Yes, I saw in your Haystak paper that you are using hs:TitlePredicate.

My idea behind using a special lens was that sometimes you might want to
1. combine properties like firstname and lastname
2. use alternative properties if dc:title is missing
3. use a thumbnail plus the title as general label

Thus I think using a lens might be more flexible.
