Abstract: An insurance policy is stored (101) as a plurality of discrete temporally-sequential policy data revisions. A legally binding revision for a first given date is then determined (102) by identifying all policy data revisions effective on the first given date and choosing a most temporally recent policy data revision temporally prior to a second given date. When a new policy data revision is (103) temporally subsequent as compared to a first policy data revision and also comprises a legally effective date range preceding at least in part an effective date range of the first policy data revision, legally non-overlapping policy data revisions are created (104) for each legally overlapping effective date range as exists between the new policy data revision and all temporally preceding revisions. Each newly-created legally non-overlapping policy data revision comprises changes introduced by the new policy data revision and at least one temporally preceding policy data revision.

Abstract: An insurance product model comprising insurance policy metadata is provided (101) in a computer memory. The insurance policy metadata may comprise, at least in part, data that describes information that comprises a given corresponding insurance policy. A computer then serves to substantively interpret (102) this insurance product model to facilitate obtaining supplemental policy-specific data. The supplemental policy-specific data and the insurance policy metadata comprise separate and discrete data models and may, if desired, be stored (103) separately from one another. So configured, these teachings further support using (104) the insurance product model and the supplemental policy-specific data to facilitate an insurance-related action.
