This page contains an overview of Unknown fields encountered in lists of monuments. These are fields in the list templates which are not understood by the Monuments database and are often an indication of malformatted templates or the introduction/deprecated of some template parameters. All the pages and the statistics are updated on a regular basis by a bot based on the data in the monuments database.

How does it work?

Every night a ErfgoedBot updates the Monuments database with all the lists we have on Wikipedia. When the bot interprets the templates on these pages it has a list of template parameters that it expects. If it encounters any other parameters in the row or header templates it makes a note of this and reports it on the unknown fields page.

How can you help?

Go to the unknown fields page (linked below). Look at the reported fields and compare them to the allowed template parameters (as given in the template documentation on Wikipedia). If you find the field in the documentation please get in touch with one of ErfgoedBot's maintainers to update the expected parameters for that country.

If you don't find the field in the documentation and it is only used infrequently then most likely one of the templates on the linked page has been malformatted. By going there and fixing it you will ensure that that monument is correctly harvested on the next day. If the field is very frequently used but not described in the documentation then raise the topic on the template discussion page. Either the template has been updated but the documentation hasn't or someone has systematically been changing the lists without understanding how the template works.

How can I localise the instructions?

Since the unknown field reports are overwritten by Erfgoedbot each time the list is updated you cannot add instructions (or categories) directly to the page. To solve this the /header sub-page is automatically included at the top of the page, if it exists. Thus to add instructions for volunteers in your own language simply create the /header sub-page with the required information.

To localise the message used when there are no more unknown fields, simply create a /done sub-page with the desired message.
