Missing Column Metaclass?

[TonyC]

In my MDG Technology I wish to add a stereotype that extends the Column Metaclass... except there isn't a Column Metaclass to pick.

I have tried extending the Attribute Metaclass in the hope that Column was itself an extension of Attribute, but to no avail.

The Column properties window is quite different in look, feel, and function to the other Properties windows such as Class and Attribute and Table. Is this because Column is not a UML element type?

Any way around this? Ideas welcome.

Thanks,

Tony

Hi Tony,
all the other DB related vertices and EAUML::<something>.  i don't think you are extending a metaclass.  You're extending a stereotype.

HTH,

Hi Paolo,

Thanks, I can see what you mean. For example "table" appears in the list of stereotypes for EAUML. However, still no sign of "column" as either a metaclass or a stereotype...

Regards,

Look how the stereotype looks in the properties. You can simply create that by typing the EAUML::column (or whatever it might by) manually in a stereotype element name.
