pub const PORTRAIT_SOURCE: &str = "wikidata";Expand description
The name a portrait reached through Wikidata is stored under.
Not wikipedia, even though the same entity document is the source of
both: an article’s prose and an entity’s P18 image are two different
claims, fetched to answer two different questions, and a record that
carried both could not be re-fetched for one without silently dropping the
other — Sources::set replaces a record whole, it does not merge fields
into it. Keeping them as two records under two names is what lets
fetch --summaries and fetch --portraits each redo their own work
without undoing the other’s.
