Some have noted that the activity in my blog has decreased recently. Well, fortunately I'm still alive and well, although my workload is (even) higher than usual. That's why I have only posted once in this blog in the last two months. Some might say that's good because I'm contributing to reduce the noise in the net :)

One of the things I did in the last few weeks was to review the draft of the specification of RDFa. I've already posted some bits about RDFa (see this and this), I think it has the potential to become a widely used technology. So, when the W3C Semantic Web Deployment WG asked for reviewers for the draft specification, I volunteered. I did my best to spot any potential issue in the draft, and actually I sent a number of comments. Therefore, even if the merit is all of the editors of the specification, I feel that I have made a humble contribution to this new technology.

Some time ago I applied RDFa to my web page, mainly as an exercise to learn the technology. In the last days, I fixed some errors and I decided to drop my FOAF file and to replace it with an Apache redirect rule:

RewriteRule ^foaf.rdf http://www.w3.org/2007/08/pyRdfa/extract?uri=http://berrueta.net/ [R=303,L]

Additionally, I also included another redirect rule to allow non RDFa-aware semantic web agents to get RDF descriptions of my pages. This is the second rule:

RewriteCond %{HTTP_ACCEPT} application/rdf\+xml
RewriteRule ^(.*) http://www.w3.org/2007/08/pyRdfa/extract?uri=http://berrueta.net/$1 [R=303,L]

Once I finished implementing these ideas, I found that Ivan Herman had already done the same thing, and he posted the recipe in his blog. How could I have missed his post? Well, if you how I started this entry, I've been so busy these weeks that I haven't read my feed aggregator. Ouch!

By the way, I still have to check why Vapour says that there is a problem with content negotiation. When I check the same thing using curl or wget, everything seems to be OK. Maybe there is a bug in Vapour?
