I guess we'll never know!
The text was:
[
By defining a WebID to be a hash-based we put a lot of semantics into a
single character where the most important parts are that an entity is
described in a standardized way. Two identical => descriptions <= of a real
world entity are treated differently if webid.toString().indexOf("#") is -1
or > 0. That what's interesting for the verifier is not the uri-string, but
the description of an entity. In other words a verifier must judge the
graph not (only) by the triples it contains, but also by a certain
character in the subject's uri.
]
Once again, we ALWAYS introspect on a string to determine next steps. It
may be one character but the : after the http is also a case of
introspection, based on the URI spec. HTTP has its regex too for defining
things such as domain, port and fragment. Yes the triples in a document
are important but so is the URL.
