"Metart" could be a combination of "meta" and "art". "Meta" often refers to something self-referential or about itself, so "metart" might mean art that is about art or art that reflects on art. Then there's "inna r". That part is unclear. Maybe it's another term in a specific language or a typo. Inna is a name, but maybe it's part of the title or the artist's name. Let me check possible spellings.
