 an entity for the definition of attributes

+The Attribute entity is for creating new attributes that can be used in different other entitys. Attributes are stored in the database table "AB_ATTRIBUTE".
+
+== Data Structure
+
+An Attribute can have a parent attribute, the id of it is saved in the field "ATTRIBUTE_PARENT_ID". With that, attributes can be structured in groups and
+there is no limit to the depth of the tree-structure.
+
+== Difference to "AttributeRelation_entity"
+
+Don't confuse this entity with the "AttributeRelation_entity". The Attribute_entity defines the attributes that can be used in the AttributeRelation_entity,
+while an AttributeRelation represents the value set for one attribute and dataset.
+
+== Attribute types
+
+There are different types of attributes that can hold different kinds of values, like text, dates or numbers. Besides these also exist special types like groups, selections or
+object selections. These types are defined by the keyword "AttributeType". Behind every keyword entry of that keyword lies an entry in the object "$AttributeTypes" in the Attribute_lib,
+where properties such as the content type, the database field to store the value or other special properties are defined. In that library there also are functions to get these properties
+in AttributeTypeUtil. This logic makes it possible to handle attributes in the code in a generic way. Because of this, new attribute types could be added without
+too much effort.
