slash vs hash

[VladimirAlexiev]

• I think that http://www.example.org/# should be corrected to use slash or hash, but not both. Slash is preferred for collections of individuals, whereas hash can only be used for ontologies of relatively few terms.
• In addition, https://w3c.github.io/N3/spec/#relative-iri-example has a mistake: I think it would result in ## in resolved IRIs, which is invalid.

Any reference for that statistics? See https://www.w3.org/wiki/HashVsSlash

It's not quite that "hash can only be used for ontologies of relatively few terms" as that dereferencing hash-based URIs that identify fragments in large resources (ontologies or otherwise) can be difficult and is always inefficient use of network infrastructure, relative to slash-based URIs that dereference to the entirety of a small resource.

In other words, I would say that hash are preferred only for resources containing relatively few fragments, including ontologies of relatively few terms.
