We've talked in the past about how to show where a courser or finer resolution of the data can be found, and also were availability might be found. This is to suggest that in the info there would be:
x_time_finer:DataSetId
x_time_courser:DataSetId
x_availabilty: DataSetId
Chris at the U. Iowa group has shown that availability is not needed when a very course version of the data is available.
