Hello,

what is the difference between UML Attributes and SYSML Properties?

According to the author of SysML Distilled, UML Attributes are DataTypes (e.g., Strings) whereas SYSML properties are ValueTypes (e.g., can be assigned computed values).

Can anyone elaborate on this?

Cheers,

Philippe

Hi,
Attribute or Properties in SysML are instances of the metaclass Propery.

A property in SysML and UML are TypedElement.
So you can type your attribute or property by a primitive type as a String an integer... or by a Class, a Datatype, an Interface...

In the context of SysML, there is specialization. There are the concepts of parts and in references. There are properties that must be typed by Blocks. Morever when you create these elements, assocations have to be created.
