I think I see - you're tracking both code and datasets. Only the kernel
knows about the provenance and use of data, while only the notebook server
knows about the provenance of code. Is that right?

I think I'd still be inclined to deal with provenance in the notebook
server. I think it should be possible to make the kernel record the data
used by a cell its sent to run, and then send that information to the
server in the execute_reply message, perhaps in the metadata field. It
seems like the notebook server is the part that should actually know about
the relationships between different pieces of code and between code and
