Not quite. The semantic web focuses on normalizing all data into a single ontology, which is great for computers but does nothing to standardize the user interface side of accessing data. Needless to say, it also hasn't gotten far.

That's a good point, and I completely agree that it hasn't gotten far.

I do think that if it were to be embraced as a more common standard on websites, building a more standard UI on top should be _relatively_ simple as each websites underlying data would _hopefully_ be structured the same.
