Complex type information

Content

• gml:TimeCalendarEra [0..1]    gml:TimeCalendarEra inherits basic properties from gml:DefinitionType and has the following additional properties: - gml:referenceEvent is the name or description of a mythical or historic event which fixes the position of the base scale of the calendar era. This is given as text or using a link to description held elsewhere. - gml:referenceDate specifies the date of the referenceEvent expressed as a date in the given calendar. In most calendars, this date is the origin (i.e., the first day) of the scale, but this is not always true. - gml:julianReference specifies the Julian date that corresponds to the reference date. The Julian day number is an integer value; the Julian date is a decimal value that allows greater resolution. Transforming calendar dates to and from Julian dates provides a relatively simple basis for transforming dates from one calendar to another. - gml:epochOfUse is the period for which the calendar era was used as a basis for dating.
