Syndicating trust? Mediawiki, WordPress and OpenID

Fancy title but simple code. A periodic update script is setting user/group membership rules on the FOAF wiki based on a list of trusted (for this purpose) OpenIDs exported from a nearby blog. If you’ve commented on the blog using OpenID and it was accepted, this means you can also perform some admin actions (page deletes, moves, blocking spammers etc.) on the FOAF wiki without any additional fuss.

Both WordPress blogs and Mediawiki wikis have some support for OpenID logins.

The FOAF wiki until recently only had one Sysop and Bureaucrat account (a bureaucrat has the same privileges as a Sysop except for the ability to create new bureaucrat accounts). So I’ve begun an experiment exploring idea of pre-approving certain OpenIDs for bureaucrat activities. For now, I take a list of OpenIDs from my own blog; these appear to be just the good guys, but this might be because only real humans have commented on my blog via OpenID. With a bit of tweaking I’m sure I could write SQL to select out only OpenIDs associated with posts or comments I’ve accepted as non spammy, though.

So now there’s a script I can run (thanks tobyink and others in #swig IRC for help) which compares an externally supplied list of OpenID URIs with those OpenIDs known to the wiki, and upgrades the status of any overlaps to be bureaucrats. Currently the ‘syndication’ is trivial since the sites are on the same machine, and the UI is minimal; I haven’t figured out how best to convey this notion of ‘pre-approved upgrade’ to the people I’m putting in an admin group. Quite reasonably they might object to being misrepresented as contributors; who knows.

But all that aside, take a look and have a think. This kind of approach has a lot going for it. We will have all kinds of lists of people, groups of people, and in many cases we’ll know their OpenIDs. So why not pool what we know? If a blog or wiki has information about an OpenID that shows it is somehow trustworthy, or at least not obviously a spammer, there’s every reason to make notations (eg. FOAF/RDFa) that allow other such sites to harvest and integrate that data…

See also Dan Connolly’s DIG blog post on this, and the current list of Bureaucrats on the FOAF Wiki (and associated documentation). If your names on the list, it just means your OpenID was on a pre-approved list of folk who I trust based on their interactions with my own blog. I’d love to add more sources here and make it genuinely communal.

This is all part of the process of getting FOAF moving again. The brains of FOAF is in the IssueTracker page, and since the site was damaged by spammers and hackers recently I’m trying to make sure we have a happy / wholesome environment for maintaining shared documents. And that’s more than I can do as a solo admin, hence this design for opening things up…
