There are 3 scopes, from the largest to the most specific and in that order: node, requestor, thread.

Node level pages are typically used where information are applicable to every application on the specific node of the PRPC server. Example: Organisation's Name

Requestor level pages are typically used where information are applicable to every application that the requestor have access to. Example: Requestor's Name

Thread level pages are typically used where information are applicable only to that specific thread, i.e. application. Example: Product's Name

Now, granted if the product list is used between multiple application accessible by a requestor, it can be at the Requestor scope. Taking it further, if the product list is used Organisation-wide, it can be at the Node level!

However, this question does not make these assumptions and therefore the answer is as such.
