How to fix this issue

Your dataset is missing the entry-date column.

The Conservation area guidance explains how to fix the issue:

entry-date

The date the record was last updated.

If the entity has never been updated, enter the same date as start-date.

Write in YYYY-MM-DD format.

Example:

2022-12-20

With dates, some data is better than no data, so:

  • 2022 is fine
  • 2022-12 is better
  • 2022-12-20 is brilliant

How to improve Historic England’s data
