Hello, all. I'm working on some projects where we are trying to define
formats and guidance for metadata *profiles*. You may have seen the
profiles that were created at one point for BIBFRAME (I can't find them
at the moment on the new site) - they were more "list-like" than the
fancy BF-lite site, but mostly the same idea. Profiles often are a
simple list of data elements or properties, sometimes with a bit more
info like cardinality.
What I want to find are some examples of documentation aimed at those
creating the metadata records that explain what goes into the metadata,
and hopefully some rules like "this has to be a date in the format
yyyy-mm-dd". I'm guessing that folks using systems like contentDM may
have something of this nature. Obviously, the whole RDA enchilada would
be way too much to chew on at this point. If you can point me to
documentation that you have created or use, I would appreciate it. If I
decide to do more with it than ruminate I will let you know.
I want to note that part of the goal is to link metadata schema
documentation and metadata user documentation with a validation language
like ShEx. If you want to know more, ping me, but we should have more
to say after the Dublin Core meeting in D.C. later this month, where we
are having a whole day on profiles, Oct 27, called "taming the graph".
 You can find some profiles based on the W3C standard DCAT here:

may find some other interesting links on that page.
