All,
just in case people weren't aware, wiki-based documentation has been on the cards for a long time. I discussed this at both of the openforce conferences this year (including during the Q&A session), and have mentioned it on a number of forum posts (such as http://www.dotnetnuke.com/Community/Forums/tabid/795/forumid/118/threadid/276918/scope/posts/threadpage/2/Default.aspx) , but it seems that noone on this thread was aware of it (core team members excluded naturally), so thought I'd post to give a little background.
I've long been a proponent of a wiki on dotnetnuke.com (Oliver, I appreciate what you're trying to do with your wiki, but without wanting to seem overly negative, there have been 3/4 similar efforts over the years which have met with similar lack of success, I guess as people expect/want a wiki to hang off dotnetnuke.com). In fact over a year ago , we piloted the core wiki on dotnetnuke.com to run it through it's paces, and see if it was fit for what we needed i.e. a resource that the community could add to. The wiki itself didn't end up with too much content as only a few of the core members such as Sebastian that regularly reply to forum posts added content, though one or two pieces were added by people such as Joe after they'd added new features to dotnetnuke, so it had some value. However, the core wiki itself was/is not mature enough for our purposes. The primary problem was that it didn't support rollbacks so it would be trivial for hackers/unhelp users to delete/ruin content.
I began to evaluate a number of asp.net based wikis, and liked the look of screwturn wiki, as it had all the features we need, plus others such as transclusions, delegated authorization and discussions that we could leverage. It also has support for an authentication provider model, which is important to allow us to leverage the existing dotnetnuke.com users/roles. However, the problem here is one of time/effort - I simply have not had the time( having to earn money to pay the bills has precedence), but it's on the cards.
One thing to note about a wiki as a documentation source, is that not everyone wants to post to a wiki. Wiki's tend to be very altruistic, as unless someone clicks into an article history, then content has no "owner" (and therefore little credit). Many people create quality content for dotnetnuke, but want to reap benefits from it by posting it on their own website e.g. google adword revenue, community credit, building a reputation (for mvp/business) or other reasons, so are likely to be reluctant to post their content on a core wiki. The core documentation project mentioned here http://www.dotnetnuke.com/Community/Blogs/tabid/825/EntryId/2031/DNN-Days-of-Yore-or-how-massive-DotNetNuke-is-becoming.aspx will be an attempt to capture this documentation sources but allow the content creators to still gain their benefits i.e. it's an index of documentation but the content still lives where the content owner wants it to do.
