Supporting price negotiations based on a DPP for a product that will be produced in the future

[zachzeus]

Some product claims may not be fully resolvable when the negotiation between buyer and seller is occurring. Is there a method that should or could be added to the protocol that will allow suppliers and consumers the ability to price the value of claims in the future.

DPPs are at the SKU or batch/item level. I think this question relates to proposed items or proposed batches where the items are known in advance.

For example: if I am negotiating a contract for future sale, I might make a basket of claims (and provide evidence) based on the information currently available, which the buyer uses to negotiate a price. When the sale is struck in the future, a different version of the basket of claims might be available. As a buyer, I will want to specify "same or better" for some claims.

The DPP link resolver may need access to the history of product passport versions. A DPP may need a reference "supersedes" the previous version of the DPP in a chain.

@monkeypants - what does it mean to close this issue? Is there an example of how we might use a DPP to address this?
This technique may also be useful for some of our circularity and 'late arriving data' scenarios.
