Jeff, I don't think that the question of programming tools is the hard 
one. There are lots of programming tools. 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.

And as for that practice - I'm not saying that catalogers have been 
sloppy or remiss. 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.

We need a future data carrier, but I caution that we have to continue 
to expect a great deal of variability in the data itself. 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.
