You can never give a 100% guarantee to that anyway, and user-agents have to
cope. I say go with the HTTP URIs.

You can provide a stable HTTP URI that you use in your RDF and which when
dereferenced redirects to whatever the external source is currently using to
identify the resource. You could even redirect or provide a representation
yourself depending on what sort of representations is accepted by the
user-agent.
