The module provides a service resource which exposes Drupal's entityform fields structure to the Service API. It provides formatted field information such as label, widget, options (select fields), and whether they are required or not.
This is necessary for mobiles apps and other ends to know the fields structure and their types before performing a CRUD.
It has an index resource which exposes a list of existing entityforms and a retrieve resource for filtering by single entityform type (not ID).
It also supports the TableField module.
