7.3. Document Type Model | 7.3.7. Configuring Translation Support

If you work with content in multiple languages and want to derive translated documents from source documents in a primary language, you can support the editors by providing a side-by-side view of both documents. To this end, a resolution strategy for matching translated documents can be configured.

A source language document resolver is simply a function that takes a Content object as its single argument and returns the Content from which the given content was derived. If no source document is available, the resolver returns null. So that the document forms for the translated document and the source document can be properly aligned in the side-by-side view, the returned content must belong to the same content type as the argument content. In the document model of CoreMedia Blueprint, the resolver function can simply follow the link list master to determine a source document.

public function resolveMasterDocument(content:Content):Content {
  var contentProperties:ContentProperties = content.getProperties();
  if (contentProperties) {
    var readOnlyContents:Array =
      contentProperties.get('master') as Array;
    if (readOnlyContents) {
      return readOnlyContents[0] as Content;
    }
  }
  return null;
}

To configure a source language document resolver, the configureDocumentTypes Studio plugin can be used. A resolver is used for the given content type and all subtypes. If multiple resolvers are available, the resolver for the more specific content type takes precedence.
