Still alive (and reviewing)

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?
