#Model Concepts in Dart#
Categories: design tool, graphical models, canvas, local storage, json.
##Description A graphical design tool for domain models of EDNetCore. Spirals can be found in the mb_spirals project. The last spiral is a graphical model designer. The json representation of a model is generated in Model Concepts. This representation is used in the EDNetCoreGen project to generate code for a model supported by the EDNetCore domain model framework.
If an attribute name is oid or code, it will not be generated as a specific attribute in EDNetCore, because every concept inherits both the oid (object id generated automatically by ednet_core) and code (an id that may be null, but if non-null it must be unique) properties.
In the attribute init field, you may use increment for incrementing a value of the int type in EDNetCore by increment starting with increment. The empty text indicates that a default value will be a non-null empty String. For the DateTime type, the now value determines the today's current time at the moment of adding an entity in EDNetCore.
