Similar to #12596 and #12595 we want to allow users to update any data that is currently stored in the database. After identifying a user see #12596 and #12595, we could show a list of all known log tables and their respective columns. The Matomo user could see for example a list of all tables, when selecting a table, the user would see a list of all columns in that table. As most columns are defined in dimension classes, we actually have readable names and some description for each dimension there. If we don’t want to let users edit all fields, we could add a new property “holds potentially personal data” to show only these. However, easiest and most flexible way be to really show all fields.
We would need to see here as well regarding re-processing this data afterwards. In V1, we will not re-process historical data.
We ideally also have an event for plugins to support this feature in case they store personal data outside of log tables.
In V1 or V2 we could store data about how often this has occurred per day/week/month etc.
We would also support the Activity Log feature and trigger an event whenever some data was changed.
