Usage Notes

Purpose

Use of issued allows users to determine the currency of the described resource. It also helps the user to distinguish between the date the described resource was created, the date it was first made publicly available, and the date it was added to the Government Data Catalogue.

Do not confuse with

  • DATE ADDED TO CATALOGUE: the date on which the resource was included in the Government Data Catalogue.

  • METADATA RECORD CREATION DATE: the date on which a new Government Data Catalogue metadata record is created.

  • modified: the date on which the content of an information resource was changed, or when a new issue of a serial resource was added to the metadata record

Guidelines

The issued date should indicate the date on which the described resource was first published or otherwise released to the public.

Be as specific as possible, including month and day as well as year, if known.

If the resource was never publicly released before inclusion in the Government Data Catalogue, the DATE ISSUED and DATE ADDED TO CATALOGUE would be the same.

Some scenarios might be:

  • A dataset compiled in April 2015 published on July 2015 (issued is 2015-07);

  • A report completed in September 2015 but publicly released in January 2016 (issued is 2016-01);

TODOs

  • Refine guidance text inline with dates actually available in the metadata model
  • Add distinctFrom for all the different date types
