What it is Filled
A material batch or lot is a defined quantity of material produced or processed under uniform conditions and identified as one unit for quality and traceability. It links a quantity of material to its production run, inputs, tests and release status; a single serialised item or the material type itself is not a batch.
In scope
- Qualified lot identity, material reference, boundary rule and aliases
- Lot-specific quantity assertions, packaging membership, production and genealogy references
- Sampling and test evidence links, disposition assertions, storage history, expiry/retest and trace coverage
- Local revision, access, retention and interoperability requirements
Out of scope
- Substance, formulation and engineered-material master definitions; recipe design and production control
- Sample, laboratory test, measurement, shipment, container and custody-event master lifecycles
- Executing physical operations, issuing release or recall decisions, certifying safety or operating an inventory ledger
- Hazardous or controlled material operating instructions; only policy and authorized profile references are allowed
Why it exists Filled
Batches and lots of material produced under uniform conditions, for quality and traceability.
Distinguishing features Filled
- A batch is a quantity of material treated as one unit; a serialised item is identified individually.
- It is an instance of production, unlike the material or product type it belongs to.
- Batch release and recall decisions are made on the batch, so the quality status belongs to it.
- Shipments carry parts of batches; the shipment and the batch are separate records.
What robots and AI may and may not do Filled
Must not
- Change a batch status to released without the authorised release decision.
- Alter test results or batch genealogy after release.
- Merge or split batches without recording the new identifiers and links.
- Hide a recall or hold from parties who received the batch.
- Extend an expiry date without an approved retest.
Only with a human decision
- Releasing or rejecting a batch.
- Issuing a recall or hold.
- Approving rework or reprocessing of a batch.
May
- Record batch numbers, quantities, inputs and test results.
- Trace a batch forward to shipments and backward to input lots.
- Report batch status, expiry and storage conditions.
- Flag a batch whose tests are missing or out of specification.
Moral aspects Filled
- Accurate batch traceability is what makes fast and targeted recalls possible.
- Falsified batch records can put patients, consumers and workers at risk.
- Over-broad recalls waste material when genealogy is incomplete.
Who is affected
- Consumers and patients
- Manufacturers and quality staff
- Customers and distributors
- Regulators
Owners Filled
Steward

- Production or receiving recorder
- Supply evidenced origin and quantity assertions within delegation.
- Laboratory evidence reviewer
- Assess sample and test relevance without altering laboratory masters.
- Records and access officer
- Govern retention, recipient access, exports and disposal.
Master systems
- Manufacturing execution system
- Enterprise resource planning batch records
- Laboratory information management system

- WM-MAT-007 Laboratory Test / Analysis - Test master and method references, without operating a laboratory. Profile binding and version require validation before integration.
- WM-MAT-008 Observation / Measurement Record - Measurement results and environmental observations remain external masters. Profile binding and version require validation before integration.
- WM-FLW-013 Supply-chain Trace / Chain of Custody - Custody and shipment evidence links; no transfer execution or ownership inference. Profile binding and version require validation before integration.
- Production event and quality decision masters - Reference actual occurrence and authorized disposition, without adopting their execution functions. Profile binding and version require validation before integration.
- world-m1-material-and-substance - A batch is a quantity of a defined material.
- wm-mat-007-laboratory-test-analysis - Batch release relies on laboratory tests.
aligned
- EPCIS - Conceptual event and quantity alignment; implement and test a version-pinned mapping before claiming conformance.
- SOSA/SSN and PROV-O - Conceptual sample, observation and provenance alignment; links do not certify truth or representativeness.
neighbor
- WM-MAT-001 Chemical Substance; WM-MAT-002 Engineered Material; WM-MAT-003 Mixture / Formulation - Reference the applicable material definition and version. A lot may instantiate a substance, engineered material or mixture; none of these is the lot identity.
- WM-MAT-005 Lab Sample / Specimen - A sample has its own identity and sampling lineage. Lot-level inference must cite representativeness assessment; sample lifecycle remains external.
- WM-MAT-007 Laboratory Test / Analysis; WM-MAT-008 Observation / Measurement Record - Reference test and observation masters and their revisions. This model records relevance and decision support, not laboratory execution or raw-result replacement.
- WM-FLW-013 Supply-chain Trace / Chain of Custody - Keep lot-specific links and known trace coverage. Custody events, shipments and title transfers have separate masters; a location observation proves none of them by itself.
- Production event, logistics unit and quality decision - A persistent lot is neither the transformation that created it nor a container or decision. One lot may span containers and locations; one container may contain several lots.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- A batch is identified by its batch or lot number together with the producer and product identifier.
- GS1 Application Identifier (10) carries the batch number in barcodes, with GTIN for the product.
- Expiry and production dates are often encoded alongside the batch number.
Direct properties required Filled
- Quantity of the batch in mass, volume or count with its unit.
- Results of specified quality tests, each with method, unit and specification limits.
- Manufacturing date and expiry or retest date.
- Storage conditions such as temperature and humidity ranges required to keep the batch in specification.
Recognition required Filled
- A batch is recognised by the batch number on its labels and containers, with product and dates.
- Often confused with a shipment, a pallet or a single serialised item.
Capabilities and actions required Filled
- Batches can be traced forward to customers and backward to input lots.
- Batches can be held, released, rejected or recalled as one unit.
- Batches can be split or merged with recorded genealogy.
Hazards and failure modes required Filled
- Contaminated or out-of-specification batches reaching users.
- Mix-ups of batches with similar labels.
- Incomplete genealogy that slows recalls.
Standards and interfaces required Filled
- GS1 General Specifications for batch numbers in barcodes and EPCIS events.
- ISA-88 batch control and ISA-95 enterprise-control integration.
- Good manufacturing practice batch records in regulated industries.
Context of use required Filled
- Batch records are required by law in pharmaceuticals, food and many chemical industries.
- Used in manufacturing, quality control, logistics and recalls.

Open questions
- Resolve source version pins and direct reachability, especially the EPCIS URL/PDF mismatch, and obtain independent external review before canonical promotion.
- Implement and test nested fields and mappings using collision, mixed-container, continuous-production, invalid-sample, concurrent-hold, partial-trace and correction-after-release fixtures.
- Review material-sector and jurisdiction profiles, continuous-flow allocation, recycled-material accounting and controlled-material policy boundaries with qualified custodians.
- Independent external provider review is absent; the local self-audit cannot replace it.
- Direct HTTP checks were not attempted under the owner-declared sandbox block. Current reachability, response hashes and source revision reconciliation remain unverified.
- EPCIS URL includes 2.0.1 but the retrieved PDF identifies Release 2.0, June 2022. Resolve this before any executable mapping claim.
- Nested instance schemas, exact unit conversions, inventory balance rules and executable acceptance fixtures remain to be implemented.
- Sector-specific continuous-flow allocation, recycled-material accounting, food and other regulatory profiles require additional research.
- No complete identifier encoding, laboratory accreditation, safety certification or legal compliance assessment is provided.
