 The goal of the following [Cron Workflows](https://argo-workflows.readthedocs.io/en/stable/cron-workflows/) is to check the validity of the STAC metadata published in the AWS Open Data Registries [NZ Elevation](https://registry.opendata.aws/nz-elevation/) and [NZ Imagery](https://registry.opendata.aws/nz-imagery/).
 
-> **_NOTE:_** To simplify the overall workflow deployment process, these `CronWorkflow` have one main task per registry. It looks like a duplication that could be avoid but as we are not using [`argo` CLI](https://argo-workflows.readthedocs.io/en/stable/walk-through/argo-cli/) to deploy the workflows - which allows parameter passing - we could not deploy one `CronWorkflow` per `uri` (or registry).
