Jeff,

You can have a data standard and a standard way to exchange data, even 
in the linked data world. I personally don't call it a record. Some 
people might. But I don't think it matters what we call it. And 
application profiles are descriptions of graphs that can include 
constraints that are related to data creation but that do not constrain 
use on the open web. Tom Baker and I will have a discussion paper out 
on that in June, leading up to the discussion at DC2013 [1]. I think 
your knowledge of OWL would be an asset to that discussion, since we 
definitely have not solidified our ideas - we want a lot of input. 
Also, that discussion will of necessity inter-twine with the discussion 
on quality assurance in RDF [2] that is taking place right after the 
DC2103 meeting.

I also hear people talking about "application profiles". I could name others. Same things? A record by any other name would still smell.

What will be difficult will be understanding and working with the huge variety in data practices - most of which are undocumented, and some of which are idiosyncratic if not down-right unfortunate (such as the addition of ISBNs for different manifestations to a single MARC record, which has been much discussed here). It's one thing to address a data standard - it's another thing to address the actual practice.

They have worked, often in isolation, to try to satisfy a whole panoply of requirements: requirements related to sharing; requirements related to service to a specific population of users; requirements related to systems functionality that is beyond their control.

Rather than making "rules" for how to convert from MARC to BIBFRAME, we should be creating flexible conversion routines that libraries and systems can use with knowledge of their own practices and needs, and then we need to talk collectively about coordinating in a shared environment. I actually think that the *intention* of BIBFRAME is to facilitate that flexibility, and maybe we have been remiss in thinking that the LC MARC-to-BIBFRAME process = BIBFRAME. This is why I would like there to be BIBFRAME discussions that are not solely "how to transform MARC." That's only one role that BIBFRAME will fulfill, I hope.
