Source label corrections scoped to one item

Source: R/table_mappings.R
polity_label_item_corrections.Rd

Rows a source files under ANOTHER territory's label for one item, published by whep-polities. An alias maps a label to a polity with no item dimension, so it cannot say that Mitchell's pre-1910 "south africa" sugar cane is Natal's while the other items under that label are the Cape's. Each rule replaces the label before resolution; resolve_polity_label() applies them when it is given item.

Usage

polity_label_item_corrections

Format

A tibble with one row per rule. It has zero rows when the shipped snapshot was taken from a whep-polities revision that published no rules. Columns:

  • source: Source slug the rule applies to.

  • source_label: The label the source files the rows under.

  • item: The item, exactly as the source writes it.

  • year_start, year_end: Inclusive year range.

  • unit, indicator: Scope of the rule. NA (blank upstream) means any; when set, the row's own unit / indicator must equal it. All NA in a snapshot taken before whep-polities introduced the columns.

  • correct_label: The label to resolve instead.

  • polity_code: Where correct_label resolves in the same upstream revision, or "UNROUTED" when the rows belong to no polity and resolve_polity_label() leaves them unassigned.

  • observed_rows: Source rows the rule relabels upstream.

  • issue: The whep-polities issue that decided the rule.

  • evidence: Why the rows belong to the other territory.

Details

A row matches a rule when source, source_label (normalised as the alias map's labels are) and item all match and the row's year lies in [year_start, year_end]. Rows without a year are never corrected, and rules do not chain. A rule with unit or indicator set also needs the row's own unit / indicator to equal it.
