Structural Fields

Structural fields provide how compound files such as collections are put together or how files are related between each other. Three categories exist: Fragments, Ensembles and Relations.

Record Tree

New since 21.2: ReferenceTitles

Key	Sub Key	Description	Remark
`ReferenceCodes`		Contains the full line of ancestors. More info Record Tree	`ComplexField`
`ReferenceCodes`	`Record`		`SimpleField`
`ReferenceTitles`		Contains the titles of the full line of ancestors.	`ComplexField`
`ReferenceTitles`	`Record`		`SimpleField`
`ParentRecordId`		If the record has a parent record, this value contains the `RecordId` of that parent.	`SimpleField`
`HasChildren`		If record has or had children in at least one point in time this will field be forever `true`	`BooleanField`

Fragments

Key	Sub Key	Description	Remark
`Fragments`		Series of fragments belonging to this file. The main fragment which corresponds to the file itself (i.e. the entire video) is non contained in this series, hence this list is empty if the file contains no pure (= non main) fragments.	`ListField`
`Fragments`	`Fragment`	Sub field of `Fragments` giving the `FragmentId` of each fragment this file contains	`FragmentId`
`MainFragment`		For a pure fragment, this refers the `FragmentId` of main fragment. For the main fragment this field is empty.	`SimpleField`
`FragmentStartFrames`		The start time of a fragment, relative to the start of the media file, expressed in frames against a fictitious 25 frames per second	frames (using a fictitious 25 fps)
`FragmentEndFrames`		The end time of a fragment, relative to the start of the media file, expressed in frames against a fictitious 25 frames per second	frames (using a fictitious 25 fps)

`FragmentStartTimeCode`		The start time of a fragment, relative to the start of the media file	`HH:mm:ss.SSS`
`FragmentEndTimeCode`		The end time of a fragment, relative to the start of the media file	`HH:mm:ss.SSS`
`FragmentDurationTimeCode`		The duration of a fragment	`HH:mm:ss.SSS`

Versioning

Key	Sub Key	Description	Remark
`Versioning`		Provides structural information about the chain versions of the same logical file. Each record in the chain is a separate record itself with its own MediaObjectId / FragmentId. All records in the chain have the same Versioning > Id.	`MapField`
`Versioning`	`Status`	Untracked for records without versioning, otherwise possible values are Draft, Head, Rejected, Tail.	`EnumField`
`Versioning`	`Id`	Has the same value for an entire versioning chain; its value is the MediaObjectId of the first record in the chain (with Version = 1).	`SimpleField`
`Versioning`	`Version`	Positional index in the chain of versions, starting from Version 1.	`LongField`

Ensembles

Key	Sub Key	Description	Remark
`Collections`		Series of collections the file belongs to	`ListField`
`Collections`	`Collection`	Sub field of `Collections` providing the ID of an individual the collection the file belongs to
`Sets`		Series of sets the file belongs to	`ListField`
`Sets`	`Set`	Sub field of `Sets` providing the ID of an individual set the file belongs to
`Newspapers`		Series of newspapers the file belongs to	`ListField`
`Newspapers`	`Newspaper`	Sub field of `Newspapers` providing the ID of an individual newspaper the file belongs to

Relations

Key	Sub Key	Description	Remark
`Relations`		Series of files related with this file. Depending on your installation different sub fields of `Relations` might be defined.	`MultiItemField`
`Relations`	`PreviousVersion`	Sub field of `Relations` providing the `FragmentId` of an individual file which is the previous version of this file	`FragmentId`
`Relations`	`NextVersion`	Sub field of `Relations` providing the `FragmentId` of an individual file which is the next version of this file	`FragmentId`
`Relations`	`Contains`	Sub field of `Relations` providing the `FragmentId` of an individual file which this file contains	`FragmentId`
`Relations`	`ContainedBy`	Sub field of `Relations` providing the `FragmentId` of an individual file that contains this file	`FragmentId`
`Relations`	`Associated`	Sub field of `Relations` providing the `FragmentId` of an individual file which is associated with this file	`FragmentId`

Rights Management Fields

...

`Relations`	`IsSuggestedFor`	Points to a record for which a suggestion is made	`FragmentId`
`Relations`	`HasAsSuggestion`	Points to a suggestion which is made for this record	`FragmentId`

Field Definition

New since 21.3

Key	Sub Key 1	Sub Key 2	Description	Remark
