Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
| dq_identity | all inventory rows | Supply actual physical identity, native restrictions and provider-boundary match; distinguish ordinary auxiliary UUID gaps from missing endpoint/route/basis. | complete native records; supplier specifications; applicability decision |
| dq_coverage | all processes | Cover full campaign including zero output and actual service interval; preserve old cohorts and every inherited exchange vector and denominator. | complete records; genealogy; stock and vector reconciliation |
| dq_measurement | all inventory rows | Retain calibration, unit/state conversions, raw data, missingness, non-detects and uncertainty; never replace an unknown with a model-specific public default. | calibration; raw records; conversion and uncertainty files |
| dq_no_approval | first_release | Declare actual configuration/drawing/quality criteria and available independent test evidence. Literature examples and engineering validation do not approve compliance or science. | drawing; acceptance basis; actual tests; explicit limitations |
9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
| validate_identity | all inventory rows | Confirm each real article/preparation/species and boundary before binding a UUID. Retain every native name qualifier, supplied form, CAS, route, geography in the complete flowInformation, type, reference-property index and all secondary properties; a name/classification hit is insufficient. Product/Waste/Elementary and air/media distinctions remain separate. Unbound auxiliaries keep precise atomic identities and supplier evidence requirements. | ifc-plastic-products-2007 |
| validate_reference | first_release | Require the actual complete helmet configuration and first-release mass trace with independent count reconciliation; unassembled shell or suspension cannot be the terminal reference. Actual quality/certification evidence belongs to the data producer. No public example mass, joules, package count, supplier assertion or another model certificate establishes this article's compliance or lifetime. | jsp-evo3-spec-2016; vitoppe-helmet-manufacturing |
| validate_balance | all processes | Reconcile total mass and relevant element inventories independently from measured chemical speciation. Keep non-overlapping material/WIP, FG, water-loop, equipment-charge and each packaging ledger. At manufacture Q already contains new closing FG; at the service gate retain gross shipments and returns; at the combined gate cancel internal transfers. Explain uncertainty rather than forcing closure with an invented species, reaction water or loss ratio. | ifc-plastic-products-2007; ilcd-general-2010 |
| validate_raw_once | all inventory rows | Retain raw meter/weighing records and original units, convert real rates/integrated volumes correctly, allocate the raw exchange vector, and apply calc_reference exactly once. Collection aggregation and card amounts only reference that same result. Preserve original Q_h for every old cohort and inherited vector; Q_h=0 retains real burdens but produces no unit result. Engineering checks do not establish science, translation or actual-factory approval. | ilcd-general-2010 |
| validate_complete | all processes | Before a quantitative dataset is complete resolve actual missing operations, supplied formulations, auxiliaries, output destinations, species/compartments, historical vectors and uncertainty. Do not mark a real unknown as zero or exclude it to satisfy a checker. Core endpoint/route/basis failure blocks applicability; an auxiliary UUID gap alone does not change the method into a different product. | ifc-plastic-products-2007 |
| validate_asset_manufacture_conservation | existing capital/reusable manufacture attribution | For every included capital/reusable manufacture attribution verify same-asset continuity, whole installed service in matched units, all historical/current beneficiaries, prior assigned manufacture shares and cumulative share <= 1. Reject a reset by period, cohort, provider, owner or repair. Check distinct real replacement and incremental repair/treatment vectors separately and preserve gross physical mass. A missing denominator, unexplained previous allocation or incomplete beneficiary ledger requires explicit review and an unavailable final attributed amount; structural inspection cannot claim empirical completeness. |
