Known issues and limitations

Sector tags overlap. Inventory revisions are counted by changes in core inventory fields; metadata revisions are counted separately.

Confirmed issues

No formal issue register has been obtained.

Documentation completeness (r1 field coverage)

Score coverage counts populated fields. Pending documentation: a comparable preceding catalog, early background-version records, and a reconciliation of the official counts of “27 key sectors”, “more than 1000 products” and “more than 1500 specific process technologies” with the current catalog.
