At yesterday’s COSIMA meeting we lamented how it’s impossible to know whether output is still actively used, which makes it hard to know what can be archived to tape. It would be helpful to have file usage tracked via the cookbook, as suggested [here](https://github.com/COSIMA/cosima-cookbook/issues/231). Is that something ACCESS-NRI could help with?

Yes.

We aspire to track usage of ACCESS-NRI products (for want of a better word), for reasons as you allude to above, but also for “justifying our existence” reasons.

We aim for the same infrastructure to be usable for COSIMA Cookbook, even for datasets that were not support by ACCESS-NRI as a service to the community.
