RFC 5955              application/timestamped-data           August 2010Table of Contents1. Introduction...................................................22. Registration...................................................23. Security Considerations........................................34. IANA Considerations............................................35. Normative References...........................................31.  Introduction   This document defines a new media type for TimeStampedData envelopes.   A TimeStampedData envelope, described in [RFC5544], binds a file with   one or more time-stamp tokens obtained for that file.  A media type   registration, lacking in [RFC5544], enhances shareability.2.  Registration   Type name: application   Subtype name: timestamped-data   Required parameters: none   Optional parameters: none   Encoding considerations: binary   Security considerations:      See the Security Considerations in the published specification.   Interoperability considerations: none   Published specification:RFC 5544   Applications which use this media type:      Any application that exchanges TimeStampedData envelopes over a      MIME-based transport and possibly processes them, either directly      or via external handlers or viewers.  Such applications may be,      for instance, digital signature applications, archival systems,      email clients, web browsers, etc.   Additional information:      Magic number(s):      File extension(s): .tsdSantoni                       Informational                     [Page 2]
