Should I return an object wrapped by an article tag?
Spec:


  The article element represents a complete, or self-contained, composition in a document, page, application, or site and that is, in principle, independently distributable or reusable, e.g. in syndication. This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content.



Complete and self-contained? Yes - it has information about foostore which doesn't require the rest of the document to make sense.
Composition? A work of music, literature, or art? Not really. It would work better if it included a review.
One of the below:


A post? No.
An article? No.
Blog entry? No.
User-submitted content? Is it?
Interactive? No.



So probably not, as long as it isn't user-generated reviews.
