Hi Leigh,

Thanks for your feedback.

rdfs:seeAlso is defined as a property that "specifies a resource that 
might provide additional information about the subject resource."

So I would say using it to link from a pure data element (e.g. a price 
specification node, a warranty promise, a product, or an offer) to the 
Web page that describes all of them in one page is in compliance with 
the RDFS spec. (Note that this also allows pointers from any such 
element to hash URIs in a human-readable document - with that, users 
could directly jump e.g. to the warranty section of the page.)

Your suggestion of using

http://xmlns.com/foaf/spec/#term_isPrimaryTopicOf

instead is a viable option, but I decided against it as the default 
property for two reasons:

1. First, I did not want to force people to import and use foaf only for 
this very basic link, in particular as long as a suitable property from 
the core RDFS vocabulary is available.

2. The status of this property is "testing" only.

But is perfectly fine for anybody to attach additional

term_isPrimaryTopicOf

properties to any conceptual element in GoodRelations data.
