- This service will apply to system dates and times: the dates and times of meaningful collections management events modeled by the CollectionSpace system, such as the date and time that an object was accessioned, loaned, exhibited, moved, or covered by conservation activities; dates and times related to an insurance contract or shipping manifest; or a date and time range during which temporary access permissions might be granted to a Principal.
- The This service will not attempt to represent dates and times, or named time periods, that might be encountered in the context of CollectionObject metadata or other forms of Annotations, such as "203 BC," "1962 CE," "European Renaissance," "Han Dynasty," or "Mesozoic Era."
If there is a need to support other types of dates and times, or named time periods, this should be carried out by a separate service or code base. For one possible starting place, please see Petras, Larson and Buckland's 2006 paper, Time period directories: a metadata infrastructure for placing events in temporal and geographic context
