# Resource Model API
Resource model is a [resource manifestation](http://www.w3.org/TR/di-gloss/#def-resource-manifestation).
One particular representation of your resource.

Furthermore, in API Blueprint, any `resource model` you have defined can be
referenced in a request or response section, saving you lots of time
maintaining your API blueprint. You simply define a resource model as any
payload (e.g. [request](https://github.com/apiaryio/api-blueprint/blob/master/examples/06.%20Requests.md)
or [response](https://github.com/apiaryio/api-blueprint/blob/master/examples/5.%20Responses.md))
and then reference it later where you would normally write a `request` or
`response`.
