midtlige

Could you clarify what "midtlige" refers to? It isn’t widely known in English, and a precise wiki-style article would depend on the context. For example, is midtlige a term from a specific language (Danish, Norwegian, Swedish, etc.), a geographical place, a cultural or historical concept, a scientific or mathematical term, a profession, a product, or a fictional concept? If you provide the intended context or scope, I can write a concise, neutral wiki-style article (under 300 words).
