EIDR, the Entertainment ID Registry has created a white paper on trailers for the registry. This document details the interim best practice for creating a Trailer Record as a Referent Type Supplemental with relationships to Theatrical Titles. More information about EIDR can be found at their website, http://eidr.org.
The EIDR organization is currently working on the Best Practices around Supplemental Content. In an attempt to provide guidance and best practices during the transition period the follow document outlines the procedure and best practices for registering a Supplemental Trailer record for Theatrical Content.
In general the creation of the Supplemental record for a Trailer is similar to that of any other root Level Object in EIDR. In this section we will identify the key best practices around the constriction of these records. To create a Supplemental Referent Type record, Trailer you need to construct the data in the following manner.
2.1 Structural & Referent Type
The Trailer should be considered a root level object, and should therefore be identified with the Structural Type of “Abstract”. In addition as a Trailer it should be identified as a Referent Type of “Supplemental”.
Structural Type: Abstraction
Referent Type: Supplemental
The title needs to refer the original work for which is it intended to be a trailer of in the Title. It is important that an identifying name is used to allow de‐duplication of these records.
