# Diabetes Data Types

This documents the diabetes device data types that Platform reads and stores. All events read and stored by Platform use the [JSON](https://www.json.org/) data interchange format and have a type field identifying the subcategory of event. The semantics of the other fields in each subcategory are generally defined individually per subcategory, but there are some [common fields](/docs/device-data/common-fields).
