pbcoreAssetDate

pbcoreAssetDate is intended to reflect dates associated with the Intellectual Content.

Best practice:  By contrast, instantiationDate is intended to reflect date information for the specific instance. For instance, if you have a VHS copy of Gone With The Wind, the pbcoreAssetDate would be 1939, while the instantiationDate of the VHS copy could be 1985. pbcoreAssetDate may also be used to reflect availability dates, etc. Date types should be specified using the @dateType attribute.  Dates or time-based events related to the content of the asset, on the other hand, would be described in the ‘coverage’ element — so, while the storyline of Gone with the Wind takes place in the nineteenth century, this information should be noted in the Coverage field, not the assetDate field.  Best practice is to use ISO 8601 or some other date/time standard if possible.

pbcoreAssetDate can be contained within the elements pbcoreDescriptionDocument or pbcorePart.

Usage: optional, repeatable.

Attributes

  • dateType – optionalAttribute dateType classifies by named type the date-related data of the element e.g., created, broadcast, dateAvailableStart. Used to clarify how the assetDate is related to the asset. Date Created may be the most common, but the element could also be used to describe the Date Accessioned or Date Deaccessioned, for example.
  • source – optional. Attribute source provides the name of the authority used to declare the value of the element. Different elements will use the source attribute slightly differently.  For example, identifier source (required) should be the name of the organization, institution, system or namespace that the identifier came from, such as “PBS NOLA Code” or an institutional database identifier.  For other elements, this might be the name of a controlled vocabulary, namespace or authority list, such as Library of Congress Subject Headings.  We recommend a consistent and human readable use.
  • ref – optional. Use attribute ref to supply a source’s URI for the value of the element. Attribute ref can be used to point to a term in a controlled vocabulary, or a URI associated with a source.
  • version – optional. Attribute version identifies any version information about the authority or convention used to express data of this element.
  • annotation optional. Attribute annotation includes narrative information intended to clarify the nature of data used in the element. Can be used as a notes field to include any additional information about the element or associated attributes
