and Linked data usage growth

Curious to know how the Semantic Community welcomes this announcement
How will this announce from the big 3 (goole, yahoo and bing) affect the growth of Linked data vocabularies ?

Im' thinking of GoodRelations for example : If you look at LocalBusiness on, there's no alignment with GR or any other known vocabulary. This not Linked data anymore, it's Semantic SEO only targeted to search engines.

Does that mean they're forcing everybody to use a new vocabulary and cutting the link with previous works ? (anticipating that if microdata is the new vocab that matters, other vendors will only bother to use this one and not RDF vocabularies)

I think it sucks for people who write Movies.

I think it sucks for people involved in PoliticalEvents.

I think it sucks for people who own GiftShops, SexShops and WomensClothingStores (but not for MensClothingStores for some reason).

I think it sucks for people who own such shops and want to specify the time they close for lunch.

I think it sucks for people who live or work in Towns or Villages.

I think it sucks for Users like Signified.

...and besides proposing a centralised, closed schema for the entire Web (and not doing a particularly good job) I think it sucks for a couple of other reasons...

...but if it takes off, its shortcomings are our opportunity, as long as we look at those problems in real terms, propose real solutions, and drop our sense of entitlement...

...and if it leads to some more structured data appearing on the Web, (and although it's not the best possible outcome) I can't see how that's a bad thing, RDFa or not.

I think is just with different clothes. The big three are trying to revive microformats by agreeing on common vocabularies.The reason RDFa was created is to address the lack of scalability of the microformats. Every new microformat requires a new parser to be written. This is a sysiphian effort ! RDFa requires a single parser and can leverage any mature ontologies. It would have been better that big three agree on the ontologies to use such as FOAF, Good Relations, SIOC. Search Monkey from Yahoo was close to this solution. Seems we are going 5 years backward. Fail !! Great ideas are not always coming from big companies. SOAP and all web services movement are very limited success. Simpler approach based on REST succeeded. I do not anticipate any wide adoption of

I like the move, since it may very well bring more structure to the web that people like us can extract and manipulate. It may've been nice to have seen RDFa, but I'd rather see more strucured data in a less expressive format than less structured data in a more expressive format (assuming that RDFa is unattractive to many web devs).

I'm also a bit bothered by it. But, seems I'm not the only one:

Some additional reading:

I suspect the reason that doesn't support RDFa is a political one and is easy to see if you read between the linesgarbage in their FAQ "Why microdata? Why not RDFa or microformats?". It says: "Google and Yahoo! have in the past supported both microformats and RDFa". So all three support microformats and two support RDFa.

See my answer in the related thread on the swig mailing list ;)

Can anyone name a few sites which have "LocalBusiness" data for their own business address? I can't find any, and need some for test purposes. Thanks.
