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. | Worksheet | Field | Rows with missing values or components | Total rows | | ---------------------- | ---------------------------------------- | -------------------------------------: | ---------: | | Cut-Off AO | Technology Level | 31,368 | 31,368 | | Cut-Off AO | Product Classification | 31,368 | 31,368 | | Cut-Off AO | Product Information | 31,368 | 31,368 | | Cut-Off AO | CAS Number | 31,368 | 31,368 | | Cut-Off AO | Cut-Off Classification | 31,368 | 31,368 | | Consequential AO | Technology Level | 29,699 | 29,699 | | Consequential AO | Product Classification | 29,699 | 29,699 | | Consequential AO | Product Information | 29,699 | 29,699 | | Consequential AO | CAS Number | 29,699 | 29,699 | | Consequential AO | Cut-Off Classification | 29,699 | 29,699 | | Geographies | Latitude | 15 | 393 | | Geographies | Longitude | 15 | 393 | | Geographies | Geography Classification | 393 | 393 | | Geographies | Contained and Overlapping Geographies | 393 | 393 | | Geographies | Parent Geography | 1 | 393 | | LCIA Methods | Method Name | 63 | 107 | | LCIA Methods | Method Version | 107 | 107 | | LCIA Methods | Status | 107 | 107 | | LCIA Methods | HiQLCD Documentation | 107 | 107 | | LCIA Methods | Further Documentation | 107 | 107 | | LCIA Methods | Links to Characterization Factor Sources | 107 | 107 | | LCIA Methods | Method UUID | 1 | 107 | | Impact Categories | Resources - Emissions - Total | 1,920 | 1,920 | | Impact Categories | Main impact/damage category | 1,920 | 1,920 | | Impact Categories | Inventory - Midpoint - Endpoint - AoP | 1,920 | 1,920 | | Impact Categories | Area of Protection (AoP) | 1,920 | 1,920 | | Impact Categories | Used in EN15804 | 1,920 | 1,920 | | Impact Categories | Method | 1,155 | 1,920 | | Impact Categories | Category | 1,105 | 1,920 | | Impact Categories | Indicator | 1,140 | 1,920 | | Impact Categories | Unit | 1,158 | 1,920 | | Impact Categories | Category name in method | 1,920 | 1,920 | | Impact Categories | Indicator name in method | 1,920 | 1,920 | | Impact Categories | Unit in method | 1,920 | 1,920 | | Intermediate Exchanges | CAS Number | 857 | 886 | | Intermediate Exchanges | Comment | 886 | 886 | | Intermediate Exchanges | By-product Classification | 886 | 886 | | Intermediate Exchanges | CPC Classification | 886 | 886 | | Intermediate Exchanges | Product Information | 886 | 886 | | Intermediate Exchanges | Synonym | 886 | 886 | | Elementary Exchanges | Unit Name | 1 | 4,795 | | Elementary Exchanges | CAS Number | 598 | 4,795 | | Elementary Exchanges | Comment | 4,795 | 4,795 | | Elementary Exchanges | Synonym | 4,795 | 4,795 | | Elementary Exchanges | Formula | 574 | 4,795 | | Impact Categories | Method ID has missing components | 163 | 1,920 | Source: [Database Overview：Field Availability](/files/hiqlcd/1.1.0/revisions/20261106T193638Z/hiqlcd_Database_Overview_v1.1.0_r20261106T193638Z.xlsx) ## Citation hiqlcd, version 1.1.0.
