OpenReview has a nice lightweight model for submitting posters and papers to conferences, and generating an online proceedings with public reviews.
PubPub has become quite good at generating a quick site for a conference, including papers with public comments and other document-centered discussions.
Can we combine the two approaches? Or integrate directly? There’s an implicit templated workflow for each sort of event, and OR is strongly designed around something that is only one of many options in a pub community. But perhaps community creators could more actively choose workflow norms, and publication/creation forms, just as they choose navigation and visual layout.
