ALL_USAGE

const Wikibase\Client\Usage\EntityUsage::ALL_USAGE = 'X'

Usage flag indicating that any and all aspects of the entity were (or may have been) used.

DESCRIPTION_USAGE

const Wikibase\Client\Usage\EntityUsage::DESCRIPTION_USAGE = 'D'

Usage flag indicating that one of the entity's descriptions were used.

This would be the case when showing the descriptions of a referenced entity. Note that descriptions usage is typically tracked with a modifier specifying the language code.

LABEL_USAGE

const Wikibase\Client\Usage\EntityUsage::LABEL_USAGE = 'L'

Usage flag indicating that one of the entity's labels were used.

This would be the case when showing the label of a referenced entity. Note that label usage is typically tracked with a modifier specifying the label's language code.

OTHER_USAGE

const Wikibase\Client\Usage\EntityUsage::OTHER_USAGE = 'O'

Usage flag indicating that some aspect of the entity was changed which is not covered by any other usage flag (except "all").

That is, the specific usage flags together with the "other" flag are equivalent to the "all" flag ( S + T + L + O = X or rather O = X - S - T - L ).

This currently covers alias usage and entity existence checks.

SITELINK_USAGE

const Wikibase\Client\Usage\EntityUsage::SITELINK_USAGE = 'S'

Usage flag indicating that the entity's sitelinks were used as links.

This would be the case when generating language links or sister links from an entity's sitelinks, for display in the sidebar.

Note

: This does NOT cover sitelinks used in wikitext (e.g. via Lua). Use OTHER_USAGE for that.

STATEMENT_USAGE

const Wikibase\Client\Usage\EntityUsage::STATEMENT_USAGE = 'C'

Usage flag indicating that certain statements (identified by their property id) from the entity were used.

This currently implies that we also have an OTHER_USAGE or an ALL_USAGE for the same entity (STATEMENT_USAGE is never used alone).

TITLE_USAGE

const Wikibase\Client\Usage\EntityUsage::TITLE_USAGE = 'T'

Usage flag indicating that the entity's local page name was used.

This would be the case when linking a referenced entity to the corresponding local wiki page.
