I was asked about licenses and wiki software, by someone wanting to start a wiki on a sustainability-related subject area. Here is part of the response I wrote (adapted slightly):
Not all licenses are compatible, so unfortunately there are some limitations. We can each share, but we can’t mix the content together. The Some sites uses the CC-BY-NC-SA, and we, like Wikipedia, use CC-BY-SA*. We don’t use the NC or non-commercial clause, as we would actually like people to use our content commercially or any other way. I’ve made some notes on an Appropedia page: Which open license should you use? There is a place for the NC license, and I can understand someone with a business choosing this license, but for most purposes we’re strongly in favor of CC-BY-SA.
* Actually we use GFDL, which is different in some details, but you can expect both Wikipedia and Appropedia to change to CC-BY-SA in coming months, now that this has been allowed by the people that manage the GFDL.
We do both use the share-alike clause – which prevents someone adapting our work and then not sharing the adaptation.
I can see the appeal of the subwiki system that PmWiki uses, to allow communities to have their own space in the wiki. It seems to me that there are just a few things that PmWiki does that MediaWiki does not – although they are very nice things. We can set up pages in just the same way if we want, but don’t have the ability to adjust the sidebar and don’t have the RecentChanges for just the subwiki. Though with “Related Changes” MediaWiki has something close. We do hope to have the options to do these things through MediaWiki extensions, but I don’t know when that will happen.
MediaWiki is the most established option, but certainly it’s not the only reasonable option. We’ve heard good things of TikiWiki too.
But we like MediaWiki for a few reasons:
- It’s well-supported, with mailing lists and websites devoted to it, and there are many extensions written
- Being so popular, we can be sure the format will be supported in future.
- It’s well tested. Wikipedia: nuff said.
- Appropedia is a bit more like Wikipedia but wider in content type, in aiming to be a large and comprehensive compendium of knowledge, projects, how-tos etc, on permaculture, passive solar, hybrid vehicle design – you name it. For such a large project, something proven to work on massive projects is preferred.
- We know MediaWiki (I was active on Wikipedia before Appropedia), and collaborators from the wikisphere know MediaWiki. Easier to contribute, and to manage the site.
The major drawback to MediaWiki has been the lack of a WYSYWYG editor, but that’s changing now with the FCKeditor extension. This is usable now, but we’re waiting until they’ve resolved all the issues with tags (as we tend to use tags a lot, e.g. reference tags <ref>).
Now as for a wiki on your particular area of sustainability & resilience – that is right up our alley, and we’d love to have more about this on Appropedia. Check out Appropedia before you start up anything. You will probably find, as with Vinay Gupta, inventor of the Hexayurt (flatpack emergency shelter) that running a wiki takes hours every month – he was glad to hand that over to someone else when he joined his wiki with Appropedia. Joining an existing wiki brings you into a network of like-minded people, and lets you work on the project you love, rather than pulling your hair out managing a website.
Or to put it another way, let us go bald on your behalf.
But regardless, keep in touch. Also check out Global Swadeshi – a very interesting forum site on open design and open technology for resilient communities, started by the same Vinay Gupta.
