Open Stack

You bring up a good point Thomas. I think some of the discussions are
mixing template and stack perspectives, they are not the same thing, stack
== instance of a template. There likely is room for "tagging" stacks, all
under the control of the user and meant for user consumption, vs the long
going discussion on template-level metadata. This may be yet another use
case ;-)

Thanks, that clarified the use case a bit. Bot looking at the use case now,
isn't this stack tagging instead of template tagging?
I.e. assume that for each stack a user creates, he/she can assign one or
more tags so you can do better queries to find stacks later?

Regards,
Thomas
