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) Overall quality scores are counted from process documents; exchange data quality score coverage counts datasets with at least one scored exchange. Pending documentation: itemized mappings to yearbook parameters and parameter references for targeted photovoltaic and blast-furnace revisions. | Worksheet | Field | Rows with missing values or components | Total rows | | ---------------------- | ---------------------------------------- | -------------------------------------: | ---------: | | Cut-Off AO | Technology Level | 32,609 | 32,609 | | Cut-Off AO | Product Classification | 32,609 | 32,609 | | Cut-Off AO | Product Information | 32,609 | 32,609 | | Cut-Off AO | CAS Number | 32,341 | 32,609 | | Cut-Off AO | Cut-Off Classification | 32,609 | 32,609 | | Consequential AO | Technology Level | 31,032 | 31,032 | | Consequential AO | Product Classification | 31,032 | 31,032 | | Consequential AO | Product Information | 31,032 | 31,032 | | Consequential AO | CAS Number | 30,866 | 31,032 | | Consequential AO | Cut-Off Classification | 31,032 | 31,032 | | 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 | Unit Name | 15 | 909 | | Intermediate Exchanges | CAS Number | 903 | 909 | | Intermediate Exchanges | Comment | 909 | 909 | | Intermediate Exchanges | By-product Classification | 909 | 909 | | Intermediate Exchanges | CPC Classification | 909 | 909 | | Intermediate Exchanges | Product Information | 909 | 909 | | Intermediate Exchanges | Synonym | 909 | 909 | | Elementary Exchanges | Unit Name | 1 | 4,794 | | Elementary Exchanges | CAS Number | 597 | 4,794 | | Elementary Exchanges | Comment | 4,794 | 4,794 | | Elementary Exchanges | Synonym | 4,794 | 4,794 | | Elementary Exchanges | Formula | 573 | 4,794 | | Impact Categories | Method ID has missing components | 163 | 1,920 | Source: [Database Overview：Field Availability](/files/hiqlcd/1.3.0/revisions/20261106T193638Z/hiqlcd_Database_Overview_v1.3.0_r20261106T193638Z.xlsx) ## Citation hiqlcd, version 1.3.0.
