MIGX. Добавление полей к каждой статье в контейнер

Здравствуйте. Есть сайт журнала. Установлен MODX 2.2.7, Articles 1.6.0. Для каждого выпуска журнала создается контейнер в Articles, в который добавляются статьи. Хочу сделать базу авторов, которые будут добавляться в каждую статью журнала. Каждый автор должен иметь причастность к Университету (соответственно, должен быть готовый их список). Помимо этого для каждого автора должны быть поля Фамилия, Инициалы, Адрес почты, Университет, Идентификатор ORCID. Сейчас я попробовал реализовать это через midxdb так:

XML:

<?xml version="1.0" encoding="UTF-8"?>

<model package="authors" baseClass="xPDOObject" platform="mysql" defaultEngine="MyISAM" version="1.1">
    <object class="myAuthor" table="my_authors" extends="xPDOSimpleObject">

База данных создалась. Есть таблица, в котору я могу добавлять авторов. Я не знаю как реализовать добавление каждого отдельного автора из таблицы в конкретную статью из контейнера. При добавлении TV MIGXDB таблица появляется и в нее можно добавить новых авторов, но нельзя добавить их причастность к конкретной статье. Так же таблица вовсе не выводиться при «check_resid»:1.

Как быть в этой ситуации? Заранее благодарю.
