Values are read from the space's latest non-invalidated definition nanopub. The date row shows the start and end dates; when both fall on the same day, it shows the day with the start and end times (and the timezone offset); when the end date is absent, only the start date is shown. The location row shows the location URI as a link and is omitted when no location is given. Both columns use the '_noheader' convention so the redundant header row is dropped.";
