Sub-space membership is read from the validated current space state. The descriptive triples come from each sub-space's current defining nanopublication: among the valid (not invalidated, not superseded) nanopublications introducing the sub-space, the most recently created one wins, so an override published by another admin under a different signing key replaces the earlier definition instead of adding a second row. Reads both the http:// and https:// schema.org namespaces. The website column links to the event's schema:url (http or https form) when it has one, labelled with the bare host and path; it is empty otherwise.";
