Schema.org — Google, Microsoft and Yahoo! Agree On Markup Vocabulary
aabelro writes "Google, Microsoft and Yahoo! have decided to propose a common markup vocabulary, Schema.org, based on the Microdata format, simplifying the job of webmasters who want to give meaning to their web pages' content."
Manu Sporny, chair of the W3C group that created RDFa, added his (personal) dissenting opinion about Schema, calling it a 'false choice,' and saying, "The entire Web community should decide which features should be supported – not just Microsoft or Google or Yahoo."
One of the reasons why Google was able to tromp AltaVista was that AltaVista's search was based completley on the MetaData tag of the html page, and Google ignored the MetaData tag. The reason why? Website administrator were putting false information into the MetaData tag in hopes of generating more web crawler search hits. Google decided to go off of what was actually being presetned on the page, and we all found that to be more useful.
The proposal is itself breaking html. This time, Google and Yahoo are in with the "extending". The vague promise of better search positions will drive web developers to completely muck up their html output. There is no reason not to re-use the Dublin Core.
