Feature

The new optional sourceSpecific field is now available in Organizations Ownership endpoint responses.

The new optional sourceSpecific field is now available in Organizations Ownership endpoint responses.
The field conveys extra source-specific information such as
- Number of shareholders
- Purpose
- Registration date
- Industries
- Addresses
- Unidentified shareholder counts
The field can appear
- At the top level of the response
- Inside the top-level entity (for example: attribute.sourceSpecific)
This functionality is backwards-compatible. If no extra data exists, the object is null.
Fields inside sourceSpecific vary by source but are stable for the same source.
