The "Related Modules" form a list of all of the modules within the "topic cluster" to which that module belongs. All modules must belong to a topic cluster. Current Topic Clusters, tcref names, and descriptions of each are provided in the DKN module: DAISY Knowledge Network Topic Clusters. Please refer to this when creating a module.
Indicate in the metadata to which Topic Cluster the module being submitted belongs. In the metadata, use the tcref name (in parentheses beside the Topic Cluster name). If the module does not 'fit' into any of these categories, please provide the name for a new category/Topic Cluster in the metadata and indicate when the module is submitted that a new Topic Cluster needs to be added to the DKN.
