Recommended Additions

hasCreationDate (make it a subproperty of hasStartDate)

For reports, contracts, and many other things.

asOfDate a subproperty of hasDate

Used for credit reports.  Not necessarily the same as creation date, which could be later. Similar to but not quite the same as effectiveDate
ALSO: ctr:effectiveDate should probably be a subproperty of asOfDate, since it means effective "as of" a given date.

datatype property for version indicator
