I'm sorry, I didn't mean to criticize. What I was trying to do is to validate that list=backlinks and prop=categories are querying for the same relationship if the backlinks namespace is set for categories, using blnamespace=14. If they were two ways to query for the same relationship between pages, then the results should be the same, but they are not.
I've been able to verify that prop=categories returns the correct relationship, because the inverse (list=categorymembers) returns the inverse result. If prop=categories indicates that A is a parent of B, then list=categorymembers correctly indicates that B is a child of A.
So what I'm trying to do is find the same relationship for portal pages (namespace=100). list=categorymembers also correctly returns the children who are portals, but I don't know how to find the parents that are portals.
Thanks in advance,
Robert

Thanks André, but after testing it seems that backlinks returns something else. For example this query:
http://en.wikipedia.org/w/api.php?action=query&titles=Category:Voltaire&...
Returns:
<query> <pages> <page pageid="3465227" ns="14" title="Category:Voltaire"> <categories> <cl ns="14" title="Category:Categories named after French people" /> <cl ns="14" title="Category:Categories named after philosophers" /> <cl ns="14" title="Category:Categories named after writers" /> </categories> </page> </pages> </query>
But this query:
http://en.wikipedia.org/w/api.php?action=query&list=backlinks&bltitl...
Returns:
<query> <backlinks /> </query>
If I just use "Voltaire" instead of "Category:Voltaire" then I think it's looking at a different page, right? The results are different, and don't match the first query results:
<query> <backlinks> <bl pageid="3465227" ns="14" title="Category:Voltaire" /> <bl pageid="15582893" ns="14" title="Category:Novels by Voltaire" /> </backlinks> </query>
You criticize my request because another request does not give the same result as a third request... I understand less and less of what you are trying to do.
