slug
The stable part of a record’s URL, derived from its title once and then never regenerated.
slug is the last segment of a record's address — the part after
/grants/. It is generated from the title when a record is first created and
then left alone.
Left alone deliberately. A slug that regenerated whenever a source retitled a notice would change the record's URL, break every link anyone had saved to it, and give a search engine two addresses for one page. A retitled notice keeps its slug and shows its new title.
Two records never share a slug. Where a title collides with one already in use, a suffix is added at creation rather than the earlier record being moved.
Shown as: the URL of the record page. When absent: never. A record without a slug has no address and is not published.
