<p>After the <span class="caps">RSS</span> feeds being restored, I took the chance to add some new stuff to my online identity. I use <a href="http://kveton.com/blog/2008/01/03/urls-are-people-too-and-service-end-points/">this <span class="caps">URL</span> as an endpoint to all my online activity</a>. My hCard information is here, my <span class="caps">XFN</span> friend list is here, the links to all my profiles in several online services/social networks are here. It even works as my <a href="/tag/openid">OpenId</a>.</p>

<p>For the past days, I&#8217;ve been checking up on <a href="/tag/foaf"><span class="caps">FOAF</span></a>. There is already <a href="http://alcidesfonseca.com/blog/232">one opensource social network</a> accepting this format to import all your information. There is a bit of discussion between <a href="http://www.google.com/search?q=xfn+vs+foaf"><span class="caps">XFN</span>+hCard versus <span class="caps">FOAF</span></a> since the two of them represent your personal information and the relationship you have with others. I believe more in the microformat way of displaying data, but <span class="caps">FOAF</span> follows <span class="caps">RDF</span> standards.While <a href="http://danbri.org/">Dan Brickey</a>, one of the authors of <span class="caps">FOAF</span>, believes there is space for the both of them, I still have my doubts&#8230; Either way, I did <a href="/foaf.rdf">my own <span class="caps">FOAF</span> file</a> with basic info and then linking to the <a href="http://apassant.net/blog/2008/01/12/one-foaf-fits-all/"><span class="caps">FOAF</span> files extracted from my last.fm, twitter and flickr profiles</a>. If you want to make yours, you can write by hand or you could use <a href="http://www.ldodds.com/foaf/foaf-a-matic"><span class="caps">FOAF</span>-O-Matic</a>. For wordpress users, there is already <a href="http://www.wasab.dk/morten/blog/archives/2004/07/05/wordpress-plugin-foaf-output">one plugin</a>.</p>

<p>If you are interesting in learning about RDFa (a formal way of defining everything! in semantic web) and a bit about <span class="caps">FOAF</span>, make sure you see <a href="http://www.youtube.com/watch?v=ldl0m-5zLz4">this simple video</a>.</p>

<p>Next, I decided to implement my own <a href="/blog/200"><span class="caps">APML</span></a> file from all the tags I use in my blog. <a href="/apml.py">The result</a> is already linked in my head tag and I am waiting to use it in some projects. Imagine filtering through your feeds based on what you post (that is probably what you like!). Yes, there is also a <a href="http://wordpress.org/extend/plugins/apml/">wordpress plugin for this too</a>. And then I just adapted the code to serve as a tag cloud in the sidebar. But the evening hacking wasn&#8217;t finished until I add the last delicious entry for each tag page.</p>

<p>I hope in less than 6 months I have a daily usage of this stuff I&#8217;m working on. It would be a shame if when I register in a website it doesn&#8217;t import all my public info :(</p>
