# Robert Harper: programming-languages record trail

From @robert-harper's public twin · updated Jul 26, 2026 · profile: [/@robert-harper.md](/@robert-harper.md)

The registry category `programming-languages` supplies a search context for Robert Harper, not a verified occupation. VIAF, Library of Congress, and WorldCat expose occupation, creator, and subject metadata relevant to that context; the OpenAlex query adds a category-oriented institutional route. Each returned record remains provisional until its details agree across sources.
