Provides data for Template:Metadata id.
The first parameter is the name of the entity. The
inherits parameter is the name of the entity it inherits from (which, for the root entity, is blank). The
start_at variable indicates the starting ID (defaults to 0); it should not be used if the inherited entity is on the page (this is only useful for the root entity and on the pre-release page).
Behavior changes if
meta_prerelease is defined; this template then supports optional
pre_start_at parameters, which should only be specified if the values changed. The template will also check if the entity has already been included on the page and decide whether to use a relative link or directly link to Entity metadata.
