Michael, I had a look at some of the examples. Noteworthy is the apparent lack of any product ontology. Martin's example example is for a camera with housing. An obvious way to model this is as a bundle with two things: one of type Video Camera and one off type UnderWaterHousing. There is nothing of this sort. Rather, this and perhaps all 900,000 items are of type: Product. In other words, there is no semantics at all for the products, no types, no features, no constraints, nothing. Have I missed something? If this is true, the question is why. Possibilities include: - *Expedience**: * It is conceptually trivial to convert the catalog to RDFa this way. - *First things first*: it was just a first step, more semantics is on the way... - *Lack of perceived value: *Does it cost too much for what value there may be? I wonder what the value is for this first step. I wonder whether there are plans for adding semantics to the products themselves. Any thoughts?
