This will be a required step for finalizing the vision described in my SMWCon fall 2011 talk, the other month.
I developed RDFIO as part of Google Summer of Code 2010, and it got into a working proof-of-concept state. Some issues, such as with performance, never were resolved though. Also it depended upon two other modules, which, after Semantic MediaWiki changed a lot of it's internals in version 1.6, have still not been updated to support these, leaving RDFIO in a state where it does not support SMW 1.6.
So, a little sprint is definitely needed, to get RDFIO in working condition again. At the same time I hope to look at it with fresh eyes, after having a lot more coding experience now, than when I coded RDFIO, after one year of quite some Java and Python development in my work at UPPMAX.
Things I plan to have a look at (or at least ponder):
I would love to get some feedback and input to the project during this intensive week, so don't hesitate to drop in at #semantic-mediawiki on irc.freenode.net (IRC chat) or in the SMW-devel mailing list! My contact options, summarized:
Looking forward to your input during this week!
