HiQLCD-AL 2.0.0

Overview

What's new

HiQLCD-AL 2.0.0 contains 4,075 datasets (CUT_OFF), an increase of 3,038 over 1.0, covering aluminium products, alloying materials and processing activities. Both system models retain all historical dataset IDs.

• Non-ferrous Metals: Adds 3,037 datasets over 1.0 (CUT_OFF), represented by 铝合金, 铝箔, 铝铸轧带, 铝合金板 and 铝合金边框.

• Metal Alloys: Adds 165 datasets over 1.0 (CUT_OFF), with reference products 铝硅15, 铝铁10, 铝铜40, 铝铬5 and 铝锰10.

Changes

The comparison is from the historical 1.0 catalog to the published 2.0.0 catalog. CUT_OFF rises from 1,037 to 4,075 datasets (+292.96%); CONSEQUENTIAL rises from 995 to 4,026 (+304.62%).

Coverage changes

Reference-product counts rise from 16 to 32 in CUT_OFF and from 14 to 27 in CONSEQUENTIAL. Added coverage includes bauxite, cast-rolled aluminium strip, aluminium alloy frames and alloying materials. Both models continue to cover 37 geography codes, each adding 41 datasets under each of the existing 31 provincial codes.

Retained datasets keep the same reference products, reference quantities, units and geography codes. CUT_OFF has 4 activity-name revisions; each model has 6 retained records with revised description fields.

New dataset geographies (1.0 → 2.0.0)

New reference products (1.0 → 2.0.0)

Basis: the union of database-wide new Product UUIDs across comparable models, grouped by sector. Sector pages retain the within-sector set differences and names.

Data quality and documentation

Impact assessment

The impact assessment catalog contains 106 method entries, of which 44 have method names. The system models are CUT_OFF and CONSEQUENTIAL.

Known issues and limitations

Sector coverage uses overlapping tags.

Confirmed issues

No formal issue register has been obtained.

Documentation completeness (r1 field coverage)

Quality-score coverage counts populated fields; CUT_OFF includes 2 zero scores. Pending documentation: official release date, itemized revision notes, scoring scale and zero-value definition, method-implementation and characterization-factor revision notes, exact background version, and the AL 1.0 cumulative-result source. Migration references use database, version, system model and Dataset ID.
