Background & problem:

This ticket relates to T385342 and T434017. By working closely with campaigns on Wikimedia Commons, we noticed that it might be a bit confusing for some community members the usage of the “Event” namespace when the situation is not solely an “event". As an organizer, it would make sense to have the option to choose between “Event” and "Campaign”.

Later, when T385342 and T434017 are addressed, both “Event” and “Campaign” could be added to the aggregation space (name to be decided), that being by an affiliate, global campaign, etc.

Note: we use the word “campaign” for several instances in the projects. It might be important to differentiate between a local campaign (Wiki Loves Monuments 2026 Uruguay), a global-year campaign (Wiki Loves Monuments 2026 / Wikimedistas de Uruguay 2026), and a multiple-year campaign (Wiki Loves Monuments / Wikimedistas de Uruguay).

Proposed change:

Add the option in Event Registration for “Campaign”. This could be added to the EnableEventRegistration page as an option/field and as a feature to be enabled for pages created under the namespace “Campaign”.

Note: on Wikimedia Commons, the namespace “Campaign” exists and it's used in some instances (examples here and here). These pages could be used to track campaign registration, in addition to media uploads via Event Registration (T435574), as they are already used by campaigns to organize their uploads.

Use cases:

This would be really useful on Wikimedia Commons, due to Wiki Loves campaigns, but it would also make sense on Wikipedia (considering the different campaigns run by communities on the project) and on Meta-Wiki.

On Meta Wiki, we have several examples, such as the Celebrate Women campaign, which is using the “Event” namespace, but it's rather a global campaign, and it encompasses a lot of other individual events and campaigns.

Benefits:

Campaigns would use Event Registration to have registrations and access to the other CampaignEvents features, but also be recognized as a “campaign" and not solely as an event. This would allow them to be understood by participants as a place that represents a long-term engagement or an aggregation of local/smaller events.
