I have uploaded a bunch of documents here. I don’t really want to spend too much time polishing the documents, as I am in the middle of developing an interactive demonstration for all the implementation project examples on this site. I have high hopes that the interactive demo, once active, will really clarify how everything fits together in the satconomy framework.
The Prowl implementation example has been revised to comply with the slightly extended version (see Prowl specs in the docs folder.) It shows an example for each of the three query strings that should greatly simplify the automation of inter-entity ledger reconciliation. The source code for the example is also available in the linked page.
