Hello Murdo

Editing metadata on the NBN Gateway is currently disabled whilst the Gateway is transferred over to the new system. This is to make sure that the new system has the latest metadata and no changes have been made in the "old" system which are then not transferred over. Editing metadata will become available on the new system as soon as possible.

The main route to change metadata through user account is no longer available but as you say there are other links to seemingly allow editing of dataset metadata that are still available. However it is not be possible to change the metadata through these links as the underlying procedure to write to the database has been disabled. I have flagged this up with the Gateway developers as it would be clearer if these links were also not available in this interim period, though please note development work is focused on the releasing the current functionality in the new site

Best wishes

Graham
