UML syntax: Typed elements

[ronaldtse]

Typed elements

• A typed element is a named element that can have a type.
  • Ex.- Attributes and parameteres.
• A type specifies a set of values for a typed element.
  • Ex.- Simple data types and classes are types.

Proposal:

class Booking {
  +booker: customer
}

# class MyClass {
#   +TypedElement: Type
# }

@ronaldtse looks good, but i would also add attribute notation:

class Booking {
  + attribute booker: customer
}

[ronaldtse]

As per #10 I think we need to allow a shorthand. The keyword "attribute" is fine, but allowing a shorthand of omitting it would be good.

Can you please explain the difference between typed element and derived attribute?

[ronaldtse]

"Typed element" is an attribute that accepts only a certain "Type".

Derived attribute is an attribute that has a value produced/assigned from another place: https://www.uml-diagrams.org/derived-property.html

They are prefixed with slash /myattribute. The following example is clear.
