# State tree
#### Can I store additional metadata for resources within `meta`?
You can, and we encourage it. We recommend that you avoid changing the values of
the request statuses directly (use the built-in Action types to do this), but
feel free to store anything else in there that you want.
You can use the `UPDATE_RESOURCES` action type to change the metadata of
resources.
If you'd like to update metadata alongside a request, then you can write a
[plugin](../other-guides/custom-action-types.md) for that.
A future version of Redux Resource will support this without a plugin.
#### Can I store additional properties on each state slice?
Yes, you can. The only requirement is that you don't change the structure of the
state that you start out with: make sure that `resources`, `meta`, `lists`, and
`requests` remain Objects. If you stick with that you shouldn't run into any issues.
As a convention, we recommend only storing data relevant to the resource in the
slice. Use another slice for other information.
#### Can I store more than one resource per state slice?
We don't recommend doing this.
