DateStructure package

The package allows to store a complex date structure in template fields. The package includes the following pages:

• Form:Date - a partial form to be transcluded into other forms
• Template:Date - a template that renders a single date item
• Template:DateFormatDate - a template that formats a date

The Date partial form includes the following fields:

• Present - The flag idicates the date is present date
• Date - The date, can be a partial date like Year only, or month & year only
• Circa - Boolean to indicate that date may be fuzzy
• Concurrence - Can be set to: Exact, Before, After
• Questionable - Can be checked to mark the date as questionable

Demo pages

The package also includes sample SampleDateTemplate and SampleDateForm as a usage examples. You can import the package and navigate to SampleDate1 to test it right away.

Usage examples

The form is to be transcluded into other forms directly via {{Form:Date}} like below:

...
{{{for template|MyTemplate}}}
{|
| Creation date
| {{Form:Date|Prefix=Creation}}
|-
| Publication date
| {{Form:Date|Prefix=Publication}}
|-
|}
{{{end template}}}
...

And in the resulting MyTemplate the fields need to be processed via Date template like below:

; Creation date
: {{Date
  |Creation
  |Present={{{Creation Present|}}}
  |Date={{{Creation Date|}}}
  |Circa={{{Creation Circa|}}}
  |Concurrence={{{Creation Concurrence}}}
  |Questionable={{{Creation Questionable}}}
  |EndPresent={{{Creation Present End|}}}
  |EndDate={{{Creation Date End|}}}
  |EndCirca={{{Creation Circa End|}}}
  |EndConcurrence={{{Creation Concurrence End|}}}
  |EndQuestionable={{{Creation Questionable End|}}}
}}
; Publication date
: {{Date
  |Publication
  |Present={{{Publication Present|}}}
  |Date={{{Publication Date|}}}
  |Circa={{{Publication Circa|}}}
  |Concurrence={{{Publication Concurrence}}}
  |Questionable={{{Publication Questionable}}}
  |EndPresent={{{Publication Present End|}}}
  |EndDate={{{Publication Date End|}}}
  |EndCirca={{{Publication Circa End|}}}
  |EndConcurrence={{{Publication Concurrence End|}}}
  |EndQuestionable={{{Publication Questionable End|}}}
}}

Each date has optional end date value, this is controlled by the Has end date? checkbox. When ticket it will reveal a set of fields for the end date to be entered. The fieldset is similar for the start date.

If the end date is set on the form the resulting template will render two dates in the following format:

date1(non-breaking space)(dash)(space)date2

the template will also pass this data to the subobject as the following properties:

• Present
• Date
• Circa
• Concurrence
• Questionable
• EndDate
• EndDateCirca
• EndDateConcurrence
• EndDateQuestionable

please note: that in all cases both start and end date fields are filled with values, even if the date has no Has end date? checkbox ticked the End prefixed properties will receive a values from the original date, in other words if no end date is added the end date matched the start date

The Form:Date wraps the date inputs into the following markup:

• div.dates-input-block - wraps the whole set if inputs for a single field
• div.dates-input-block--date - wraps a single date input (either start or end date)
• div.dates-input-block--start - wraps start date block only
• div.dates-input-block--end - wraps end date block only
