Does any of you own an online store? do you want to have a better semantic way to list your products?
So there is a need for a new Microformat.
I suggest to establish the hStore a new Microformat for an online store that will create a more semantic way to put the data in the store pages.
so what type of entities do we have in a store?
the lowest one is a Product. There is a brand, price, catalog number and specification to each product. The specifications can be arbitrary and are not standardized.
the Product is associated to Categories.
The categories can be associated into other categories so we can reach cascading categories.
what i am suggesting is something like this

I think that this way of setting up content will enable bots to get the information off e-shops and will make the likes of shopping.com and pricegrabber.com fetch data easily out of the web.
This might enable shops to make descriptive RSS feeds that enable consumers to register to a category of a store and receive all the products of that category in a fairly ordered way.
Now i am going to post this to the review of the Microformat org.
