I have been waiting for information about what progress has been made with
the community based infobox extraction framework. Then the relevant
predicates in the protein/gene/chemical infoboxes can be used pretty easily
for linkages.

I do understand the difference, but I tend to use the term mashup for any
combining of the data sources independent of the presentation. Its hard
enough defining a mashup when people ask for a definition without going for
another similar term from my experience.
