Yes, but the URI/URL address space isn't as important as the actual *denotation* an *indirection* functionality delivered by generic Linked Data URIs. This is why (of late) I've been publishing notes about sample Turtle document [1] that demonstrate how Linked Data can be deployed in a manner that showcases the power of entity names over entity description document addresses, without burdening document publishers with any of the following: 1. domain ownership 2. dns server access with admin privileges 3. web server ownership 4. web server access with admin privileges 5. URI style choices for entity name/ description document address disambiguation. > > JSON-LD does not mention http: schemes and is not limited to them. > http: is highly desirable but not necessary. But I am talking about the RDF side of things here; specifically about the *inaccurate claim* that any RDF document is a Linked Data document.
