Data Fields – Digital Manifestation

Technical Manifestations include specific details describing the internal components and structure of the Manifestation. This can be quite extensive and is all contained inside a Digital element:

<xs:element name=”Digital” type=”eidr:digitalTracksType”/>

A Digital element may contain any number of the following in any order:

Field NameTypeCardinalityExplanatory Notes
Track<xs:element name=”Track” type=”md:DigitalAssetMetadata-type”/>0-∞ OptionalLogical tracks of the Digital Manifestation.   Track is a complex type where all data are recorded in child elements   See “Digital Manifestation Tracks” below.
Container<xs:element name=”Container” type=”md:ContainerMetadata-type”/>0-∞ OptionalContainers of the Digital Manifestation.   Container is a complex type where all data are recorded in child elements   See “Digital Manifestation Containers” below.

Here is sample XML for the Extra Object Metadata for a technical Manifestation with Digital details (the preceding Base Object Data is not shown):
