INTERNET DRAFT The tn3270 URI scheme December 12, 2010
1. Introduction
The tn3270 URI scheme was first mentioned in RFC 1738 [RFC1738].
Following the creation of the URI scheme registries per RFC 4395
[RFC4395], it was added to the "Provisional" registry. However there
are no clear and acceptable specifications so far for this scheme.
The generic syntax of URIs is described in RFC 3986 [RFC3986]. URI
registering procedures are defined in RFC 4395 [RFC4395].
This document gives a specification of syntax, semantics and use of
tn3270 URI scheme.
2. Scheme Definition
The tn3270 URI scheme is used to access services that are provided
via TN3270 Telnet Service - Interactive 3270 emulation session (see
RFC 1041 [RFC1041] and RFC 2355 [RFC2355] for details). TN3270
service practices are defined in RFC 1576 [RFC1576]. In fact this is
Telnet service with special data transfer mode so the form of URI is
similar to that of telnet one.
Note: This document does not specify the TN3270 service itself, but
only URI scheme for it.
The tn3270 URI takes the following form (given in ABNF, as described
in RFC 5234 [RFC5234]):
tn3270_uri = "tn3270:" "//" authority ["/"]
authority = <as defined in RFC 3986 [RFC3986]>
The final character "/" can be omitted.

3. Security Considerations
Generic security considerations for the usage of URIs are discussed
in Section 7 of [RFC3986].
Many security consideration for telnet URI scheme defined in Section
3 of RFC 4248 [RFC4248] concern tn3270 one as well.
4. IANA Considerations
IANA is asked to update the registration of tn3270 URI scheme using
the following registration template:
URI scheme name: tn3270
Status: Provisional
URI scheme syntax: Section 2 of RFC xxxx
URI scheme semantics: Section 2 of RFC xxxx
URI scheme encoding considerations: generic encoding considerations
for URI schemes, defined in Section 2 of [RFC3986], concern tn3270
one as well. Non-ASCII characters are to be treated as defined in RFC
3987 [RFC3987]
Protocols that use the scheme: Telnet TN3270 mode (see RFC 1041
[RFC1041] and RFC 2355 [RFC2355] for details)
Security considerations: Section 3 of RFC xxxx
