Re: is/hasAdaption

Ah, OK. You are saying that generic "is related to" metadata can be used,
and that we don't need accessibility-specific versions of those
relationships. 

I guess I would leave this to the search engines participants to weigh in
on -- does it improve search to know more specifically that this is an
accessibility adaptation of that, or is it fine to know they are related,
and then go dig through other metadata to figure out the relationship? To
be fair, a "has adaptation" link may not say much about what kind of
adaptation is at the end of the link. But "is adaptation" metadata is
probably accompanied by some details about what kind of adaptation this is.
