Dear all, I am helping the dev team on the DataONE project (dataone.org) understand and make the best of PROV-O in their production environment. One question that came up concerns versioning. Below are snippets from the recent conversation, for context. Question: how do you refer to a specific version of PROV-O? This can me a moot point as there may not be a next version but I hope you see the general point. Thanks for any insight Paolo >Išm thinking wešre going to have conflicts if we use the >http://www.w3.org/ns/prov# namespace to refer to different versions over >time.
