I maintain list of African heads of state and African governmental ministers, so this is just a next list to prepare. The workflow is as follows: I create an item for a position, on the talk page I add a template that contains the data and pointers to what is missing. Typically such information can be found on a Wikipedia list, this time I have to rely on templates on Wikipedia articles.. All my lists are "works in progress" and are on my watch list.
I have added copies of the Listeria lists to many Wikipedias. The texts are in English, the data is shown in the local language. It being in English is a reason to refuse these lists in several communities.
The Listeria functionality is replaced by Wikimedia Foundation maintained software. All the list definitions and expressions exist in one place. The data is shown in a language that can be selected. When a list changes, it is reflected on watch lists. You can watch for all data and possibly for data and labels in "your" language. A project can opt in to enable the use of these lists when they don't, functionality is available to compare a list with the centrally maintained list.
Thanks, GerardM
