[whatwg] RDFa statement consistency (was: RDFa Basics Video (8 minutes))

[Kristof Zelechovski]

I think RDFa has already happened: you know what it is and how to use it.
You can embed it in XHTML.  Why is having it in HTML necessary for creating
statistical models?

It is understood that there may be data that is corrupt and that is
okay. There is an area of semantic web development that deals with the
concept of provenance and validation. You can even apply statistical
models to catch logical inconsistencies, but those models need a core
set of semantic information to be of any use. RDFa must happen before
any sort of statistical model can be created for checking logical
consistency between HTML text and semantic data.
