Website would need an identity / payment ID?  Perhaps the ‘offer’ also needs an ID.  

RE: SEMANTIC ADVERTISING CONCEPT
So; the brainchild (in concept) is: i create an advertising offer with predicates.  i load onto my WebServer, where that offer becomes identifiable by ‘agents’ that can then make an agreement and serve it up.  somehow usage is tracked, et.al. triggering settlement, etc.

The problem Andrew Mackie led me into; related to this concept of being able to decentralise advertising offers.  So, simple ‘agents’ could carry out tasks in a semantic (decentralised) fashion.

I’m thinking now; this has more to do with some sort of checksum credential; some way of declaring a file is what it’s publisher intended it to be, for web-documents.  

ie: 
SCRIPT = same script, will carry out function as intended.
FOAF = as defined by original author.

Yes. Again; legal instrument thing - trying to ensure it’s you selling your bike, not ya sister, brother or the kids at school who took it home.

per above: NB: i’m talking about being able to ‘semantically’ discover these documents that may be stored in peoples individual ‘cloud storage accounts’. (meaning the site doing presentation may be different to the site where these documents are created / stored)

its’ not.  more of a technical marketing esk. comment.  perhaps still useful, agree with your determination for spec. definition purposes.

Smart contract requires the legal instrument test. therein; credentials would be used, to support the payments function?

yes.  signature or ‘legal instrument’ test.
