Note: There are cases where a tournament doesn’t fit the usual definition but can still be represented by a Tournament entity in TODS. Some examples:

• A tennis ladder at a club - this could take place over a whole season.
• Davis Cup World Group (to 2018) - matches take place all over the world

TODS defines a set of standard attributes that are widely used within tennis. If you need to supply some extra information that doesn’t fit one of the standard attributes you can use an extension. See ‘How to included additional information using extensions’ for more information.
