Request for Comments 5955 💌 The application/timestamped-data Media Type

okay bestie, this one is RFC 5955 🎀. It's by A. Santoni from Actalis S.p.A., published August 2010, and it's Informational 🌸, so it's not an Internet Standards Track thing. It updates RFC 5544 and doesn't list anything it obsoletes. The ISSN is 2070-1721 🦋.

Abstract ✨

this doc defines a brand new media type for TimeStampedData envelopes, the stuff described in RFC 5544 💅

Status of This Memo 🫶

this one is NOT an Internet Standards Track spec. it's published just for info purposes 💖

it's still a product of the IETF, so it has consensus from the IETF community, got public review, and the IESG approved it for publishing. but not every IESG approved doc is a candidate for any level of Internet Standard, so check Section 2 of RFC 5741 if you're curious 🧚

1. Introduction ✨

okay so this is the part where the doc introduces the new media type for TimeStampedData envelopes 🦋. a TimeStampedData envelope (described in [RFC5544]) binds a file to one or more time-stamp tokens that were obtained for that file. RFC 5544 didn't come with a media type registration, and that's the gap this doc fills. it makes the thing way more shareable, and honestly that's the whole point 🫶

2. Registration 📝

here's the official registration form. I'm keeping it exactly as is so nothing gets lost in translation 💅

   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): .tsd
      Macintosh file type code(s):

   Person & email address to contact for further information:

      Adriano Santoni
      <adriano.santoni@actalis.it>

   Intended usage: COMMON

   Restrictions on usage: none

   Author:

      Adriano Santoni
      <adriano.santoni@actalis.it>

   Change controller: the IESG

so the big picture is: any app that swaps TimeStampedData envelopes over a MIME-based transport (and maybe processes them, directly or through external handlers or viewers) can use this. think digital signature apps, archival systems, email clients, web browsers, all of that 🌸 the file extension is .tsd, and the change controller is the IESG 👑

3. Security Considerations 🔒

this is the serious bit, bestie 😭. the security considerations of [RFC5544] apply here, and this doc doesn't add any new ones. so go read RFC 5544's security section 🫣

4. IANA Considerations 🧚

Section 2 of this doc registers one media subtype, which is application/timestamped-data 💖

5. Normative References 📚

   [RFC5544]  Santoni, A., "Syntax for Binding Documents with Time-
              Stamps", RFC 5544, February 2010.
