Different Events have different ways of structuring the matches to find a winner. Draws allow you to describe those structures.

1. What is a Draw?

An event is usually made up of a group of matches and when all the matches have been played someone is declared the winner. Different events have different structures for how those matches are arranged to determine the winner. In TODS these structures are called Draws and an event can have any number of draws.

2. Draw Structure

TODS has three types of Draw Structures. Using these types as building blocks you can create all the different formats used in tennis events.

Round Robin

A group of players (or pairs or teams) all play each other one or more times. At the end of the Draw players can be ranked based on number of matches won or similar criteria.


Matches are arranged into a series of rounds. Winners of the matches in each round progress to the next round. Losers may be out or may progress to a different draw (for example in Compass). This type of draw is also known as a bracket.


Matches have no specific structure or progression - often used for play-offs.

3. Creating a Draw

The mandatory information required to create a Draw entity is DrawId and DrawStructure. Providing a name is strongly recommended. Where are name is not supplied clients should use the draw type to create a name.

  "Draw": {
    "DrawID": "Tennis:Draw:DrawID:Draw1",
    "Updated": "2019-12-01T01:01:01+00:00",
    "IDs": { "ID": "Tennis:Tournament:TournamentId:349C4B46-9EB6-4E52-9486-38C02911FF03:Event:EventId:Event1:Draw:DrawID:Draw1" },
    "Name": "Draw1",
    "DrawStructure" : "KNOCK-OUT"

4. DrawID

In DrawID you must supply your unique identifier for the Draw. The value must be unique within the tournament. You can use any value but a unique identifier can easily be created by concatenating the EventId with information about the draw.

When you’re exchanging information with a client or supplier it is possible that you both have an ID for the Draw. To make exchange easier TODS allows for any number of additional IDs to be included with Draw. See ‘Including Multiple Identifiers’ for more information.

5. Matches and Ties

A Draw is usually made up of a number of matches arranged based on the DrawStructure. But in the case of an event between teams (e.g. France vs Sweden) the Draw will contain a set of Ties. Other elements remain the same.
