`version_status` Field

Data license customers have an additional field appended to each data license profile: a version_status for the ID. This object tracks the previous and current dataset version, any other persistent IDs that were merged into this record using improved entity resolution, and the status of the record. Records still existing in the dataset can have one of the three following statuses: added, updated or unchanged. Records can also have a null version_status if they are not in any of our license datasets.

ID Changelog

We also provide an additional changelog that includes all six statuses (with moved, opted_out and deleted records included) as a flat file in a public AWS bucket here. Here is a description of each status:

Status	Frequency	Description
`added`	common	This record was not in a previous build.
`deleted`	very rare	This ID was removed due to a source-level removal.
`moved`	variable	Less common than `added` and `updated` and will vary from build to build based on linkage improvements.
`opted_out`	very rare	This ID was removed due to an opt-out on our website.
`unchanged`	common	No new data sources have been added to the record. However, parsing and standardization improvements may have been made.
`updated`	common	A new data source contributed to this record.

Additional Metadata

Some of the statuses listed in the table above will also contain the following metadata:

Metadata Field	Corresponding Version Status	Description
`contains`	`updated`	The persistent IDs of any records that existed in a previous version and have been merged before or during the current version.
`to`	`moved`	The persistent ID that this record has been assigned in the current version.
