+Tracking issue: https://github.com/comit-network/comit-rs/issues/917[comit-rs#917]
+
+== Context
+
+In order to move forward easily with Bobtimus prime we should define the siren json document of how a IN_PROGRESS response look like in each state of accept and decline, i.e. when you call GET /swaps/ for Bob.
+
+Siren repository: https://github.com/kevinswiber/siren/
+
+The prototype must conform to https://github.com/kevinswiber/siren/blob/master/siren.schema.json[Siren JSON schema]
+
+== Research
+
