Hi Benjamin,
the approach #1 is the one that I'd go forward with. The emf resource
impl could be straight forward and just ignore the file contents. If you
register a service provider for that one, everything else should work
like a charm. There are no known problems with references that use
STRING as underlying representation.
Best regards,
Sebastian
