Re: [tz] technical details for today's code and data release

But it seems to indicate that we should go with two-faceted tags (tz_codeX_dataY), to make this clear.

I'd disagree. That would mean that to check out codeX, you would need to enumerate the list of tags to determine a matchign dataY. Better, I think, to have a codeX tag and a dataY tag and suffer the fact that a checkout of one will give you a close-but-potentially-unexpected other. --jhawk@mit.edu John Hawkinson
