http://purl.org/dc/terms/description
Renders the schedule of an event as one SVG per day: a grid with one column per room used that day, boxes placed at their real clock positions. Covers both the presentations that are part of the event and its workshop, tutorial and session sub-spaces, which are coloured differently and link to their own space pages. The per-slot ranking joins two separately computed sub-selects rather than filtering a cross product, which the engine evaluated as a nested loop. Box text adapts to box height: an author line and two title lines where they fit, otherwise a single centred title line with the full title and authors as a hover tooltip, and no text in boxes too short for one line. Reads both the http:// and https:// schema.org namespaces. Where several valid nanopublications introduce the same talk or sub-space (e.g. an override published by another admin, which carries no supersedes link), only the most recently created one is used, so an item is never counted twice. Each box links with an explicit &context= naming the event, so that a talk opened from the schedule lands with the conference as its navigation context; without it Nanodash appends the context of the page the schedule happens to be rendered on, and from the schedule's own resource page that is the schedule, on which the part page renders none of its views.
