Entity updates are available starting in ODK Central v2023.5.

Additionally, we have

  • updated the "Additional columns" sheet in the XLSForm template to reflect the new entity_id and update_if columns for the entities sheet.
  • published a tutorial. At the end of the tutorial you'll have a form that community members can use to report problems and another form that staff members can use to see problems on a map and address them. Once problems are addressed, they are no longer shown on the map.
  • updated documentation to describe updates and conflicts.
  • added entity updates to the ODK XForms spec.

We hope you find this helpful and look forward to your feedback about this feature area!
