A new URL scheme, "vemmi" is defined. 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). [STANDARDS-TRACK]

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 and status of this protocol. Distribution of this memo is unlimited.
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 session managing VEMMI objects, the user actions are usually reported back to the server using the VEMMI user data report mechanism that is an integral part of the VEMMI protocol. However, in some case, the URL mechanism may be required to send back reports to a remote host. VEMMI is for example able to display HTML documents within a mult...
