(Registered 16 December 2004) Name : Stefan Eilemann Email : [email protected] MIME media type name : Text MIME subtype name : Vendor Tree - vnd.esmertec.theme-descriptor Required parameters : None Optional parameters : charset The esmertec theme descriptor file conforms to the usage of the optional charset parameter for text/plain in rfc2046. Since the file contains text used by Java applications it is expected that most theme descriptor files will be delivered as UTF-8. The default charset is UTF-8. Encoding considerations : 8bit This media type may require encoding on transports not capable of handling 8 bit text. Security considerations : The theme descriptor contains attribute information used by MIDP rendering software. The descriptor file references a downloadable Jar file. The resources in the jar file configure the look and feel of MIDP applications. Although the jar file does not contain executable code, a bogus descriptor file could direct a client to download a potentially harmful theme description file. Alternately, the request to get the theme description could be intercepted and a bogus file substituted. For this reason a network operator might require the descriptor file and associated Jar file to be delivered from the same source and delivered over a secure network connection. Interoperability considerations : None Published specification : None Applications which use this media : Esmertec's J2ME application management software which runs on mobile devices that are enabled with a Java Virtual Machine(JVM) execution environment. The theme descriptor provides the information needed to download and install a theme. Additional information : 1. Magic number(s) : none 2. File extension(s) : jtd 3. Macintosh file type code : none 4. Object Identifiers: none Person to contact for further information : 1. Name : Stefan Eilemann 2.
