Petroleum and coal product data for AI identity records

This miscellaneous industry includes several product types, so a useful data proposal should name its exact material and decision. The Census manual provides the category scope. An original petroleum-wax exercise can focus on identity and source-document matching. Census petroleum and coal product scope
Write fictional wax product cards, a blend ledger and dispatch labels. Give two variants similar appearance and different internal identifiers. Ask an assistant which card supports each dispatch and which source is missing for a returned quantity. Include a supplier information sheet for the product family beside a batch-specific report. The review key should preserve the difference between general product context and evidence concerning the selected lot.
Label material form, variant, batch, returned material and source scope. Hold out an unfamiliar naming scheme for evaluation. Score family information used as lot evidence, invented return ancestry and wrong-variant matches separately. A photograph can show appearance while leaving composition and test properties dependent on their actual records.
Use original tables and harmless props. Real blend recipes, supplier contracts and laboratory documents need source-specific permission. Describe the precise identity task, evidence map and checked examples to prospective buyers. An accepted brief should determine whether further work needs historical documents, authorized new capture or another agreed source.

Original Fiund exercise
Same trade alias, different wax product
An invented wax ledger lists two products using one generic sales nickname.
| Record | Source | What it records |
|---|---|---|
| 1 | Product cards | Wax A17 is block form; wax A71 is pellet form. Both use nickname Clear. |
| 2 | Blend ledger | Lot L3 logged as A71. |
| 3 | Dispatch label | L3, nickname Clear, carton art says block. |
Question for the model
Which identity does the ledger support, and what needs reconciliation?
Show the reference answer and checks
The lot ledger identifies L3 as A71; record 1 maps A71 to pellet form. Record 3's block descriptor conflicts with that mapping, and the shared nickname Clear cannot resolve it. Flag the form conflict and request independent identity evidence before using the dispatch label.
- Joining on nickname alone
- Treating a printed form descriptor as physical inspection
Fields to preserve
- canonical_product_id
- Disambiguates shared aliases
- form_descriptor
- Records a material form separately
- label_conflict
- Retains discrepancies for review
Test another case
Provide a renamed product whose canonical ID remains stable; track alias validity dates without splitting lot lineage.
No real wax formulations, blend settings, plant data or product-use claims.
