SMW implementation + MW code drop megathread
I think there are a few of us coming to understand the SMW formats now. One issue that comes up when you're adding SMW to existing Categories is that we have to manually purge or re-save every page in the category to get the SMW variables to populate. If you add a new property or even change the data type of a property, the entire category has to be purged to reflect that change. I'm not sure if there's an SMW action I can't find or if there's some PHP you can personally wrangle that might help on that front.
I've converted http://zoywiki.com/LotS/items/Officers to use SMW and reduced 339 expensive parser calls to 0, and cut the generation time by ~80%. There are still a few things left to learn, but I think we're on the right track. If you have a list of priority items that we should focus on first, we can tackle them in order.
