What value could you expect from the use of schema.org metadata?

[andrewwolf]

Google , Yahoo and Bing have now teamed up to develop unified Meta data standards for all types of content.

I personally see this as the next step to larger world-wide knowledge availability.

Why is this a big deal?
If everything comes together, and every page had perfect markup, the answers to users questions could be answered and validated against the information found on every website that had that answer.

Example: Who is the author of "The catcher in the Rye"

11345 Websites Result : J. D. Salinger
301: Websites Resulted : Jake Salinger

Best Result: J.D. Salinger  -> Contact J.D Salinger -> Bio etc.

Information would become the link , user's navigation intent becoming the Anchors.

Here is the URL of the different types of metadata schema's found on google's new schema.org

http://schema.org/docs/schemas.html

• Creative works: CreativeWork, Book, Movie, MusicRecording, Recipe, TVSeries ...
• Embedded non-text objects: AudioObject, ImageObject, VideoObject
• Event
• Organization
• Person
• Place, LocalBusiness, Restaurant ...
• Product, Offer, AggregateOffer
• Review, AggregateRating

What are the benefits of the different categories of metadata being used?

Can anyone site specific case studies done on the enhanced SERP results shown as a result of this metadata?

I haven't seen a case study although everyone has been showing this with Google Recipes.

The one issue that has come up is that by making it easier to display info in the SERPs there is a possibility that people may never click-through. For example, if you are searching for movie times or the length of a music recording or the time of event you can get that information on the SERPs and never make it to the page.

So GYB want us to neatly package our info for them but then they benefit because people search for something else rather than spending time on our sites.
