# Licences and notices

The public datasets montaye’s reference data comes from, each with its licence, and the notice its licence asks to travel with the data.

Where montaye passes on what a dataset holds (a place’s name in an answer, for instance, copied from Unicode CLDR), the dataset’s licence may ask that its notice go with it. Each such notice is below, word for word as the dataset prints it and in the language it is written in.
