Exactly.
Implementing variants of this problem in the past (and generalizing
from various other implementations), the general approach seems to be
hard-wired in code to look for (rdf:value, rdfs:label, dc:title) and
then punt to an in-your-face url of the 'thing'. I'm hoping we can do
better than that. :)
Haystack seems to have gotten this pretty close. How is this being done?
Haystack has something analagous to fresnel:label, namely
hs:titleSourcePredicate specifies, for a given class, which properties can
serve as labels.
As Emmanuel mentioned -
"... fresnel:label (or at least there is label in it, Chris or Ryan
will know better) and takes a URI reference (indicating a property) as
the property value to be considered as the label."
seems to be a start towards this.
There are various issues to watch out for with objects that are
multiple types (which in turn might have multiple fresnel:label (s) but
thats a different thread.
I just wanted to make sure this feature was in there somewhere. :)

Yes. In the case of not knowing the 'label', applications should
defaulting to some sort of additional helpful display. While this
default will be application specific in the case of Longwell /
PiggyBank / SemBank a linked version of the above is preferable to
'anonymous'.
