SEO reaction. I'm hesitant to either use superlatives or make predictions concerning search engine innovations (I'm the first to deride commentators that use the phrase "game changer" in almost any context), but the joint announcement by Google, Yahoo and Bing introducing schema.org is, in my opinion, pretty big news.
Schema.org at once provides a mechanism by which semantic web technologies can become a lot more mainstream, and at the same time offers the possibility of superior search visibility for search marketers that embrace this standardized, structured on-page markup.

A microdata2json Python script. +Vous Recherche Images Maps. GoodReads microdata. I’m not sure how long it has been there, but I just happened to notice that GoodReads (the popular social networking site for book lovers to share what they are reading and have read) has implemented HTML5 Microdata to make metadata for books available in the HTML of their pages.
GoodReads has chosen to use the the Book type from schema.org vocabulary, most likely because the big three search engines (Google, Bing and Yahoo) announced that they will use the metadata to enhance their search results. So web publishers are motivated to publish metadata in their pages, not because it’s the “right” thing to do, but because they want to drive traffic to their websites.

Microdata + RDF. As part of the ongoing discussion about how to reconcile RDFa and microdata (if at all), Nathan Rixham has put together a suggested Microdata RDFa Merge which brings together parts of microdata and parts of RDFa, creating a completely new set of attributes, but a parsing model that more or less follows microdata’s.
I want here to put forward another possibility to the debate. I should say that this is just some noodling on my part as a way of exploring options, not any kind of official position on the behalf of the W3C or the TAG or any other body that you might associate me with, nor even a decided position on my part. Simplifying RDFa As I’ve said before, RDFa, in my experience, is complicated not primarily because of the whole namespaces/CURIEs issue but because its processing model tries to be too clever. RDFa was designed to largely fit in with existing markup and turn it into embedded data “just” by adding a few attributes here and there. Then to provide its license: Microdata RDFa Merge - W3C Wiki. Introduction Important: this is not a specification, or even a proposal, it's just some notes from Nathan Rixham, thinking out loud, in a publicly visible and editable space.
This page focusses on taking the best elements of Microdata and RDFa and creating a simple, for now fictional, set of attributes to handle metadata needs in HTML. Is Schema.org Really a Google Land Grab? Last week the Web's three leading search companies - Google, Microsoft and Yahoo!
- announced a new structured data collaboration called Schema.org. It includes more than 100 new types of website markup for content like movies, music, organizations, TV shows, products, places and more. The stated aim of Schema.org is to "improve the display of search results, making it easier for people to find the right web pages. " However, is this collaboration routing around existing web standards, as promoted by the governing web body the World Wide Web Consortium (W3C)?

As the ‘schema guy’ at Yahoo! , I have been part of the very small core team that developed technical content for schema.org.
