Diagram of model structure

[skiwi]

Can anyone point me at a better model than this one attempting to show the structure of a UML model?

Arcs are elements too...   That's why I use Arcs and Vertices.

And...

They're composite not shared aggregations.  According to UML, the world is a tree not a lattice.

Hi skiwi,

I think you need to be careful to be clear about whether or not you are modelling UML or EA's implementation of UML.

In both cases, I believe the model is wrong... (But then isn't that the point of models - to spot problems early? - as mentioned in: Re: Multiple instance of same element in diagram)

Can you clarify which it is?  Then we can comment appropriately...

Thanks Paulo. This diagram is illustrating Sparx's implementation of UML in EA.

(Just as a background a colleague of mine has developed a document model to use as a generic template for producing printed documentation. Part of socialising this document model is providing a basic view and understanding of how a business/information/solution/... model (aka the diagram above) is rendered through the document model into an output document.)

In that case, Arcs are never mentioned in ANY EA documentation.  I use the term (with Vertex) so that I won't get confused with the names of other types of Arc (Link, Connector etc) which have specific meaning in UML (or EA).

I'd suggest Connector for Arc (since EA does have a t_connector table).

Also, I'd reinforce that Connectors have to connect Elements.

Finally, I'd add Text as a Diagram content.

HTH,
Paolo
