Required Data Fields – Abstraction


These are root records with a ReferentType of Movie, Short, TV, Web, or Supplemental, sometimes called “title” records. The StructuralType is always “Abstraction”. For “title” Abstraction records that are episodes of a series, see the Series section, below.

Element NameMaximum CardinalityData Requirements

Conditionally Required[1]
AssociatedOrg16The companies associated with the Abstract, preferably the production companies.
AssociatedOrg/DisplayName1Required only if an organizationID is not provided.
[email protected]1“EIDRPartyID” Required only if an Organization ID is provided.
[email protected]1The EIDR Party ID of the Associated Org. Required only if a DisplayName is not provided.
[email protected]1Most often “producer”.
Credits/Director/DisplayName2The names(s) of the director(s) in natural name order (not “last, first”)
Credits/Actor/DisplayName4The names(s) of the top billed actors(s) in natural name order (not “last, first”)
Optional, But Recommended
AlternateResourceName128Additional names by which the work is also known. Include as many as possible.
[email protected]1Same as for Resource Name.
[email protected]1Same as for Resource Name.
AlternateIDIDs associated with the Abstraction other than the EIDR ID (IMDb, ISAN, house IDs, etc.). Include as many as possible.
[email protected]1Common IDs have their own type (“IMDB” for IMDb IDs, etc.). Others use the type “Proprietary” with an identifying domain.
[email protected]1Identifies the organization that issued the Alternate ID. Required when type is “Proprietary”.
[email protected]1“IsSameAs” (in most cases) If not present, “IsSameAs” is assumed. The relation value describes how the EIDR ID relates to the Alternate ID. For example, “ContainsAllOf” would indicate that the EIDR Abstraction record includes all of the material identified by the Alternate ID.


The Required elements are always required for every record. In root Abstraction records, they must be provided directly.

The Optional elements are always optional (but always encouraged) – the more descriptive metadata provided, the more accurate the de-duplication process is – both for the initial registration and in the future when others match or try to register the same thing, perhaps as a foreign release in a different territory. We both encourage registrants to provide the optional data and to fill in multiple values when they are available and allowed.

The Conditionally Required elements follow the rule that at least one of the following Participant data values must be provided (more are welcome, but each record must meet at least one):

  • An Associated Org (preferably, a producer)


  • A Director


  • 4 Actors

Finally, some attributes are required when their XML tag is present, and others are optional. The optional attributes are marked with italics.
