"Lists the sub-spaces of a given conference Space, one row each, each linked to its own page, with whether it is a Workshop or a Tutorial (conference-ontology), and its day, time and room, ordered by when it starts. Sub-space membership is read from the validated current space state; the descriptive triples come from each sub-space's current defining nanopublication, with superseded and invalidated versions filtered out.
