Gaphor uses the UML and SysML Specifications as guidelines for its own datastorage. The Python data model is generated from a Gaphor model file thatdescribes the relationships between the supported UML elements.

The model is built using smart properties (descriptors). These propertiesemit events when they’re changed. This allows the rest of the application,for example, the visuals and undo system, to update their state accordingly.The events are sent using a signaling mechanism, called handlers.

A UML diagram is a diagram based on the UML (Unified Modeling Language) with the purpose of visually representing a system along with its main actors, roles, actions, artifacts or classes, in order to better understand, alter, maintain, or document information about the system. UML is an acronym that stands for Unified Modeling Language. Simply put, UML is a modern approach to.

• Unified Modeling Language (UML) is a language of graphic description for object modeling in the field of software engineering. UML was created for definition, visualization, designing of software systems. UML is an open standard that uses graphic notations for creating visual models of object-oriented software systems. Two types of diagrams are used in UML: Structure Diagrams and Behavior.

Pay attention to the following changes/additions with respect to theofficial Gaphor model, in the models/UML.gaphor file:

• Additions to the model have been put in the packageAuxiliaryConstructs.Presentations and .Stereotypes.

• A Diagram element is added in order to model the diagrams.

• A special construct has been put into place in order to applystereotypes to model elements. The current UML Specification is notclear on that subject.

• The Slot.value reference is singular.

• ValueSpecification is generated as if it were a normal attribute. As aresult, its subclasses (Expression, OpaqueExpression, InstanceValue,LiteralSpecification and its Literal* subclasses) are not available.
