Specification
Offer Management is RCP-57, proposed on RESO Transport.
Read and discuss the proposal on RESO Transport: issue 252
The proposal text lives at proposals/offer-management.md in RESOStandards/transport. Review and discussion happen there, and that copy is authoritative.
Status
The proposal is open. A reference implementation exists and is described on the Tools page, and a playground runs the activity layer in your browser.
Two implementations advance a standard, and more is better. If you are building against this, say so at transport@reso.org.
