If you want to know what new Authority Documents to add to a specific instance of your software, you must query your customers' shared Authority Document lists and check each list associated with your instance to see if there is a change in the list. Customers may add or delete Authority Documents from their lists.
To learn about content updates and additions:
- Make an API request(s).
- Process the date_updated field of all shared Authority Document lists associated with your instance to see if anything has been updated since the last time you made a request to the same endpoint.
- Compare the Authority Documents in each of the updated shared Authority Document lists contained in the API response to discern if an Authority Document has been added.
Note: Customers may add an Authority Document that was added 5 years ago to their list, for this reason please do not rely solely on date_released fields for Authority Documents and date_added for Common Controls and Citations.
- Compare the date_modified fields of all the Authority Documents, Common Controls, and Citations in each of the updated shared Authority Document lists to find out what has been modified within the list.
