From Jim:

"Right now, if you include

Preferences: {
“Purpose”: “Testing-Only”,
…
}

With
@context {
"Purpose":http://sead-data.net/vocab/publishing#Purpose
}

the management console will display a “Delete This Request” button to help with cleanup of old/failed requests. I’ve just pinged Isuru to see if we can also implement that flag in the cron job, and then to allow cleanup in sda/other repositories (if we mint test DOIs, they stop working in 2 weeks, so we probably should be deleting the data on that timescale too with another cron process… I’m starting to do that with the bob implementation.).

I’m open to other labels/predicates if you think it should be different – just have to coordinate deployment if we change."
