An 'info' URI with namespace 'bnf' takes the form:
info:bnf/<bnf-context>/<sub-context>
bnf-context
bnf-context = ALPHA *(ALPHA / DIGIT )
i.e. alphanumeric with leading alphabetic character.
Values of <bnf-context> correspond to naming authorities
assigned by the national library of France and registered at
http://bibnum.bnf.fr/identifiants/bnFInfoURI.html.
sub-context
sub-context = sub-context-component *("/" sub-context-component) ["#" component]
sub-context-component
sub-context-component = pchar *(pchar)
The value of <sub-context-component> is an alphabetic string assigned
by the national library of France and corresponding to the
name of a specific data dictionary.
component
component = pchar *(pchar)
The value of <component> is an alphabetic string assigned
by the national library of France and corresponding to the
name of an element inside a specific data dictionary.
All data dictionaries are declared in the national library
of France preservation system documentation. When
applicable, they are published at http://bibnum.bnf.fr.
Data dictionaries are expressed using a human readable
format and can also be formalized according to a machine
readable format such as XML schema, RDFS, OWL.
pchar (and others)
pchar is as defined in RFC 3986, that is:
pchar = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded = "%" HEXDIG HEXDIG
sub-delims = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "="
ALPHA, DIGIT, AND HEXDIG are as defined in RFC 2234: upper
or lower case alphabetic (A-Z / a-z), decimal digit (0-9),
and hexadecimal digit (DIGIT / "A" / "B" / "C" / "D" / "E" /
"F") respectively.
Percent Encoded Characters
Percent Encoded Characters are used in the rare cases where
non US-ASCII characters appears in the URI.

All identifiers in the info:bnf namespace are case-sensitive.
info:bnf/spar/structure#set
info:bnf/spar/representation#thumbnail
info:bnf/rights/eventType#birth
The info:bnf is primarily used to assign URIs to classes
and properties in data dictionaries that are intended to be
expressed in RDF.
These URIs correspond to abstract concepts and they don't
need to be actionable or to dereference a resource. The BnF
is using another persistent identifier scheme (ARK) for
resources that need to be dereferenced such as digital
objects, web documents, etc.
The info URIs are meant to be easily readable for ease of
use in the system (for instance, to construct a RDF
ontology or to query it with SPARQL) so they are composed
with semantic elements rather than opaque strings.
