Meta-data for currency of rules
Include a meta-data item for effective dates/times for rules
Include (optional) meta-data indicating effective start and end date/time for a rule or ruleset.
It can be omitted for those environments for which it is not relevant
Position in the DC structure
Supports CSFs ‘Coverage’ and ‘Low Cost of Implementation’ (provides simple basis for handling change of rules over time without requiring full version control capabilities).
Also the basis for supporting:
- Retrospective analysis: “what would the outcome have been if this state of affairs had occurred yesterday?”
- Future simulation - if not-yet-effective rules are stored.
Potentially major benefits for (very) limited impact.
