Indeed. I made this temporary change on WikiSPARQL, so that links like in Jean-Baptiste's examples may work "properly". If you try this:
http://wikisparql.org/sparql?query=DESCRIBE+%3Chttp%3A//www.wikidata.org/ent...
and then click on the external link on any property, now you should be redirected to the "right" wiki page.
Nice, here is a query to make good use of this:
"All properties used on Wikidata to connect too humans, ordered by the number of times that they are used in this way"
http://wikisparql.org/sparql?query=PREFIX+%3A+%3Chttp%3A%2F%2Fwww.wikidata.o...
Most of the properties with less than, say, 5 uses are probably errors (one could do other queries to find out which humans have this particular connection).
As soon as we have the explicit links to the property entities, it will also be possible to create the (more useful) list of property labels.
By the way, if you can control the output UI completely, you may consider adding this: instead of a property or item URI, always display its label (in a selected language), and merely show the URI as a tooltip or similar. This could be done after querying with Javascript so that people don't need to do many join+filter parts in queries just to retrieve the labels.
