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: original characterization-factor sources, independent method-implementation versions, formal method revision notes, and expert review notes for indicators with large changes. Historical result statistics retain the significance selection and rounding precision of the source report. | Worksheet | Field | Rows with missing values or components | Total rows | | ---------------------- | ---------------------------------------- | -------------------------------------: | ---------: | | Cut-Off AO | Technology Level | 46,060 | 46,060 | | Cut-Off AO | HIQ Industry Classification | 2 | 46,060 | | Cut-Off AO | Product Classification | 46,060 | 46,060 | | Cut-Off AO | Product Information | 46,060 | 46,060 | | Cut-Off AO | CAS Number | 38,492 | 46,060 | | Cut-Off AO | Cut-Off Classification | 46,060 | 46,060 | | Consequential AO | Technology Level | 44,319 | 44,319 | | Consequential AO | HIQ Industry Classification | 3 | 44,319 | | Consequential AO | Product Classification | 44,319 | 44,319 | | Consequential AO | Product Information | 44,319 | 44,319 | | Consequential AO | CAS Number | 36,948 | 44,319 | | Consequential AO | Cut-Off Classification | 44,319 | 44,319 | | EN15804 AO | Technology Level | 46,095 | 46,095 | | EN15804 AO | HIQ Industry Classification | 2 | 46,095 | | EN15804 AO | Product Classification | 46,095 | 46,095 | | EN15804 AO | Product Information | 46,095 | 46,095 | | EN15804 AO | CAS Number | 38,429 | 46,095 | | EN15804 AO | Cut-Off Classification | 46,095 | 46,095 | | Geographies | Latitude | 35 | 420 | | Geographies | Longitude | 35 | 420 | | Geographies | Geography Classification | 420 | 420 | | Geographies | Contained and Overlapping Geographies | 420 | 420 | | Geographies | Parent Geography | 1 | 420 | | LCIA Methods | Method Version | 42 | 42 | | LCIA Methods | Status | 42 | 42 | | LCIA Methods | HiQLCD Documentation | 42 | 42 | | LCIA Methods | Further Documentation | 42 | 42 | | LCIA Methods | Links to Characterization Factor Sources | 42 | 42 | | Impact Categories | Resources - Emissions - Total | 676 | 676 | | Impact Categories | Main impact/damage category | 676 | 676 | | Impact Categories | Inventory - Midpoint - Endpoint - AoP | 676 | 676 | | Impact Categories | Area of Protection (AoP) | 676 | 676 | | Impact Categories | Used in EN15804 | 676 | 676 | | Impact Categories | Category name in method | 676 | 676 | | Impact Categories | Indicator name in method | 676 | 676 | | Impact Categories | Unit in method | 676 | 676 | | Intermediate Exchanges | Unit Name | 370 | 1,315 | | Intermediate Exchanges | CAS Number | 1,153 | 1,315 | | Intermediate Exchanges | Comment | 1,315 | 1,315 | | Intermediate Exchanges | By-product Classification | 1,315 | 1,315 | | Intermediate Exchanges | CPC Classification | 1,315 | 1,315 | | Intermediate Exchanges | Product Information | 1,315 | 1,315 | | Intermediate Exchanges | Synonym | 1,315 | 1,315 | | 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 | Source: [Database Overview：Field Availability](/files/hiqlcd/1.5.0/revisions/20261106T193638Z/hiqlcd_Database_Overview_v1.5.0_r20261106T193638Z.xlsx) ## Citation hiqlcd, version 1.5.0. Specify the system model, dataset and source when citing results. See [citation format](/en/resources/citation). ## Sources Sources and exact file revisions are recorded below each table or statement. File definitions are available in [File definitions](/en/resources/file-definitions).
