Separate normalization from invention
A supplier sheet may express package size in one column, selling unit in another and dimensions inside prose. Normalization should preserve those relationships. Converting a pack of twelve into a single-unit product, or treating packaging dimensions as product dimensions, can create operational errors even when every output field passes a type check.
A catalog task needs to identify the source of each changed attribute, apply approved units and vocabularies, and flag unsupported values. Generated descriptive copy belongs to a different policy boundary from factual attributes. An absent material specification or compatibility claim should remain absent or enter review rather than be completed from a model’s general knowledge.
Review a change set before applying it
Represent a candidate as a field-level difference against a specific catalog version. Distinguish a new product, an update to an existing variant and a supplier alias for an existing item. Retain stable identifiers through the transformation so downstream inventory and order references remain attached to the correct product.
Validation should cover allowed category attributes, unit conversion, uniqueness constraints and relationships among parent products, variants and packs. For concurrent edits, compare the expected version before applying changes. An editor’s recent correction must not disappear because a batch was generated against yesterday’s snapshot.
| Attribute class | Validation rule |
|---|---|
| Identifiers and variants | Resolve against stable existing keys |
| Measurements and units | Convert only through approved explicit mappings |
| Category vocabulary | Accept listed values or request review |
| Descriptive text | Separate generated wording from verified factual claims |
Treat catalog approval and publication separately
An accepted change in a product-information system does not establish that every storefront or marketplace received it. The contract should name the destination and the effect being confirmed. A first workflow can stop at a reviewable draft change set, leaving channel publication to existing processes.
A useful pilot measures attribute preservation, invalid-value detection and operator corrections across representative categories. Include discontinued items, multi-pack variants and conflicting supplier identifiers. Confirm that a failed row stays visible instead of dropping out of an otherwise successful batch. Each publication destination needs its own acknowledgment and reconciliation rules.
