Aro | Your Mobile Life, Better Fuel your fascination What’s Best: Microformats, RDFa, or Micro Data? | SEMClubHouse - Key Relevance Blog In a recent post by Mike Blumenthal about Google’s announcement of supporting Microformats for local search, Andy Kuiper asked in the comments whether it would be best to go with Microdata versus RDFa or Microformat for marking up local business information. As the number of flavors of semantic markup have grown, I think Andy’s not the only one to wonder which markup protocol might be ideal. Here’s my opinion. When you’re asking “which is better?”, it’s important to know what we’re speaking-of, since there are a number of different goals that people could be pursuing. It’s this last orientation of the question that I’m focusing upon — which semantic protocol is going to work best for Search Engine Optimization (“SEO”)? Now, you might think that since I was probably the earliest marketer to recommend using Microformats for SEO that I’d feel so “invested” in the protocol that I might push it exclusively. So, which is best for SEO purposes?
RDFa vs microformats from Evan Prodromou I'm fascinated by the idea of including semantic markup in Plain Old XHTML pages, and I'm excited by recent developments in this area. But I'm also concerned about the growing discrepancy between the W3C's initiative, namely RDFa, and the more established but conversely less official microformats effort. I think that having competing standards efforts in this area is going to hurt the advancement of so-called small-s semantic Web technologies, which is going to be bad for everyone. Using XHTML as its own metadata substrate makes for some interesting applications, some of which are starting to disseminate on the Web. On the surface, the two systems are remarkably similar. But the two projects have different histories, and those histories are influencing their style and their future. RDFa, on the other hand, has been a long-smoldering concept of the W3 Semantic Web group and its associated thinkers. Examples An example is probably in order. Now, here's the same data encoded with RDFa:
Microformats The Open Graph Protocol About RDFa - Webmaster Tools Help Marking up content using RDFa RDFa is a way to label content to describe a specific type of information, such as a restaurant review, an event, a person, or a product listing. These information types are called entities or items. Each entity has a number of properties. For example, a Person has the properties name, address, job title, company, and email address. In general, RDFa uses simple attributes in XHTML tags (often <span> or <div>) to assign brief and descriptive names to entities and properties. <div> My name is Bob Smith but people call me Smithy. Here is the same HTML marked up with RDFa. <div xmlns:v=" typeof="v:Person"> My name is <span property="v:name">Bob Smith</span>, but people call me <span property="v:nickname">Smithy</span>. Here's how the sample works. The example begins with a namespace declaration using xmlns. Nested items The example above shows contact information about Bob Smith. For more examples, see Nested items.
