ResourceName1The Series’ original release title in mixed case without trailing articles.

Conditionally Required[1]

Credits/Actor/DisplayName4The names(s) of the top billed actors (s) in natural name order (not “last, first”). Only include actors who appear in the vast majority of the Episodes.
Optional, But Recommended (if applicable)
AlternateResourceName128Additional names by which the Series 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 Series 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 Series record includes all of the material identified by the Alternate ID.
SeriesInfo/EndDate1Preferably the full date (yyyy-mm-dd) of the original commercial release of the final Episode. A 4-digit year (yyyy) is also valid. Include only if the Series has ended its run.
SeriesInfo/SeriesClass1Use “Mini-series” if the series was originally presented as a mini-series or “Anthology” if the series is primarily composed of episodes that stand on their own.
SeriesInfo/NumberRequired1“true” if child records must be identified by a unique number.
SeriesInfo/OriginalTitleRequired1“true” if child records must have user-supplied titles.


ApproximateLength can be 0. (Used when the child Episode records do not have a consistent duration.) Otherwise, a non-0 duration in the Series can be inherited by the child records.

Series records have NumberRequired, DateRequired, and OriginalTitleRequired Boolean elements (they can be “true” or “false”). If the element is missing, it is assumed to be false. These control the required fields in the direct child records. For example, if a Series has NumberRequired = “true”, then its Seasons must all have SequenceNumbers.

At least one of the Series-specific values must be present: EndDate, SeriesClass, NumberRequired, DateRequired, or OriginalTitleRequired.
