Retrieve a knowledge store item

The custom metadata of the source asset. Keys are strings; each value is a string, a number, a boolean, or an array of strings. The platform updates it when the user-defined metadata of the asset changes. To change it, use the PATCH method of the /assets/{asset_id}/user-metadata endpoint. To set custom metadata for the knowledge store item only, use item_metadata.

The custom metadata of the knowledge store item. Keys are strings; each value is a string, a number, a boolean, or an array of strings. It is separate from the custom metadata of the source asset. A change to the custom metadata of the source asset does not change this field. The same key can have different values in the metadata field and in the item_metadata field. You set it when you create the item or change it with the PATCH or PUT method of the /knowledge-stores/{knowledge_store_id}/items/{item_id}/item-metadata endpoint. This field is absent when no item metadata has been set.

Metadata that the platform extracts from the whole item, as defined by the enrichment configuration of the knowledge store. It contains the properties that have the granularity keyword set to video for a video, or to image for an image. Properties that have the granularity keyword set to shot do not appear in this field. Keys are the property names; each value matches its property definition. A property with no value is omitted. The field is present only when the item is ready and contains at least one value.
