Hi Markus et al. Thank you for the answer. I have a few follow-up questions as I'm not quite grasping the toolkit.
Alternative 1: So, if I'd like to do 1) I need a dump file, I've downloaded a *-current dump ( http://dumps.wikimedia.org/wikidatawiki/20150330/wikidatawiki-20150330-pages-meta-current.xml.bz2) and am trying to process it using the DumpProcessingController class - which I'm assuming is the wrong way to go about this. Is there a guide on how to parse local dumps? Alternative 2: I've been looking at the FetchOnlineDataExample and this seems to do pretty much what I need, except for retrieving interlanguage links for a page given the entity title - not the id. Is this possible, or is there a possibility of getting the entity id given a page title in a given language?
