Linked railway data project - right now, I'm just querying dbpedia to
find an alternative URI for each station, so that I can provide
ovterms:similarTo links from one URI for the station to another. But in
the future I'd hope to also pull data about each station from dbpedia.

libre.fm - not using dbpedia yet, but it's being considered as a place
to find album art, artist biographies, etc.

Batch queries would be nice. Imagine that I want to find a particular
piece of information about multiple resources - e.g. the number of
platforms a train station has, for each station in a list I've got of
1000.

Right now I have two options, a single SPARQL query like:

	SELECT ?s ?o
	WHERE { ?s dbpedia:platforms ?o }

which might return hundreds of results for subjects I'm not interested
in; or querying each subject individually. The former is not the best
use of bandwidth, especially for properties like rdfs:label where there
are likely to be far more irrelevant results than relevant; and the
latter can't be especially efficient in terms of dbpedia's CPU time.

The other thing I'd like to see is some sort of better reasoning about
redirects. I don't know quite how, but there must be something better
than what we have now.
