I was just looking through the receipt work, good stuff there. I
recently started compiling examples of trade examples, looking at the
potential for proposing a microformat, supporting the trading of goods
and record thereof.
http://microformats.org/wiki/trade-examples

Clearly, the receipt work is much more mature the trade investigations
to date. That said, it seems to me it would make sense to merge
efforts.

The trade pipeline is (roughly):
Consideration > Purchase > Fullfillment > History

Examples of artificats generated at each phase (artifacts are
generated on both ends of the transaction, they are broken out as
Buyer / Seller):
Wishlist / Estimate > Receipt / Invoice > Shipment Record / Bill of
Lading > Transaction Record

There is significant overlap in the data elements for each of these
records. It would seem to me that one microformat could support the
sum of these phases.

Thoughts?
