# Example Data Schema Definition

Below is an example Data *Schema* definition for use in the Rhino Federated Computing Platform (FCP). A CSV version of the file is also available to download at the bottom of this article. This CSV file can serve as a template for you if you would like to create your Data *Schema* by uploading it from a file.
