MilestoneKindScheme
opda:MilestoneKindScheme MilestoneKindScheme
Summary
Method/plan codes for the procedural milestones authorising stages of a Transaction Activity (instruction → offerAccepted → exchange → completion → registration). [UFO Method/plan code]. Codes are ratified by ODR-0007 §Q2 transaction-lifecycle pattern; each milestone corresponds to a stage transition in the PDTF process. Steward: Guizzardi (S007 Q2). Concept tier — Milestone →

|---|---|---|---|
completion | completion | Completion; legal title transfers; keys handed over | ODR-0007 §Q2 |
exchange | exchange | Contracts exchanged; transaction binding on both parties | ODR-0007 §Q2 |
instruction | instruction | Property instructed to market by Seller; transaction lifecycle begins | ODR-0007 §Q2 |
offerAccepted | offerAccepted | Offer accepted by Seller; transaction enters Under Offer phase | ODR-0007 §Q2 |
registration | registration | Registration completed at HM Land Registry | ODR-0007 §Q2 |
Cardinality discipline
No core-tier attribute in the emitted TBox currently binds this scheme directly. Used by Milestone instances to discriminate the milestone Kind at the typed-class level (each canonical milestone may bind to a future Milestone sub-class via skos:exactMatch when the lifecycle taxonomy expands). Closed scheme — strict five-stage lifecycle.
