instantiationDuration provides a timestamp for the overall length or duration of a time-based media item. It represents the playback time.
Best practice is to use a timestamp format such as HH:MM:SS[:|;]FF or HH:MM:SS.mmm or S.mmm.
instantiationDuration can only be contained by pbcoreInstantiation.
Usage: Optional, not repeatable.
- source –required only for the elements pbcoreIdentifier and instantiationIdentifier; for all other elements, 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
instantiationDuration contains no subelements.
