Re: RDFa and Web Directions North 2009

Ian,

In [1] you asked, quite rightly, for 'problem statements' re RDFa. I've
pointed out two (IMHO important) ones at [1] which you *might* have
overlooked. I'd be happy to learn from you if you think these are
'acceptable':

1. Service and product provider can't include the meaning of the things they
publish in HTML. For example, how do you find out where the price of a book
is located in, say, a page from Amazon? Now, people that want to use this
data are forced to perform *screen scraping*, that is, there is a need for
publisher-push rather than consumer-pull semantics.

2. People doing data mash-ups need to learn a plethora of APIs/formats while
all they would likely want is *one data model* + and a bunch of vocabularies
covering the domain.

Cheers,
      Michael
