Hello John Joyce,
Thanks for the reply, i am trying to understand what is the deprecation process means in Datahub, From the Slack i came to know that if any dataset is not in use in current state, instead of deleting from the Datahub, it is still exist in UI and in backend, but in UI it will be tagged as Deprecated, so in that case if any lineage/stats/tags associated for that dataset also will be deprecated.
