Comparison

Overview

  • According to the project page for Entity Reference Revision module:

    Entity Reference Revisions adds an Entity Reference field type with revision support, allowing specific entity revisions to be references. This is useful for modules like Paragraphs and Inline Entity Form

  • According to the project page for Dynamic Entity Reference module:

    Dynamic Entity Reference provides a field type/widget/formatter combination for Drupal 8 that allows an entity-reference field to reference more than one entity type.

  • According to one of the blog post:

    Entity Reference and Entity Reference Revisions fields are very similar, both enables more flexiblae reuse of data across the website, but the latter offers more flexibility when it comes to reverting to a previous revision in the case when you have a nested entity. In other words, this field type allows you to reference a specific entity revision.
