I've noted some more comments about widget integration in general, but nothing as specific or useful (IMHO) as a project to integrate http://www.google.com/friendconnect/ ( http://www.youtube.com/v/N94s7ix0JPo&hl=en&autoplay=1 ) with Xwiki. That way people with the appropriate ID/credentials compatible w/ google friendconnect's OpenID would be able to login and leave authenticated comments on a wiki. A while back Thilina Buddhika ( http://www.mail-archive.com/[email protected]/msg07563.html ) expressed interest in this subject on this list; I was wondering if that interest continues, or if others might find this an interesting pursuit for GSOC 2009. The user experience should be that those w/ openID credentials should get an automatic login into Xwiki, and that the same authentication would also drive the friendconnect "widgets." I think the widgets themselves could easily be integrated into Xwiki's existing panel system. Therefore, the main work would be in creating a smoothly-integrated OpenID-based auth system giving appropriately credentialed users an automatic "authenticated guest" login. This login allows authenticated comments and registration, making commenting much easier and straightforward in Xwiki. Also, registration could always associated with a real user and not a spam account at mail.ru... Although the construction of widget "panels" itself might be simple, some of the authorization issues might be thorny. For example, do you publicly display your friends-list-widget-panel to all unauthenticated users and search engines, or do only logged-in users get access? Likewise, when "friends" log in or view your site, they might automatically receive special privilege based on their authenticated-friend status, e.g. view-access to a private part of the wiki, for example. This might require extension of the Rights system in Xwiki with extra roles alongside "unathenticated user", such as "openid authenticated user" and "openid authenticated friend." ...

I am also planning to apply for GSoC 2009 (yet to be announced) and I have realised that XWiki is a challenging and promising open source project for GSoC 2009. When watching the developer list, I found this mail by Niels Mayer with the subject,* "Social Networking via OpenID support in Xwiki?"*. And It looks like an intersting idea. I also found that there was a GSoC 2008 project related to this idea [1]. So is it possible to continue this project further? Other than the above idea, I would like to know the other possible project ideas for GSoC 2009. If it is too early I am posting about this, then lets leave it for the next couple of weeks. Anyway I am trying to get familiarized with Xwiki until the GSoC 2009 is announced.

Of these, which has the easiest to integrate: http://www.google.com/friendconnect/ http://developers.facebook.com/connect.php

Friendconnect has always looked most interesting of the lot, since it will give you a variety of customizable friendconnect "widgets" . Once you request and customize a particular instance, google generates the code and presents it in a scrollable textarea.

Reusing the framework of one of Xwiki's existing panels is a good way to wrap Google Friendconnect socialnetworking into an Xwiki site. You'd basically take the code and paste it into the panel document. Then layout one or more of the google panels into the "sidebars" in Xwiki. This permits xwiki to layout the friendconnect panels as if they were :"one of it's own."

Probably the easiest first-experiment would be to take an existing panel that you probably don't use, like /xwiki/bin/inline/Panels/Welcome; as 'Admin' click "edit" and then paste in the google code between #panelheader("Welcome") and #panelfooter(). Later, create more via http://nielsmayer.com/xwiki/bin/view/Panels/CreatePanel ...

I haven't looked at friendconnect's OpenID implementation so I don't know how it would coexist or overlap w/ Xwiki's auth. I'd assume you'd create an implementation per

http://svn.xwiki.org/svnroot/xwiki/platform/core/trunk/xwiki-core/src/main/j... follow instructions in

http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Authentication#HCustomAu...

You mentioned GSOC 2008 and http://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/SSOAndOpenIDSupport ... what is the status of any code completed to date?

............................... Vincent Massol: I'm pretty sure we'll all want to have widget integration as a GSOC

2009 project (open social, etc).

............................... Thomas Mortagne:

The OpenId authenticator and provider already works pretty well based in the current not very clean authentication api with some hack

because Markus did not had choice to do this otherwise. I just did not had time to integrate it yet in the trunk but Raffaello Pelagalli started do to some test with it to integrate between http://l10n.xwiki.org and xwiki.org farms (l10n is on its own instance

of XWiki).

See http://jira.xwiki.org/jira/browse/XWIKI-2630 , http://jira.xwiki.org/jira/browse/XWIKI-2588 and http://jira.xwiki.org/jira/browse/XSALBATROSS-34

.................................. Markus Lanthaler:

Right. The implementation is complete but I guess the tests are still missing (kind of difficult to write meaningful tests for it).

The implementation supports both, RP and server. XWiki can accept OpenIDs from other sites as well as issue OpenIDs to be used on other sites supporting OpenID. That way you can use your XWiki account all over the web

(well at least on sites that support OpenID).
