Thanks !

I think you can think of this as a way for an AI systems to assemble the data on the internet.

The point I was trying to make is that we have to lay the foundation first, which is exposing triples on web pages. Once those triples are there, there are many, many types of applications we can build based on that foundation. It is analogous to saying that the more people and pages there are on Wikipedia, the more useful that site becomes...

Thanks for the foaf:name correction - I'll make sure to make the change it in future videos.

As for the mixing semantics/syntax comment, I think practicality plays a large role in RDFa. There is benefit for keeping the machine readable and the human readable data in sync and in the same document, which is what both Microformats and RDFa does.

But in your example, the human-readable text "Jane is friends with Mac" is not in sync with the machine-readable data "#jane foaf:knows #mac". You can change the text and the data could stay. Do you call this "in sync"? Aren't you asking people to keep text and data "in sync"? Is there a way to generate the text "Jane is friends with Mac" from the data "#jane foaf:knows #mac". It's not obvious from your example.
