One of those principles could be rephrased as: Why use XML when (X)HTML will do?
Perhaps another could be rephrased: Why bother with parsing/transforming when you can just get the data in a presentable format? After all, we all know that less code is better.
AHAH (Asychronous HTML and HTTP) is the result of applying both of those principles to the incredibly Web 2.0 buzzworthy AJAX. Strictly speaking, AHAH is simply a subset of AJAX, albeit a subset that openly de-emphasizes the X in AJAX.
AJAX Magazine provided a good overview of the advantages of AHAH over “traditional” XML-based AJAX.
So if you’ve been wondering what this AJAX stuff is about, take a look at AHAH, you might find it gets you 90% of the hyped user interface advantages with only about 10% of the hype (and effort for that matter). That’s the kind of 90/10 rule we like around here.
But don’t take our word for it. See what others have been saying about AJAX and AHAH.
The two day Syndicate Conference finished up yesterday. Lots of good news about microformats and more and better support for microformats was announced both during the conference and the weeks leading up to it. I’m still collecting/collating all the recent announcements.
For now, check out the following:
- Microformats: Emerging syndication types presentation at yesterday’s microcontent panel.
- The Structured Blogging plug-in(s)/extension(s) have been updated to support several microformats including hCalendar and hReview.
- Beta versions of a Contacts Feed Service and Events Feed Service (using the most excellent X2V Proxy code written by Brian Suda) to allow automatic conversion and import and subscriptions of hCards and hCalendar events into desktop address book and calendaring applications.
- Contribution of all previous Attention.xml specification/format work to microformats.org by Attensa and Technorati with the understanding that it must undergo the microformats process and thus may be completely rethought and rewritten. See the attention page for more info.
And that’s just a taste. More to follow.
Another note in my very-neglected series on Semantic XHTML basics started awhile back.
It seems that everytime I present microformats, I need to explain the difference bettween the rel and rev attributes. Its understandable that most people don’t grasp the difference, as I’m sure most webdevelopers haven’t needed to make use of these semantics.
First of all,
rel is an attribute which can be applied to
<link> to define the relationship between the linked document and the current one. So, a very common example is a link to a feed. This blog has:
<link rel="alternate" type="application/rss+xml" href="http://www.microformats.org/feed/" />
This can be read as
http://microformats.org/feed/ is an
http://microformats.org/ (Incidentally, the feed could link to this blog with
rev="alternate", which would have exactly the same meaning. More on
rev in a minute.).
rev is just like
rel, but the relationship is reversed (I think of rev as “reverse relationship”). It gets used in the vote-links microformat like this:
<a href="http://supr.c.ilio.us/blog/" rev="vote-for" title="supr snark">supr.c.ilio.us rocks!</a>
…which would be read as “this document is a vote-for http://supr.c.ilio.us/blog/”.
rel and rev are useful for describing the relationships between two resources on the web. Remember, it is only the relationship between the documents, not the documents themselves which are described. Describing the documents themselves is another topic altogether.
Again, see the wiki for more info.
