DDMS 4.1: New abstract base class, AbstractApproximableDate, and concrete implementations.

Description

(Imported from Google Code)
This class represents the base type which allows an approximate date.

Class: buri.ddmsence.ddms.AbstractApproximableDate

Constraints:

  • Can have an optional "description" element (0-to-1, xs:string)

  • Can have an optional "approximableDate" element (0-to-1, CombinedDateType with optional "approximation" attribute)

  • Can have an optional "searchableDate" element (0-to-1) containing a "start" and "end" CombinedDateType

  • "approximation" attribute can hold values from the enumeration [1st qtr, 2nd qtr, 3rd qtr, 4th qtr, circa, early, mid, late]

Implementers:
buri.ddmsence.ddms.resource.Dates
buri.ddmsence.ddms.summary.TemporalCoverage

Complete in Rev 762.

The class ended up being a final class (ApproximableDate) rather than an abstract. In DDMS, every implementation of this type is a locally-defined element, so there was no need to have an abstract class underneath.
