MDG Meta-constraints

[OpenIT Solutions]

Hi,

I'm just looking at replacing my Quicklinker CSV with a meta model (stereotyped relationships etc). One bit i can't figure out from the docs and various vidoes out there - if i use the quicklinker on a diagram and drag to an empty space - how to i specify which valid element stereotypes and connectors to display ? Any hints ? Docs that explain ?

Regards,

Jon.

I would guess that any metarelation you define would result in a new entry. However, I don't know by heart. If you figure it out, let us know :-) I'm just (again) starting to struggle with that.

When you define metaconstraints and stereotyped relationships you define which what is legal.

Those legal relationships will then be filtered to match what's in the current toolbox. Unless you turn off the filter to toolbox option.

Hi,

I have defined a stereotype relationship between two element stereotypes i have defined. If a place the two elements on a diagram and use the quicklinker to add a relationship, my stereotyped relationship is on the quicklinker. All good. However if i drag the quicklinker from a stereotyped element to empty space on the diagram, the quicklinker does not offer/contain my second stereotyped element. Its the latter bit that i can't get to work. Any clues / tips ?

If uncheck Filter to Toolbox, i'm presented with the element to create on the quicklinker. The elements and connector are in the toolbox however. So unclear what i've done wrong here...

My element stereotypes have a Class metaclass and the relationships has a Dependency metaclass, with meaning forweard/backward defined.

Regards,

Jon.

Hi,

I don't know if it's the whole issue, but you have your <metaconstraint> in the wrong place. Add two metaconstraints to the dependency stereotype, one with umlRole="source" and one with umlRole="target", pointing to the problem and solution stereotypes respectively.

Hi KP,

I've applied changes you sugggested. Still no joy :-(. See updated / generated mdg xml below. Any other suggestions please ?
