Back to Apache2
As I’ve got a lot of errors while running PHP scripts in FactCGI mode under LightTPD, and have not enough time to see what’s wrong with it (the scripts run fine in command line, but the webserver returns a 500 error when running it), I finally switched back to Apache2.
URL rewriting should have been enabled as it used to be, but tell me if there are any 404.

Anciennes URLs et 404
J’ai enfin pris les 3 secondes nécessaires pour mettre en place les redirections des anciennes URLs de alex.passant.org vers le domaine apassant.net, pendant qu’on y est, le directory listing.
Ca limitera les immondes 404 qu’on me signale un peu partout partout.
PHOAF v0.3 and foafMap future
I’ve updated PHOAF in CVS last week-end, and also as a v0.3 release.
Here’s the changelog:
- First, a bugfix about PHP5 warnings in RAP, as it uses reference when calling some methods. I fixed it in v0.1 but forgot to do it when upgrading RAP to 0.9.3[1]. Thanx to Jean-Jacques for reporting it
- Removing all useless code from RAP, so that the API will be lighter to embed in other apps. By useless, I mean that PHOAF doesn’t need all the features that RAP offers, as infModel, resModel … I also removed the SPARQL + RDQL functions. Indeed, the aim of PHOAF is to provide an easy way to parse FOAF files, using only PHP objects and appropriate methods. IMHO, if a user want to use SPARQL on FOAF files, it means that he knows RDF and SPARQL, so he’ll have better to use RAP directly instead of PHOAF. The archive is now only 91K, while it used to be 544k for v0.2 !
- the methode FoafModel->root(), which is used when you want to get the primary topic of the file can now retrieve not only people, but also groups[2]
- As a consequence of the previous point, I added a
getResourceType()method forFoafResource, so that you can check if your PPD is aPerson, aGroup, or anything else actually.
So, indeed, I’ll move it into foafmap soon.
The main interest is that it will be able to manage group files, as Tom suggested me. Then, I’ll put an optional cache system (as retrieving informations from distributed FOAF files over the network is a bit long). I’ll also add a user account system, so that users will be available to update their cached result, maybe tag their profile (with tag detection from foaf:interests), etc …
I think it could lead to a SemWeb equivalent to Frappr!, where the main advantage is that you own your datas, and the app is just here to display it on a map. I think that’s really better, for privacy and for decentralized knowledge management. If you or one of your friend change location, you won’t have to modify anything, just update your FOAF profile, reload your foafmap page, and that’s ok !
Notes
[1] RAP v1.0 might be rewritten in PHP5
[2] BTW, please use personalProfileDocument and primaryTopic when you create a FOAF file. That’s the better machine-readable way to tell who is your FOAF file about

Etat de la blogosphère - Février 2006
David Sifry (fondateur de Technorati), vient de publier son nouveau rapport “State of the blogosphere”. Pour rappel, Technorati est la plate-forme de suivi en temps-réel (grâce au système de pings) de l’activité de la blogosphère.
In summary:
* Technorati now tracks over 27.2 Million blogs * The blogosphere is doubling in size every 5 and a half months * It is now over 60 times bigger than it was 3 years ago * On average, a new weblog is created every second of every day * 13.7 million bloggers are still posting 3 months after their blogs are created * Spings (Spam Pings) can sometimes account for as much as 60% of the total daily pings Technorati receives * Sophisticated spam management tools eliminate the spings and find that about 9% of new blogs are spam or machine generated * Technorati tracks about 1.2 Million new blog posts each day, about 50,000 per hour * Over 81 Million posts with tags since January 2005, increasing by 400,000 per day * Blog Finder has over 850,000 blogs, and over 2,500 popular categories have attracted a critical mass of topical bloggers

(FOAF)Homepage online
My homepage is finally online, with a short bio and links to misc stuff (projects, bookmarks …). It’s generated from my FOAF profile, using PHP5 and XSLT.
As you may see, the XSLT stylesheet is really basic: it just parses the FOAF profile to render informations, loops around foaf:currentProject and foaf:onlineAccount, and sometimes test the lang parameter to display informations in french or english …
This is actually why is use PHP5 instead a simple stylesheet applied to the profile, as I autodetect preferend user language from the browser. Moreover, as one can embed PHP in an XSLT stylesheet with PHP5, I can retrieve the lang parameter, and also display last update, reading file information with filemtime().
DokuWiki URL rewriting in LightTPD
I’ve finally decided to setup DokuWiki as a personnal wiki, as it handles 2 of my first needs: namespaces and ACLs by namespaces.
Here are the options you need to set up to get clean URL rewriting in LightTPD.
In conf/dokuwiki.conf:
$conf['userewrite'] = 1; //this makes nice URLs: 0: off 1: .htaccess 2: internal $conf['useslash'] = 1; //use slash instead of colon? only when rewrite is on
The second line is optional, but I feel better handling namespaces pages with / - as subdirectories - instead of colons.
Actually, you can set option 2 (internal) for the userewrite parameter. Yet, URLs would be like "wiki/doku.php/mypage", and I’d prefer something like "wiki/mypage". In such a case (option 1), you need to set the following rules in lighttpd.conf:
"^/wiki/?$" => "/wiki/doku.php", "^/wiki/lib/(.*)/?$" => "/wiki/lib/$1", "^/wiki/(.*)\?do=(.*)/?$" => "/wiki/doku.php?id=$1&do=$2", "^/wiki/(.*)/?$" => "/wiki/doku.php?id=$1\
Toolkits pour le Web Sémantique
Je viens de tomber via planetrdf sur cette page recensant la plupart des librairies et frameworks pour le Web Sémantique. Je ne suis pas franchement sur que JavaScript soit l’idéal pour parser un graphe de plusieurs milliers de noeuds, mais toujours est-il qu’il existe des outils dans de nombreux langages.
L’article donne également une bonne idée de l’activité de chacun des projets, avec le nombre de développeurs, la dernière release, etc …
A bookmarker pour les intéressés !
PHOAF update
I’ve updated PHOAF so that it now includes RAP 0.9.3, especially for bugfixes as I don’t use SPARQL in the library. I’ve also added a few methods I forgot to implement before, as getHomepage(), plus the usual bugfixes.
PHOAF v0.2 can be downloaded here.
