. . . . "Returns all presentations of the given event, with label, date and time, location, and the people involved - the presenter first where known, then the authors - plus the nanopub link, in chronological order. Reads both the http:// and https:// schema.org namespaces. Authors who are also listed as presenter of the same presentation are excluded from the authors part of the people column by a per-presentation not-exists check, so a person never appears twice. Date and time share one column as plain text (\"2026-09-17 14:00–15:00\"): a bare date is rendered by Nanodash as a relative time from midnight UTC, which showed a talk later today as hours ago." . . .
