properties

A string map of item-specific metadata. Each element in the map consists of a key-value pair. For example, {"numberOfRatings": "12"}.

The keys use camel case names that match the fields in the schema for the Items dataset. In the previous example, the numberOfRatings matches the 'NUMBER_OF_RATINGS' field defined in the Items schema. For categorical string data, to include multiple categories for a single item, separate each category with a pipe separator (|). For example, \"Horror|Action\".
