/**
- * The API entity classes are meant as data transfer objects. As such, their member should be protected.
- * Then the JsonSerializable interface ensures the protected members will be included in a JSON encode situation.
+ * The Entity classes directly inheriting from this abstract class are meant to represent a single business entity.
+ * Their properties may or may not correspond with the database fields of the table we use to represent it.
+ * Each model method must correspond to a business action being performed on this entity.
+ * Only these methods will be allowed to alter the model data.
+ *
+ * To persist such a model, the associated Repository must be instantiated and the "save" method must be called
+ * and passed the entity as a parameter.
+ *
+ * Ideally, the constructor should only be called in the associated Factory which will instantiate entities depending
+ * on the provided data.
*
- * Constructors are supposed to take as arguments the Friendica dependencies/model/collection/data it needs to
- * populate the class members.
+ * Since these objects aren't meant to be using any dependency, including logging, unit tests can and must be
+ * written for each and all of their methods
