(By Jakob Lesage): "A noun is reduplicated if its root is fully or partially repeated. The word class of the outcome of the process is not relevant, as long as the root is a noun. Full repetition of already inflected nouns or units larger than a root does not trigger a 1 for this feature. This feature only targets productive reduplication. Reduplication in closed classes (e.g. kinship terms) is not relevant. Lexicalized examples are irrelevant."
When the noun root is fully copied, the two elements need to occur adjacent to each other. This is part of the Grammaticon definition of "reduplication", and maybe it is implicit here.
