hREA adds ValueFlows queries and broadens its data checks

ValueFlows aims to make different economic software applications interoperable. With this update, applications can distinguish offers from requests and query each kind. hREA says interfaces built for it are compatible with other ValueFlows backends, including Bonfire, a modular, federated social platform.

The merged update adds new kinds of economic information and checks across hREA’s data. Those checks can reject writes that an older hREA release accepted, with a message naming the rule. The change also brings hREA’s implementation onto Holochain 0.7.

Before this update, hREA checked economic events and proposals, while other data types had permissive placeholders. New rules cover timing, non-negative quantities, required text, and fields that must remain unchanged during updates; they also check geographic coordinates and limit collection sizes. Transfer actions must name both a provider and receiver, while an intent’s minimum quantity cannot exceed its available quantity. For teams upgrading from happ-0.4.0-beta, a write the earlier conductor accepted may now be rejected with a message naming the rule.

Applications can distinguish offers from requests, and hREA’s GraphQL interface exposes queries for both. New records cover claims, spatial things and agreement bundles; economic events can link to settlements and reciprocal activity, while commitments can refer to reciprocal clauses. The branch also adds fields for resource substitution and an effort quantity for economic events. hREA says its interfaces are compatible with other ValueFlows backends, including Bonfire. The update also changes hREA’s adapter to read timestamp information from its new location in Holochain 0.7; previously, retrieved revision times came back null.
