Adding an app to a profile

Part of the RWW is a clean separation between apps, data and identiry.

I was wondering if there's a convenient single predicate to add a webapp to
a profile page.

Currently I use foaf : interest which isnt really accurate.

We were thinking about creating

plink : webapp

As per http://ontologi.es/

Any thoughts on this?

I think it would be awesome when we can finally start adding apps to our
pages.
