A new URL scheme, "vemmi" is defined. It allows VEMMI client software and VEMMI terminals to connect to multimedia interactive services compliant to the VEMMI standard (Enhanced Man-Machine Interface for Videotex and Multimedia/Hypermedia Information Retrieval Services), sometimes abbreviated as "VErsatile MultiMedia Interface".

VEMMI URL Specification
Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state

A new URL scheme, "vemmi" is defined. It allows VEMMI client software
and VEMMI terminals to connect to multimedia interactive services
compliant to the VEMMI standard (Enhanced Man-Machine Interface for
Videotex and Multimedia/Hypermedia Information Retrieval Services),
sometimes abbreviated as "VErsatile MultiMedia Interface".
VEMMI is a new international standard for on-line multimedia
services, that is both an ITU-T (International Telecommunications
Union, ex. CCITT) International Standard (T.107)  and an
European Standard (ETSI European Telecommunications Standard
Institute) standard (ETS 300 382 , obsoleted by ETS 300 709 ).
VEMMI could be described as an on-line multimedia protocol describing
both the man-machine interface and the client/server exchange
protocol. VEMMI operates usually on a single continuous session
between a client and a host and supports an object-oriented, event-
driven, client/server oriented and platform independent multimedia
interface. The well-known tcp port number 575 has been assigned by
IANA to the VEMMI protocol .
A description of the VEMMI standard along with its last approved
version is publicly available on the Web: see the URL
http://www.etsi.fr/ecs/projects/vemmi/vemmi.htm). A presentation of
VEMMI can be found on http://www.mctel.fr/VEMMI/vemmien_intro.html
2) VEMMI URL scheme utility and operability:
- VEMMI service selection: A VEMMI multimedia server will listen on
its VEMMI well-known port for incoming connections. The server
could of course be engaged in many simultaneous connections, and
after a connection is established, the terminal must be able to
select the desired VEMMI application, as a same system may host
different VEMMI applications.
The best mechanism to fully describe the VEMMI service to activate
is the URL mechanism.
- Reporting user action to a remote server: The VEMMI protocol
establishes a continuous TCP/IP link between the terminal and the
server during the whole user session. During a ...
