I'm trying to find a word for the relation between a competition or an event and its offered sports.
Let's take the Olympic Games for example:
The event would be the Olympic Games. You can participate in different sports like boxing. A specific match would then be associated to a [insert word here] which identifies its event and sport.
In my case I have eSport competitions which offer different video games (here equal to sports) you can participate in.
Combinations are for example:
ESL One 2015 - DotA 2 ESL One 2015 - CS:GO ESL One 2015 - Hearthstone
How would you call these combinations?
