OpenGraph or Schema.org?

Question

Just wondering whether you guys out there are favouring the OpenGraph protocol following markup like:

Answer 1

RDFa og serves as uniform way to recognize content better by REST for consideration when embedding within containers not predicted at the time of creation. If the container is predetermined as search results, then schema.org microdata is well-understood by search bots. With og presentation is responsibility of container publisher & such quality freedom might improvise search ranking, while schema.org will improvise search result comprehensibility in the context of content creator's intent. The vocabularies usually are ignored when used with the competing semantic markup technique so best to use microdata with schema.org only and og with RDFa only. Both microdata and RDFa can coexist in same document.
