The structure of Medium Events is fixed, with two data types: Program Items and Persons.
In Program Items, you can add items that relate to the daily program. These can be either sessions or presentations within sessions, and they must be nested inside a day.
In Persons, you can add persons related to the event. Persons can be linked to the programme as Chair (in sessions) or Speaker (in sessions or presentations).
Renaming the data types
To customise your app, the default names of the data types can be edited. This is done in the Pages & Structure page, Data Structures tab.
