IResultAttributeHeaderItem.uri property

URI of the attribute element.

Signature:

uri: string;

Remarks

This is essentially a primary key of the attribute element. It can be used in places where attribute elements have to be exactly specified - such as positive or negative attribute filters.

It is up to the backend implementation whether the URI is transferable across workspaces or not in the data distribution scenarios. In other words, if a data for one attribute (say Product) is distributed into multiple workspaces, it is up to the backend whether the URIs of the elements will be same across all workspaces or not.

Recommendation for the consumers: URI is safe to use if you obtain in programmatically from this header and then use it in the same workspace for instance for filtering. It is not safe to hardcode URIs and use them in a solution which should operate on top of different workspaces.

Note that this can actually be null on some backends if your data contains NULL values. We will change the type of this to string | null in the next major (since it is a breaking change), but for now, if you expect NULLs in your data, treat this as string | null already.
