Yes, this. There can definitely be a difference between the internal
formats of the system and what is exposed as linked data. There's a lot
that one might not choose to expose - I happen to know folks who work on
banking data, and although they use linked data internally they
obviously don't expose it as LoD. For libraries, it may only make sense
today to expose data that has widely known identifiers, like VIAF or
DOI. I'm just riffing here, but I think this is an area that needs more
thinking on.
