User stories:

As a contributor who has not yet joined the event, I want to see the topic(s) of the event when I discover the event on the Collaboration List or when I read up on the event in other places (such as EventDetails), so I can know if the event focuses on a topic that interests me, so I can determine if I want to participate in the event based on my skills and interests.

As an organizer, I should be able to add the topic(s) of an event when I configure Event Registration, so that people can find my event when filtering by wiki in the Collaboration List and so that the movement can begin collecting data on campaign contributions per topic for events.

As an organizer, I want to be able to see the topics of events organized by others, so that I can know who is organizing around topics that interest me and then potentially contact them to share skills and/or to look at their work as inspiration.

As a participant, I want to be able to see the topic(s) of the event when I view the EventDetails page or discover the event in other places, so I understand on which topic(s) the event will be have an impact on.

As a product or data analyst at the Wikimedia Foundation, I want to know the topic(s) of an event that uses Event Registration so that I can more easily generate data related to contributions via events per topic.

Background:

We are currently able to collect data related to organizers and participants of events via Event Registration, but we do not yet collect data on the topic(s) of events. This only gives a partial picture of the event and its impact. We would like to expand the data we collect to include the topic(s) of the event, so we can improve a few things:

• Usability of the Collaboration List: Right now, a user of the Collaboration List cannot easily find events based on topics. This creates a real challenge, since many contributors choose to join events because of the event topic. For this reason, users should be able to easily filter the list to only the events that focus on topics that interest them. This way, they can find events that they want to learn more about or join with greater ease.
• Analytics related to event impact: If we know the topical focus areas of events, we could potentially help provide insights on where/how people are organizing and creating content collaboratively per topic on the wikis.
• Potential future project: worklists: If we want to do a worklist project in the future, it would be helpful to know the topic(s) of the event. This way, organizers and contributors can easily find older worklists for inspiration or to continue the work.
• Potential future project: event notifications: If we want to do a project in the future that would allow people to be notified about new events that may interest them (such as: events on gender for Spanish Wikipedia, events on climate activism for French Wikipedia), then we would need to collect the topic of the event.

Rules & limitations:

• We will allow organizers to pick a maximum of 5 topics per event
• We will allow organizers to modify or change the topics of event at any time (before, during, after the event)
• We have the search filters function with 'or' rather than 'and' statements for the MVP in the Collaboration List
