Attributes or TaggedValues

[rupertkiwi]

Hi,

I am creating a model in EA and I have a bunch of elements that I want to store values for.

Is it better to store the values in TaggedValues or in the default value of an Attribute?

Thanks,
Rupert

It depends.
If you end up adding the same attributes to all elements of a certain category, than you should use tagged values.
(e.g. owner, costprice, etc....)

Attributes typically are different for each element

The term Tagged Value should be banned. They are stereotype properties.

Well some stereotype properties are "more equal than others", as we've discovered.

But your point is well made.  Some tagged values end up as item properties and others as simple tagged values.

It's true, the term tagged values as it applied to stereotype properties is largely historic. These days EA shows the stereotype properties as equivalent to metaclass properties.

EA still allows non-stereotype tags, but if it makes you feel better think of those as a property of a stereotype EAElement which is applied to everything automatically. It has a property tags with 0..* entries containing name, value and note.
