Date and Time Requirements

These requirements have informed the development of a prototype at SMK. It is used to generate date information based on the elements selected. This tool is based on an existing tool within their collections management system. The specification is described in the power point slides above.

1. Date entry in our current system generates Display strings in a predictable way.

...

Update 07 Sept 2010: A prototype has been created for this module, based on the specification included in the slides above.

Update 18 Nov 2010: Sample screen shots will be added to this page to demonstrate how the prototype works.

2. Date text is more detailed than the date ranges.

There is no explicit mapping to the SMK date format described in Kim's mapping spreadsheet. The decision has been taken to use the Date - earliest/single, Date - latest and Date text fields to represent all SMK date information (examples are shown below).
