Comment 3 for bug 784478

The silent agreement in the Unity lens interactions is that the URI column is very free form and mostly internal (wow, can we get more sloppy? ;-)). We've introduced another address mechanism for results which is, for now, called the "external uri" - or maybe justifiably a URL. This external URI *must* be correct and addressable from the outside (hence URL makes sense). So I think we can document our selves out of this problem?

Robert Carr committed a fix to the apps lens to support this:
