Being a fan of the so called Semantic Web and knowing the long way we still have to track to reach it, all the things that takes us a bit closer to it has me on board. So it has been with Microformats, I had played a bit with Structured Blogging before but rapidly moved to what was ended up being known by Microformats for their multipurpose and not just for blogging.
A brief introduction for non-geek persons about Microformats and why they’ll became ever so important: The web is full of information, trapped information, hidden relations, hidden contents, consider for instance a simple news article, a review in a product page, that information is trapped under the rumble of it’s page HTML. Not nice, isn’t it? Through the separation of layout/content we already improved, since we can read each one of those examples hiding the details of the document structure focusing on the information thats important!
Being intelligent beings as we tend to consider ourselves, we have the ability to spot which parts of the information are relevant, if I look at a contact page, I immediately search for something that looks like an address, phone or email contact. It’s something we’re used to. Well the problem raises that when it matters with information we really can’t depend on humans! 
To a program reading a regular webpage, all that rumble and layout information, etc. is just the same! That’s were Microformats became essential! They allow us to seemingly “format” that information, so that humans and machines alike are able to extract the REALLY important parts! Microformats are much more than that, but for today’s introduction that the key idea to retain.
After some of the big companies embraced them a few months ago, Microformats seemed to be on the right track for massive adoption, and yesterday the all mighty W3C (World Wide Web Consortium) seems to have given a step the consolidation of Microformats by providing a set of use cases (GRDDL) that provide real-world scenarios and examples of Microformat in use, as they quote it:
(…)
GRDDL is the bridge for turning data expressed in an XML format (such as XHTML) into Semantic Web data. With GRDDL, authors transform the data they wish to share into a format that can be used and transformed again for more rigorous applications.
(…)
Once data is part of the Semantic Web, it can be merged with other data (for example, from a relational database, similarly exposed to the Semantic Web) for queries, inferences, and conversion to other formats.(…)
I strongly suggest reading some of thew3c use cases:
As complementary to the Microformats Website, the nice to have in hand Microformats Cheat Sheet and the book written by John Allsopp: “Microformats: Empowring Your Markup for Web 2.0 “
For people reading this here in the Portuguese quarter I promise that in coming weeks you’ll get your opportunity to learn a bit more about Microformats! enough said!

Joseph Smarr, Marc Canter, Robert Scoble, and Michael Arrington co-authered a proposal for a Bill of Rights for users of the Social Web/Networks available under the Open Social Web website.
According to this proposition for a bill of rights, every Social Network and/or Application should guarantee 3 fundamental USER rights
- Ownership of their own personal information: own profile data, the list of people they are connected to and the the activity stream of content they create;
- Control of whether and how such personal information is shared with others; and
- Freedom to grant persistent access to their personal information to trusted external sites.
which in practice means that this services should display the following features:
- Allow their users to syndicate their own profile data, their friends list, and the data that’s shared with them via the service, using a persistent URL or API token and open data formats;
- Allow their users to syndicate their own stream of activity outside the site;
- Allow their users to link from their profile pages to external identifiers in a public way; and
- Allow their users to discover who else they know is also on their site, using the same external identifiers made available for lookup within the service.
As further reading about this interoperability problem between different services and networks, I strongly suggest that you watch both Brad’s Fitzpatrick slides and read his “Thoughts on the Social Graph”:

Here’s something that I’ve been using to create new types of feeds from existing feeds.I’m using it right now to create a unique photolog that combines photos from different fotosharing sites, but I’ve also built my own news feed by combining the feed from diferent media sources in portugal, sources I’ve selected, kind of my own editorial feed, where I only get news from those I’ve decided to listen for.

Since the list of blogs I read on a daily basis is getting bigger and bigger, I decided some months ago to subscribe them via RSS, to keep updated with all the new posts.
It has happened to me, while reading some of the posts that I really would love to comment, but that implies clicking on the news-reader, opening the page, sometimes even click on the comments links, and only then I’m able to post my comment, I must confess I have kind of small short term memory, so by the time I get to the comment form, I already forgot about what I wanted to say!
Today I just noticed that Russel’s feed included a nice HTML form in the bottom of every feed entry:
Hey, that’s an interesting idea! So I decided to give it a try and put to work the same concept here on Centopeia.
Since this blog is powered by wordpress right now, rss feed are built by the following script files, depending on the type of the feed:
- atom.php: Produces Atom syndication output.
- wp-rdf.php: Produces RDF syndication output.
- wp-rss.php: Produces RSS syndication output.
- wp-rss2.php: Produces RSS2 syndication output.
So i decided to give it a try, starting from the RSS2 syndication. A carefull look at the code and I determined the place where the new form should go in:
<content:encoded>
<![CDATA[<?php the_excerpt_rss() ?>]]>
<?php include(’rsscommentform.php’); ?>
</content:encoded>
and included a call to “rsscommentform.php“, which has the html code necessary to produce something like:
at the bottom of every feed entry. Everything seemed to work fine, at least according to FeedValidator the rss feed is ok!
UPDATE: I’ve just removed the form from the rss2 feed, I’m having trouble configuring it with the Wordpress comment engine, so that people might comment comming from their favorite newsreader. Some how the comments don’t get posted…
