Abstract
Abstract
A system for Uniform Resource Names (URNs) must be capable of supporting new naming systems. As an example of proposing a new namespace, this document proposes the "ietf" namespace. This namespace consists of the RFC family of documents (RFCs, STDs, FYIs, and BCPs) developed by the IETF and published by the RFC Editor, the minutes of working groups (WG) and birds of a feather (BOF) meetings that occur during IETF conferences, and the Internet Drafts published by the Internet Drafts Editor. Both the current URN framework and URN syntax support this namespace.

The identifier has the following ABNF [2] specification:
NSS = rfc-nss / fyi-nss / std-nss / bcp-nss /
draft-nss / mtg-nss / other-nss
NSS = rfc-nss / fyi-nss / std-nss / bcp-nss / draft-nss / mtg-nss / other-nss

fyi-nss = "fyi:" 1*DIGIT
std-nss = "std:" 1*DIGIT
bcp-nss = "bcp:" 1*DIGIT
draft-nss = "id:" string
mtg-nss = "mtg:" string

string = 1*(DIGIT / ALPHA / "-")
If the IESG (or it successor) adds a new document series,
this ABNF specification will need to be updated. Further,
if a working group or BOF is created that used characters
outside the range of this ABNF specification, this
specification will need to be updated. Any system intended
to resolve names for this namespace should be written with
the awareness that this could occur at any time.

Identifier uniqueness considerations:
Identifier uniqueness considerations:
Because the rfc-editor assigns the RFC number uniquely these
URNs are unique. Since the mapping between RFCs and other
rfc-editor document series (STDs, FYIs or BCPs) is not
necessarily one-to-one, uniqueness of STDs, FYIs and BCPs
are defined based on the document mappings maintained by the
RFC Editor (the index files "rfc-index.txt", "fyi-
index.txt", "bcp-index.txt", "std-index.txt") are defined to
be the definitive statement of the assignment of RFC Family
URNs in this namespace. The meeting minutes portion of the
namespace is guaranteed unique because the URN includes the
sequence number of the IETF conference. The document
mapping maintained by the Internet Drafts editor ("1id-
abstracts.txt") is defined as the definitive statement of
the assignment of URNs for the internet draft portion of
this namespace.

Identifier persistence considerations:
Identifier persistence considerations:
Persistence of the URNs of this namespace is independent of
the mutability of the underlying documents. A URN once
assigned will never be reassigned to a different resource;
the assignment is persistent and immutable. Immutability of
RFCs, STDs, FYIs and BCPs is at the discretion of the RFC
Editor. They may be composites of one or more RFCs and the
set of RFCs that includes 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 occurs in three ways.
The first is through publication of a new RFC, FYI, STD or
BCP is by the RFC Editor. This new document will have a new
series number and will therefore define a new URN. The
document mappings maintained by the RFC Editor (the index
files "rfc-index.txt", "fyi-index.txt", "bcp-index.txt" and
"std-index.txt") are defined to be the definitive statement
of the assignment of RFC Family URNs in this namespace.

The second way a URN is assigned is through the filing of
meeting minutes by a working group or birds of a feather as
part of an IETF conference. The list of minutes maintained
by the IETF for each working group and conference in the
subtree pointed at by the URL ftp://ietf.org/ietf/ is
considered the definitive assignment of URNs for working

group or birds of a feather minutes.
The third way a URN is assigned is through the publication
of a new internet-draft by the Internet Draft Editor. This
draft will have a distinct name (and version number) and
therefore defined a new URN. The document mapping
maintained by the Internet Drafts editor ("1id-
abstracts.txt") is defined as the definitive statement of
the assignment of URNs for this portion of the namespace.

4. Security Considerations
4. Security Considerations
Because this namespace defines no additional reserved characters, it does not add any security considerations beyond those inherent from the existence of the reserved characters from [1]. Further, none of the reserved characters from [1] are used in the definition of the NSS. This means that resolvers for this namespace may be considered "secure" in the sense that any escaping of characters in the NSS MUST result in the resolver indicating that the URN has incorrect syntax.
