Class transaction context
Milestone
https://opda.org.uk/pdtf/MilestoneTurtle ↓
Lifecycle event marking a significant point or stage in the progression of a property transaction, occurring either at a single instant or over a bounded interval.
Transaction lifecycle milestone. UFO Event particular; PROV-O Activity. Hybrid PROV-O typing per S007 Q2: instant milestones (instruction, offerAccepted, exchange) carry prov:atTime; interval milestones (completion-process, registration-process) carry prov:startedAtTime + prov:endedAtTime per Moreau W3C-grade discipline. Each Milestone Activity may pair with a prov:Plan carrying opda:plannedAtTime for expected-vs-actual variance (S007 Q6 Plan-vs-Activity reification).
