD. But only the exposed RDFTerm++ methods need to be
> immutable - so this should probably go into each of their descriptions. So if
> I have a getDatabaseThingie() method that can be mutable.

> The value of stating that the objects must be immutable is decreased if it
> only applies to the results of the API methods. A useful goal would be to
> ensure that the entire object is immutable to give a guarantee about
> threadsafety, but that may be too much for all implementations to support.
> Just stating that the results of the visible API methods are immutable
> doesn't help much. It is also not likely to apply to the methods that return
> Optional, as to enable serialisation, the actual field may not be an Optional
> itself in most cases.
