====Creating Utilisation Rules====

The utilisation system calculates the the [[state|state]] of each asset using **rules**.

Each rule must include a **method**.

<code>
{
            "method": "ValueMatch"
}
</code>

There are a few different //methods// - types of rule that each have their own specific parameters.

The most common is the [[ValueMatch]] rule, but there are others - and more will be introduced over time.

===List of Methods===

[[InEvent]] - Matches when the time for the sample is inside a specific event. \\
[[ValueMatch]] - Matches with the complete or partial text of a property. \\
[[NonZero]] - Chooses between options depending on if a value is 'zero'.
