How to pass a list (comma separated) to a traffic variable in Omniture?

I have a field "taxonomy" and I would like to pass it to Omniture. This Taxonomy field can have multiple values and I would like to calculate the count for each of the taxonomy separately. Let me explain my question with an example:

Item can be associated with multiple taxonomy. Letz say we are talking about an item called "Item1". This item can be associated with taxonomy "Tx1","Tx2","Tx3".

So the js code will be like,

s.prop1 = "Item1"
s.prop2 = "Tx1, Tx2, Tx3"

I was expecting omniture to store individual buckets/counters for "Tx1" "Tx2" and "Tx3". But Omniture created one bucket for "Tx1, Tx2, Tx3". I hope there is a way to treat them separately. Ideally I would not like to pass the taxonomies separately in separate prop variables.

I would appreciate if someone can point me in the right direction.

Thanks, Rag

Solution

Omniture does have the functionality you're looking for from version 15 onwards. Unfortunately it won't do it in a prop. You need to use a slightly different variable type. The variable you're looking for is a list eVar.

Every implementation has three of these available:

s.list1
s.list2
s.list3

Here's the blog post where Omniture introduced them. You can also find information on them in Knowledge Base article 10549 from inside the Adobe Marketing Cloud interface.
