@bonfire Right – with OSN you're also thinking about academic creation, not only sharing? So letting authors declaratively cite specific sources in their posts could be good, as would searching/filtering for “what else cites this”.
Although tbh, my motivation for now is interop between Encyclia and OSN. I want Bonfire to recognize Encyclia posts as what they are (automated metadata summaries of specific academic works) and separate those from human discussions.
