Owen, If you remember we said last fall that that the aim was to provide for this kind of tripping and so the answer is yes to both questions. Based on our experimentation thus far at LC, I would not expect the trips either way to be lossless, however, in some cases, a trip could actually add clarity to the source data.
We are planning to make downloadable some transformation pipeline software (Python and XQuery versions) at the end of this week or early next that programmers can use to experiment as we have been doing. They can tweak and change the code around and experiment with their ideas. In January we also hope to have some transformation services open for experimentation. I emphasize that these tools are to enable experimentation, not the final word on a or the transformation.
The Early Experimenter team will be meeting here next week and we hope that some interesting data will come out of what they have done over the last 2 months that we and they will share with the community.
Your questions are good ones and good reminders that the past does exist.

There are two questions in my mind around this, and if it is at all possible some explicit statements from LoC about these would be useful (to me at any rate):
1) Is the intention that it will be possible to automatically create Bibframe serialisations from existing MARC21 records
2) Is it the intention to be able to roundtrip records between Bibframe serialisation and a MARC21 record?
I have to admit that I've tacitly assumed (1) because I'm not sure how else it would be possible to transition from MARC21 in any forseeable timescale. (2) I suspect will be difficult to achieve, if indeed it is seen as desirable at all.
