I am Chinmay, a GSOC intern at Crowdbio (http://www.google-melange.com/gsoc/project/google/gsoc2013/chinmay26/24001). Our goal is to create a bot to capture gene info in PBB templates (http://en.wikipedia.org/wiki/Category:Human_protein_templates) onto wikidata. We will be using Pywikipedia-bot framework. I am confused whether to go with Trunk or Rewrite branch. I am familiar with the Trunk and have queried wikidata items using it. On the other hand, there seems to be less documentation for Rewrite branch. I have installed the Rewrite as package from latest nightly release but not too familiar with it.

For our bot, we will be having normal functions like creating/updating items, claims, sources etc.(the Trunk seems sufficient for these functions). I have started coding with the Trunk but now i am a bit concerned about the lifetime about Trunk branch. Any chances it may be get outdated and then i would have to port to Release??

I am also concerned about the pace of development of the Rewrite branch. From another thread, I have noticed about changes to editEntity() to create items etc...
Should i use the Trunk or Rewrite branch ??
