Yes, the quality of persistence is why I thought rel=bookmark worked best, although canonical was the relation I first thought of too. As the IETF draft authors describe in a related blog post [1] canonical was dropped from consideration because it exists to "identify content that is either duplicative or a superset of the content at the context (referring) IRI" and does not speak to the durability of the link. //Ed [1] http://ws-dl.blogspot.com/2016/11/2016-11-07-linking-to-persistent.html
