Key Date (autogenerated)
Abstract
Autogenerated
MODS Element name: <originInfo><dateCreated keyDate="yes"> (Creation date) or <originInfo><dateIssued keyDate="yes"> (Issuance date)
Short definition: System-generated, machine-readable date value derived from either Creation Date or Issuance Date.
Input guidelines: The system will create a machine-readable date element with a keyDate attribute based on the user-provided information for Date created or Date issued. If a date range is specified, only the start date will be used as key date. If textual date information is provided, the key date will be a numerical date approximating the textual date information. The machine-readable date is for instance used for sorting of search results.
The ingest process currently ignores a keyDate attribute set by users when preparing metadata as MODS XML. Instead, the system will create a new machine-readable date element with a keyDate attribute based on dateIssued or dateCreated (in this order and depending on which of the two is available). Any user-provided keyDate attribute will be stripped from the metadata upon ingest.
If you want to designate a specific date element as the key date in metadata prepared for batch ingest, add the following attribute-value pair to the respective element: keyGen="yes".
Definition

DAMS input form fields
System-generated metadata element. These elements cannot be edited in the DAMS metadata web form.
MODS Element description
Element <originInfo>
http://www.loc.gov/standards/mods/userguide/origininfo.html
Guidelines for use
<originInfo> is a container element that contains all subelements related to publication and origination information. It includes all dates associated with the creation, issuance, and/or publication of the resource. Dates associated with the temporal content of the resource go under <subject>, and dates associated with the metadata go in <recordInfo>. Data is input only within each subelement.
Attributes
Currently no attributes for originInfo are implemented in the DAMS.
Subelements
The following subelements of <originInfo> are used in the DAMS:
dateCreated
dateIssued
(copyrightDate)
(place)
(publisher)
Subelement <originInfo><dateCreated>
