neighbor

Offer, Contract and Transaction - This model may observe requested, quoted, administered or transacted amounts, but the commercial record owns negotiation, agreement, performance and legal effect.
Invoice and Payment - Invoiced and paid amounts are external accounting or settlement events; they may evidence price but do not become appraisal or index conclusions.
Asset, Liability, Product, Service and Right - The valued subject and interest retain external identity, physical or legal properties and lifecycle while this model owns only the scoped value assertion.
Currency and Exchange Rate - Currency codes and rate observations are external masters; a derived conversion retains original amount, rate binding, time, direction and rounding.
Official Statistics WM-DAT-002 - This model specializes price-index semantics and calculations while Official Statistics owns programme authority, release governance, statistical quality and general observation-vintage lifecycle.
Dataset, Report and Evidence - Datasets, valuation reports, workfiles and snapshots are referenced artifacts; none replaces the logical value assertion, method or immutable revision.
