SEO: Semantic Web

Post by alledia » Tue Mar 25, 2008 4:55 pm

Short description

Improvement of the default output markup generated in order to comply with W3C (X)HTML recommendations (both in terms of validation and of semantics). Also, the addition of more high-level semantics such as Microformats.

Expected benefits/ Problem solved

Allows the search engines to better "understand" the content they are reading and therefore the search engines are able to produce more relevant search results for Joomla! sites. There are also various benefits for accessibility.

Potential issues

None so far.

If you've watched my blog the past couple of months, you know I've been looking into these topics quite a bit and proposed a few SoC projects.

The problem with the "Semantic Web" is that it isn't "a thing" that can be requested to be "added" to v 1.6. For one, is this a request that J! serve server or client services? Think of this as an RSS feed - in the early stages - where we had no clue which protocols were going to dominate. There are so many directions you could head with it and, frankly, it's not obvious which is the best way to go. You'll even see HUGE diversity of options coming out of the MIT Lab with Berners-Lee and clearly this stuff is his vision.

Initially, when I started looking at this topic, I thought Microformats were "the way" to proceed. And, I think for a blogger, there are some fun connections that can be made using hcard and XFN (which, BTW, WordPress has used for years as their Web links environment.

I think once you start getting into xoxo, though, there is little value since it's not consumable (mashable) by many applications - and - that's where you start seeing RDF and SparqlEndpoints start to look very promising.

Microformats can be easily implemented using template overrides. In fact, it was Charl's 2007 SoC project. I'd love to see him update it for v 1.5, like he had planned, and get those overrides out there where the community can begin exploring the value.

Meanwhile, let's hope we get a few students this year to explore RDF more deeply. That must be combined with analysis in the Data Portability arena, as well.

I'm closely tuned into Drupal's Semantic Web discussions. They are covering a ton of options and exploring in lots of areas. Also, Plone has been very involved with Dublin Core for a long time and we might want to consider what benefits that approach could take.

This is the future - just can't tell where it's going. On the plus side, template overrides position Joomla! for *lots* of different approaches and the more people start digging into this and creating extensions, the better able we will be as a community to figure out what works best for which types of applications.

In short, I do not believe we are anywhere close to being ready for 1.6. Further, I do not believe the industry is close, either, for inclusion into core. But, I do think it's high time we start building extensions using template overrides and test out Triplify and xmlgrddl and get some discussions and research underway so that we can offer web services and get ourselves mashed up. ;)

This is certainly the future.
Amy :)

This was actually Charl's suggestion ... I'll give him a ping and get him over into this thread.

Well there is some tools and solutions out there and hope this will not be forgotten for Joomla.

There is one potential problem that many are not seeing. This has the potential to eliminate the "Search Engine Optimization" industry in the coming years. RDFa is just a tool that "web developers" should be including for their clients from this point forward. While those who know about it have an advantage, it is a drastic step in leveling the playing field. Next thing you know, Google and others will put out documents on how to properly promote your website and business online.

I know if I sat down I probably could write at least 10 pages of information on how to properly promote any "brick and mortar" or "internet sales site" through the web. A short, but concise reading on how to properly promote your business on the web should not be that hard for anyone that has been following web trends for the last few years.

Knowing all the ins and outs of search engine "basics" isn't hard to find through one Google search. Couple that with forums and other means that are all becoming common practice and soon all the "secrets" will be out.

If a web developer entering the playing field can follow simple instructions and read what's needed, why couldn't he develop a website just as "seo friendly" as his competitor? Sometimes getting the rankings takes a little bit of time, others a lot longer. It really depends on the nature of the business and it's reach, or lack there of. I'm for the organization, but unless you develop a modern miracle of a website... you're going to have a harder and harder time getting noticed.


When it becomes standard and everyone knows how and why to do it, you're not going to get paid for being ahead of the curve anymore. The curve does not exist any longer. This will however revive the web developer industry as they promote the service to upgrade your site to standard "search engine compliance"...

What is the plan for supporting RDFa in the near future now that Google and Yahoo are on board with it? What are my options currently with 1.5.x to add RDFa support other than encode it in my article markup?

I dont think that validation matters at all to SEO. Check Googles HP, they have a bunch of errors.

jduley,there is a very skilled guy Danh Le Phuoc PhD at DERI, National University of Ireland Galway that did a GSOC 2008 project for Joomla community but he disappeared http://developer.joomla.org/gsoc2008/se ... ncast.html.

He extended this into semantic web "pipes" http://pipes.deri.org/ now like the Yahoo pipes structure http://pipes.yahoo.com/pipes/ so I dont think he is thinking any more about Joomla unfortunately. He have remove his files that you could dl before too for testing his work for Joomla :'(

But this is very interesting and it would be good if Joomla community could have good contacts with this guy.
