(last updated 2007-06-18) MIME media type name : application MIME subtype name : Vendor Tree (grandfathered name) - rtf Required parameters : None Optional parameters : None Note: RTF specifies its own character set internally for its text data, thus having a charset parameter would be redundant. Encoding considerations : binary This media type may require encoding on transports not capable of handling binary data. Prior to version 1.5 textual content in RTF was 7bit only. 1.5 changed this to allow unencoded 8bit characters. However, since RTF allows inclusion of binary data in elements, binary encoding may have to be used for object of type application/rtf. Security considerations : RTF content consists of unformatted text and control words. Executable content is not allowed. RTF provides no integrity or confidentiality services internally so external signature and encryption services must be used to protect sensitive content. RTF supports references to external files and other objects. Care should be taken when resolving such references in order not to violate security policies. Interoperability considerations : Published specification : RTF version 1.6: http://msdn2.microsoft.com/en-us/library/aa140277(office.10).aspx RTF version 1.5: http://www.biblioscape.com/rtf15_spec.htm Applications which use this media type : Many applications are capable of reading and writing RTF objects.
