| Subject: | Custom metadata fields |
At present, many pages on OGL have pseudo-metadata like "nearest tube station" which has to be entered into the main text box. It would be advantageous to be able to define arbitrary extra metadata fields with unique names to which user-visible labels would be assigned, and which would subsequently appear in the edit page.
Should an arbitrary field subsequently be removed by a site maintainer, I would suggest that any data entered into nodes using it should be retained in the database, in case the maintainer changes their mind.
