There are a number of common situations where I would like to be able to classify an item with multiple values. Examples :-
A single story id that has multiple authors
A single story id that has multiple tags
A product that has multiple categories
A download that has multiple OS's
I would expect by default for full allocation of metrics based on the key value across each multple value.
Perhaps I misunderstand your request, but you can already sub-classify things. Granted, it's a little limited, but perhaps it will suit you?
When you go to create classifications, you can do like
And the template will look like this:
Key a a^aa a^ab b
This doesn't really allow for arbitrary amount of values..but perhaps it might help a little? Yeah..probably not.
