To: ietf-types@iana.org Subject: Registration of media type application/urc-uisocketdesc+xml Type name: application Subtype name: urc-uisocketdesc+xml Required parameters: none Optional parameters: charset parameter (see definition of this parameter for application/xml, RFC 3023) Encoding considerations: Same as encoding considerations of application/xml as specified in RFC 3023. Security considerations: All of the security considerations described in section 10 of RFC 3023. The inclusion of XPath 2.0 fragments is deemed to not increase the security risk, for the following reasons: (1) XPath 2.0 is purposed for processing of values rather than modification of values. (2) The use of XPath 2.0 in User Interface Socket Descriptions is restricted in that there is no Data Model (that could potentially be modified). (3) The scope of XPath 2.0 constructs is limited to the Socket Description document which does not contain private data. (The Socket Description describes the structure of a User Interface Socket, but does not contain the runtime data.) The general utility of this media type to the Internet community is in the area of remote user interfaces for devices and services that use Internet-based technologies, in particular the Universal Remote Console (URC) technology (ISO/IEC 24752). A device/service that exposes a User Interface Socket Description, as defined by ISO/IEC 24752-2, can be remotely controlled by pluggable user interfaces conforming to this standard. The separation of device/service functionality and user interface allows for an open user interface platform, thus facilitating personalized user interfaces and user interfaces tailored for specific user groups, including users with disabilities. Interoperability considerations: Same as interoperability considerations of text/xml as specified in RFC 3023. Published specification: ISO/IEC 24752-2:2008 Applications that use this media type: Universal Remote Console clients, i.e. software and hardware for the purpose of remote control of devices and services. Additional information: Magic number(s): Same as magic number(s) of text/xml as specified in RFC 3023. File extension(s): .uis Macintosh file type code(s): Person & email address to contact for further information: Gottfried Zimmermann Intended usage: COMMON Restrictions on usage: none Author: ISO/IEC 24752-2 is an international standard by ISO/IEC JTC1 SC35, and was edited by: Gottfried Zimmermann Change controller: ISO/IEC JTC1 SC35 and its working group 8 have change control over ISO/IEC 24752-2.
