Tags added to an Item definition allow a user to characterize the specific nature of the Item beyond its basic Item type.
Tags can then be used by add-ons to interact with Items in context-sensitive ways.
Tags are used by the [Semantic Model]({{base}}/tutorial/model.html). The `"Light"` example below maps the item to the Semantic Model.
Example:
A Light in a typical home setup can be represented by a Switch, a Dimmer or a Color Item.
To be able to interact with the light device via a natural voice command, for example, the fact that the Item is a light can be established by adding the "Lighting" tag as shown below.
```java
Switch Livingroom_Light "Livingroom Ceiling Light" ["Lighting"]
Switch Livingroom_Light "Livingroom Ceiling Light" ["Light"]
```
Tagging is a new feature and only a few I/O add-ons have implemented it.
The easiest way to determine if tags have been implemented in a specific add-on is to see if the add-on documentation explicitly discusses their usage.
Tags will be ignored if no Items in the openHAB installation support it.
See the [Hue Emulation Service](/addons/integrations/hueemulation/) or [HomeKit Add-on](/addons/integrations/homekit/) documentation for more details.
