A submission tried to record "source type" for this entry, but the atlas does not yet track that as a property of a source entry. The underlying fact may be well attested; what is missing is a place in the atlas's own model to hold it, not the fact itself.
What would resolve this A decision on whether source type should become a property this atlas tracks for source entries. Editors added encyclopedia as a live source-type value; the original fact can now be entered.
Resolution Closed 2026-08-23 by lane w-vocabfix1: editors added encyclopedia as a live source-type value for source entries (content.PropertyEnumValue), matching the value PhilosophyAtlas already carries. The original submission that hit this gap can now be entered under the correct type. · 08/23/2026 12:00:00 AM
