Proposal: Captured qualifier for Date element

13 April 2002

This proposal is for review by Dublin Core community. It proposes a new element refinement Captured for the DC:Date element that is included in the proposed DC-Library Application Profile. This review period is 15 April-11 May 2002.



Proposal: Captured refinement (element Date)
Name captured
Label Captured
Definition Date that the resource was captured.
Comment Includes the date the resource was digitized or a subsequent snapshot was taken (particularly for dynamic resources) if different from Date.Created . Best practice is to use as a machine-processible date (ISO 8601 or W3CDTF).
Examples 1999
Type of term Element refinement
Term qualified Date
Why needed It may be necessary to distinguish the date captured from date created, particularly in cases where the intellectual content was created on a different date than that in which it was digitized or a subsequent snapshot was taken (particularly for dynamic resources).
Proposed status Domain-specific
Related DCMI terms Date.Creation: many library applications consider date created that of the intellectual content (this interpretation is specified in the DC-Lib application profile). It is important to also include the date of capture and to distinguish it as such.
Related non-DCMI terms  
Impact on applications Some applications may have used Date.Created for this because of the lack of a qualifier. This element refinement has been requested on several occasions. There is a known application (Colorado Digitization Project) that has used Date.Digitized locally for this concept.
