Questions about ONIX

Can someone fill me in about ONIX?  Namely, are companies, as opposed to
libraries, the ones generally using it for bib data creation?  Does it cost
to use it?  Not knowing the answers to those first questions, I will also
ask: does it seem that this is a standard that we in libraries would adopt
to create bibliographic records?  From the little I know of it, it seems to
be extensive in terms of what you can include--is that true?  Aside from
being extensive (if it is), is it also extensible?  Would it serve our
patrons' traditional and emerging needs?  How easy or hard is it to use for
all concerned, i.e. catalogers, database people, etc.?

Thanks,
Sue Ann Gardner
