1. Introduction 1. Introduction
This document proposes the "ietf" namespace, which consists of the This document proposes the "ietf" namespace, which consists of the
RFC family of documents (RFCs, STDs, FYIs, and BCPs) developed by the RFC family of documents (RFCs, STDs, FYIs, and BCPs) developed by the
IETF and published by the RFC editor and the minutes of working IETF and published by the RFC editor and the minutes of working
groups (WG) and birds of a feather (BOF) meetings that occur during groups (WG) and birds of a feather (BOF) meetings that occur during
IETF conferences. IETF conferences.
The namespace specification is for a formal namespace. The namespace specification is for a formal namespace.

Declaration of structure: Declaration of structure:
The identifier has the following ABNF [2] specification: The identifier has the following ABNF [2] specification:
NSS = (family ":" number) / ("mtg-" number "-" wgbofname) NSS = (family ":" number) / ("mtg-" number "-" wgbofname)
family = "rfc" / "std" / "fyi" / "bcp" family = "rfc" / "std" / "fyi" / "bcp"
number = 1*DIGIT number = 1*DIGIT
wgbofname = 1*LETDIGIT wgbofname = 1*LETDIGIT
LETDIGIT = DIGIT / %x41..%x5a / %x61..%x7a LETDIGIT = DIGIT / %x41-%x5a / %x61-%x7a
DIGIT = %x30..%x39 DIGIT = %x30-%x39
If the IESG (or it successor) adds a new document If the IESG (or it successor) adds a new document
series, this ABNF specification will need to be series, this ABNF specification will need to be
updated. Further, If a working group or BOF is updated. Further, if a working group or BOF is
created that used characters outside the range of this created that used characters outside the range of this
ABNF specification, this specification will need to be ABNF specification, this specification will need to be
updated. Any system intended to resolve names for updated. Any system intended to resolve names for
this namespace should be written with the awareness this namespace should be written with the awareness
that this could occur at any time. that this could occur at any time.
Identifier uniqueness considerations: Identifier uniqueness considerations:
Because the rfc-editor assigns the RFC number uniquely Because the rfc-editor assigns the RFC number uniquely
these URNs are unique. Since the mapping between RFCs these URNs are unique. Since the mapping between RFCs
and other rfc-editor docuent series (STDs, FYIs or and other rfc-editor document series (STDs, FYIs or
BCPs) is not necessarily one-to-one, uniqueness of BCPs) is not necessarily one-to-one, uniqueness of
STDs, FYIs and BCPs are defined based on the document STDs, FYIs and BCPs are defined based on the document
mappings maintained by the RFC Editor (the index files mappings maintained by the RFC Editor (the index files
"rfc-index.txt", "fyi-index.txt", "bcp-index.txt" and "rfc-index.txt", "fyi-index.txt", "bcp-index.txt" and
"std-index.txt") are defined to be the definitive "std-index.txt") are defined to be the definitive
statement of the assignment of RFC Family URNs in this statement of the assignment of RFC Family URNs in this
namespace. The meeting minutes portion of the namespace. The meeting minutes portion of the
namespace is guaranteed unique because the URN namespace is guaranteed unique because the URN
includes the sequence number of the IETF conference. includes the sequence number of the IETF conference.
Identifier persistence considerations: Identifier persistence considerations:
Persistence of the URNs of this namespace is dependent Persistence of the URNs of this namespace is
on the persistence of the underlying documents. The independent of the mutability of the underlying
fundamental difference between RFCs on one hand and documents. A URN once assigned will never be
STDs, FYIs, or BCPs on the other is that only RFCs are reassigned to a different resource; the assignment is
real, even persistent, documents while the others are persistent and immutable. Distinct from this, the
just names for sets of one or more RFCs which may resources identified as RFCs are immutable, whereas
change over time. the other sorts of documents, STDs, FYIs, and BCPs are
not. They may be composites of one or more RFCs and
the set of RFCs that comprise them may change with
time. It is important to note that this mutability of
some resources is independent of the immutability of
URN assignment to a resource.
Process of identifier assignment: Process of identifier assignment:
Assignment of URNs from this namespace occur in two Assignment of URNs from this namespace occurs in two
ways. The first is when a new RFC, FYI, STD or BCP is ways. The first is when a new RFC, FYI, STD or BCP is
passed by the IESG and published by the RFC passed by the IESG and published by the RFC
Editor. This new document will have a new series Editor. This new document will have a new series
number and will therefore define a new URN. The number and will therefore define a new URN. The
document mappings maintained by the RFC Editor (the document mappings maintained by the RFC Editor (the
index files "rfc-index.txt", "fyi-index.txt", index files "rfc-index.txt", "fyi-index.txt",
"bcp-index.txt" and "std-index.txt") are defined to be "bcp-index.txt" and "std-index.txt") are defined to be
the definitive statement of the assignment of RFC the definitive statement of the assignment of RFC
Family URNs in this namespace. Family URNs in this namespace.
