instantiationStandard: If the instantiation is a physical item, instantiationStandard can be used to refer to the broadcast standard of the video signal (e.g. NTSC, PAL), or the audio encoding (e.g. Dolby A, vertical cut). If the instantiation is a digital item, instantiationStandard should be used to express the container format of the digital file (e.g. MXF).

Best practice: While the usage described in the definition is best practice for 2.1, this usage is likely to change if new elements are added for PBCore 3.0.

instantiationStandard can be contained by the elements pbcoreInstantiation, pbcoreInstantiationDocument, and instantiationPart.

Usage: optional, not repeatable.

Attributes

• profile – optional. The profile attribute is used to further quantify the profile of the container format (e.g. Op1a). Can be used as a notes field to include any additional information about the element or associated attributes.
• source – optional. The source attribute 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. The ref attribute is used 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. The version attribute identifies any version information about the authority or convention used to express data of this element.
• annotation – optional. The annotation attribute includes narrative information intended to clarify the nature of data used in the element.
