 The first JSON Object should therefore be of type `"CityJSON"` and contain the necessary information.
 Notice that the properties `"CityObjects"` and `"vertices"` are mandatory (for the [JSON Object to be valid](https://www.cityjson.org/specs/#cityjson-object)) but should be respectively an empty JSON object and an empty array.

 ## Reading and writing CityJSONSeq with cjseq
 
 The software [cjseq](https://github.com/cityjson/cjseq) allows us to convert between CityJSON and CityJSONSeq (both directions).
