RFC Format Framework
draft-flanagan-rfc-framework-08
Abstract
The canonical format for the RFC Series has been plain-text, ASCII-
encoded for several decades. After extensive community discussion
and debate, the RFC Editor will be transitioning to XML as the
canonical format, with different publication formats rendered from
that base document. These changes are intended to increase the
usability of the RFC Series by offering documents that match the
needs of a wider variety of stakeholders. With these changes,
however, comes an increase in complexity for authors, consumers, and
the publisher of RFCs. This document serves as the framework that
describes the problems being solved and summarizes the many documents
that capture the specific requirements for each aspect of the change
in format.

Internet-Draft RFC Format Framework December 2015
1. Introduction
[RFC6949], "RFC Series Format Requirements and Future Development,"
discussed the need for additional features within RFCs such as non-
ASCII characters to respect author names, more advanced artwork than
ASCII art, and documents that could display properly on a wide
variety of devices. Based on the discussions with the IETF community
as well as other communities of interest, the RFC Series Editor
decided to explore a change to the format of the Series
[XML-ANNOUNCE]. This document serves as the framework that describes
the problems being solved and summarizes the documents created to-
date that capture the specific requirements for each aspect of the
change in format.
Key changes to the publication of RFCs are highlighted, and a
transition plan that will take the Series from a plain-text, ASCII-
only format to the new formats is described [RFC-INTEREST].
This document is concerned with the production of RFCs, focusing on
the published formats. It does not address any changes to the
processes each stream uses to develop and review their submissions
(specifically, how Internet-Drafts will be developed). While I-Ds
have a similar set of issues and concerns, directly addressing those
issues for I-Ds will be discussed within each document stream.
The details described in this document are expected to change based
on experience gained in implementing the RFC production center's
toolset. Revised documents will be published capturing those changes
as the toolset is completed. Other implementers must not expect
those changes to remain backwards-compatible with the details
described this document.
2. Problem Statement
When the first RFCs were published 45 years ago, the tools to create
and read RFCs were limited. Distribution was in effect restricted to
individuals who had access to the network that became the Internet.
Today, there are nearly three billion people connected to the
Internet, and individuals from 45 countries or more regularly
attending IETF meetings over the last 5 years [ISTATS]. The Internet
is now global, and while the world has changed from when the first
RFCs were published, the Series remains critical to defining
protocols, standards, best practices, and more for this global
network that continues to grow. In order to make RFCs easily
viewable to the largest number of people possible, across a wide
array of devices, and to respect the diversity of authors and
Flanagan Expires June 11, 2016 [Page 3]
Internet-Draft RFC Format Framework December 2015
reference materials, it is time to update the tightly prescribed
format of the RFC Series.
All changes to the format of the RFC Series must consider the
requirements of a wide set of communities, over an extended length of
time. For example, existing authors and implementers, lawyers that
argue Intellectual Property Rights (IPR) cases, educators, managers,
and policy-makers that need to know what to list in potential RFPs
for their organizations, all have preferences and requirements for
their specific needs. The immediate needs of today's communities
must be balanced with the needs for long-term archival storage.
3. Terminology
The following terminology is used as described in RFC 6949:
ASCII: Coded Character Set - 7-bit American Standard Code for
Information Interchange, ANSI X3.4-1986
Canonical format: the authorized, recognized, accepted, and
archived version of the document
Metadata: information associated with a document so as to provide,
for example, definitions of its structure, or of elements within
the document such as its topic or author
Publication format: display and distribution format as it may be
read or printed after the publication process has completed
Reflowable text: text that automatically wraps to the next line in
a document as the user moves the margins of the text, either by
resizing the window or changing the font size
Revisable format: the format that will provide the information for
conversion into a Publication format; it is used or created by the
RFC Editor
Submission format: the format submitted to the RFC Editor for
editorial revision and publication
4. Overview of the Decision Making Process
Requirements, use cases, concerns, and suggestions were collected
from the communities of interest at every stage of the RFC format
update project. Input was received through the rfc-interest mailing
list, as well as in several face-to-face sessions at IETF meetings.
Regular conversations were held with the IETF, IRTF, IAB, and IAOC
chairs, and the Independent Stream Editor, to discuss high-level
Flanagan Expires June 11, 2016 [Page 4]
Internet-Draft RFC Format Framework December 2015
stream requirements. Updates regarding the status of the project
were provided to the IETF community during the IETF Technical Plenary
as well as Format BoFs or IAB sessions at IETF 84, IETF 85, IETF 88,
IETF 89, and IETF 90 [IETF84] [IETF85] [IETF88] [IETF89] [IETF90].
The first document published, RFC 6949, provided the first solid
documentation on what the requirements were for the Series and in
effect was the output from the first year of discussion on the topic
of RFC format. That RFC, as with all of the RFCs that informed the
format update work, was published as an IAB stream document, thus
following the process described in RFC 4845, "Process for Publication
of IAB RFCs" [RFC4845].
After the high-level requirements were published, the RFC Series
Editor (RSE) brought together an RFC Format Design Team to start
working out the necessary details to develop the code needed to
create new and changed formats. While the bi-weekly calls for this
team were limited to Design Team members, review of the drafts
produced by this team were done publicly through requests for
feedback on the rfc-interest mailing list. Several of the drafts
produced by the Design Team, including the XML v2 and v3 drafts and
the SVG profile drafts, were sent through an early GenART review
before starting the process to be accepted as an IAB stream draft
[GEN-ART].
While the IETF community provided the majority of input on the
process, additional outreach opportunities were sought to gain input
from an even broader audience. Informal discussions were held with
participants at several International Association of Scientific,
Technical, and Medical Publisher events, and presentations made at
technical conferences such as the TERENA Networking Conference 2014
and NORDUnet 2014 [TNC2014] [NDN2014].
In order to respond to concerns regarding responses to subpoenas and
to understand the requirements for lawyers, advice was requested from
the IETF Trust legal team regarding what format or formats would be
considered reasonable when responding to a subpoena request for an
RFC.
Given that several other standards development organizations (SDOs)
do not offer plain-text documents, and in fact may offer more than
one format for their standards, informal input was sought from them
regarding their experience with supporting one or more non-plain-text
formats for their standards.
Finally, the entire process was reviewed regularly with the RFC
Series Oversight Committee and regular updates provided to the IAB
and IESG [RSOC].
Flanagan Expires June 11, 2016 [Page 5]
Internet-Draft RFC Format Framework December 2015
Where consensus was not reached during the process, the RSE made any
necessary final decisions, as per the guidance in RFC 6635, "RFC
Editor Model (Version 2)" [RFC6635].
5. Key Changes
At the highest level, the changes being made to the RFC Format
involve breaking away from a pure-ASCII plain text and moving to a
canonical format that includes all the information required for
rendering a document into a wide variety of publication formats. The
RFC Editor will become responsible for more than just the plain-text
file and the PDF-from-text format created at time of publication;
they will be creating several different formats in order to meet the
diverse requirements of the community.
The final XML file produced by the RFC Editor will be considered the
canonical format for RFCs; it is the lowest common denominator that
holds all the information intended for an RFC. PDF/A-3 will be the
publication format offered in response to subpoenas for RFCs
published through this new process, and will be developed with an eye
towards long-term archival storage. HTML will be the focus of
providing the most flexible set of features for an RFC, including
JavaScript to provide pointers to errata and other metadata. Plain-
text will continue to be offered in order to support existing tool
chains where practicable and the individuals who prefer to read RFCs
in this format.
6. Canonical Format Documents
6.1. XML for RFCs
Key points regarding the XML format:
o The canonical format for RFCs is XML using the XML2RFC v3
vocabulary [I-D.hoffman-xml2rfc]. This file must contain all
information necessary to render a variety of formats; any question
about what was intended in the publication will be answered from
this format.
o Authors may submit drafts in XML2RFC v2 vocabulary, but the final
publication will convert that to XML2RFC v3 vocabulary.
o SVG is supported and will be embedded in the final XML file.
o There will be automatically generated identifiers for sections,
paragraphs, figures, and tables in the final XML file.
Flanagan Expires June 11, 2016 [Page 6]
Internet-Draft RFC Format Framework December 2015
o The XML file will not contain any v3 vocabulary elements or
attributes that have been marked deprecated.
o A Document Type Definition (DTD) will no longer be used. The
grammar will be defined using RelaxNG.
o The final XML file will contain, verbatim, the appropriate
boilerplate specified by RFC 5741.
o The final XML will be self-contained. For instance, all features
that reference externally-defined input will be expanded. This
includes all uses of xinclude, src attributes (such as in
<artwork> or <sourcecode> elements), include-like processing
instructions, and externally defined entities.
o The final XML will not contain comments or processing
instructions.
o The final XML will not contain src attributes for <artwork> or
<sourcecode> elements.
[I-D.iab-xml2rfcv2] Describes the xml2rfc v2 vocabulary. While in
wide use today, this vocabulary had not been formally documented. In
order to understand what needed to change in the vocabulary to allow
for a more simple experience and additional features for authors, the
current vocabulary needed to be fully described. This document, when
published, will be obsoleted by the RFC published from draft-hoffman-
xml2rfc.
[I-D.hoffman-xml2rfc] Describes the xml2rfc v3 vocabulary. The
design goals in this vocabulary were to make the vocabulary more
intuitive for authors, and to expand the features to support the
changes being made in the publication process. This draft, when
published, will obsolete the RFC published from draft-iab-xml2rfcv2.
7. Publication Format Documents
7.1. HTML
[I-D.hildebrand-html-rfc] - Describes the semantic HTML that will be
produced by the RFC Editor from the xml2rfc v3 files.
Key points regarding the HTML output:
o The HTML will not be derived from the plain-text publication
format.
Flanagan Expires June 11, 2016 [Page 7]
Internet-Draft RFC Format Framework December 2015
o The body of the document will use a subset of HTML. The documents
will include CSS for default visual presentation; it can be
overwritten by a local CSS file.
o SVG is supported and will be included in the HTML file.
o Text will be reflowable.
o JavaScript will be supported only as an additional option for
presentation of specific publication formats to provide up-to-date
links to post-publication metadata, such as errata or obsoletion.
Documents will be complete and readable when JavaScript is
disabled.
7.2. PDF
[I-D.hansen-rfc-use-of-pdf] - Describes the tags and profiles that
will be used to create the new PDF format, including both the
internal structure and the visible layout of the file. A review of
the different versions of PDF is offered, with a recommendation of
what PDF standard should apply to RFCs.
Key points regarding the PDF output:
o The PDF file will not be derived from the plain-text publication
format.
o The PDF publication format will conform to the PDF/A-3 standard
and will embed the canonical XML source.
o The PDF will look more like the HTML publication format than the
plain-text publication format.
o The PDF will include a rich set of tags and metadata within the
document
o SVG is supported and will be included in the PDF file.
7.3. Plain Text
[I-D.flanagan-plaintext] - Describes the details of the plain text
format, focusing in particular on what is changing from the existing
plain-text output.
Key points regarding the plain-text output:
o The plain-text document will no longer be the canonical version of
an RFC.
Flanagan Expires June 11, 2016 [Page 8]
Internet-Draft RFC Format Framework December 2015
o The plain-text format will be UTF-8 encoded; non-ASCII characters
will be allowed.
o A Byte Order Mark (BOM) will be added at the start of each file.
o Widow and orphan control for the plain-text publication format
will not have priority for the developers creating the rendering
code [TYPOGRAPHY].
o Authors may choose to have pointers to line art in other
publication formats in place of ASCII art in the .txt file.
o A paginated plain-text file will be created that includes a form
feed instruction every 58 lines (at most), including blank lines.
Instructions or a s cript will be made available by and for the
community to strip out pagination as per individual preference.
o Running headers and footers will not be used.
7.4. Potential Future Publication Formats
7.4.1. EPUB
This format is intended for use by ebook readers and will be
available for RFCs after the requirements have been defined. No
draft is currently available.
8. Figures and Artwork
8.1. SVG
[I-D.brownlee-svg-rfc] Describes the profile for SVG line art. SVG
is an XML-based vocabulary for creating line drawings; SVG
information will be embedded within the canonical XML at time of
publication.
9. Content and Page Layout
9.1. Non-ASCII Characters
There are security and readability implications to moving outside the
ASCII range of characters. [I-D.flanagan-nonascii] focuses on
exactly where and how non-ASCII characters may be used in an RFC,
with an eye towards keeping the documents as secure and readable as
possible given the information that needs to be expressed.
Flanagan Expires June 11, 2016 [Page 9]
Internet-Draft RFC Format Framework December 2015
9.2. Style Guide
The RFC Style Guide [RFC7322] was revised to remove as much page
formatting information as possible, focusing instead on grammar,
structure, and content of RFCs. Some of the changes recommended,
however, informed the XML v3 vocabulary.
9.3. CSS Requirements
A Cascading Style Sheet (CSS) is required to allow the HTML format to
be accessible and flexible across a variety of devices. Requirements
for the CSS that will be included with the HTML output are captured
in [I-D.flanagan-rfc-css].
10. Transition Plan
10.1. Statement of Work and RFP for Tool Development
Existing tools for the creation of RFCs will need to be updated, and
new tools created, to implement the updated format. As the
requirements gathering effort, described in the various documents
described earlier int this draft, finishes the bulk of the work, the
Tools Development Team of the IETF will work with the RSE to develop
Statements of Work (SoWs). Those SoWs will first be reviewed within
the Tools Development Team, the Tools Management Committee, and go
out for a public comment period. After public review, the SoWs will
be attached to a Request for Proposal (RFP) and posted as per the
IASA bid process [IASA-RFP].
Once bids have been received, reviewed, and awarded, coding will
begin.
10.2. Testing and Transition
During the I-D review and approval process, authors and stream-
approving bodies will select drafts to run through the proposed new
publication process. While the final RFCs published during this time
will continue as plain-text and immutable once published, the
feedback process is necessary to bootstrap initial testing. These
early tests will target finding issues with the proposed xml2rfc v3
vocabulary that result in poorly formed publication formats as well
as issues that prevent proper review of submitted drafts.
Feedback will result in regular iteration of the basic code and XML
vocabulary. In order to limit the amount of time the RFC Production
Center (RPC) spends on testing and QA, note that their priority is to
edit and publish documents, community assistance will be necessary to
help move this stage along. A mailing list and experimental source
Flanagan Expires June 11, 2016 [Page 10]
Internet-Draft RFC Format Framework December 2015
directory on the RFC Editor website will be created for community
members willing to assist in the detailed review of the XML and
publication formats. Editorial checks of the publication formats by
the community are out of scope; the focus will be the QA of each
available output, checking for inconsistencies across formats.
The purpose of testing phase is to work with the community to
identify and fix bugs in the process and the code, before producing
canonical, immutable XML, and to collect additional feedback on the
usability of the new publication formats.
Success will be measured by the closure of all bugs which had been
identified by the RPC and the Tools Development team as fatal and
consensus on the readiness of the XML vocabulary and final XML files
for publication. The actual rendering engine can go through further
review and iteration, as the publication formats may be republished
as needed.
Authors are not required to submit their approved drafts in an XML
format; plain-text will also remain an option for the foreseeable
future. However, documents submitted as plain-text cannot include
such features as SVG artwork.
A known risk at this point of the transition is the difficulty in
quantifying the resources required from the RPC. This phase will
require more work on the part of the RPC to support both old and new
publication processes for at least six months. There is potential
for confusion as consumers of RFCs find some documents published at
this time with a full set of outputs, while other documents only have
plain text. There may be a delay in publication as new bugs are
found that must be fixed before the files can be converted into the
canonical format and associated publication formats.
Final success of the transition will be measured by the closure of
all bugs which had been identified by the RPC and the Tools
Development team as major or critical. There must also be rough
consensus from the community regarding the utility of the new
formats.
10.3. Completion
Authors may submit XML (preferred) or plain text. The XML drafts
submitted for publication will be converted to canonical XML format
and published with all available publication formats. All authors
will be expected to review the XML and the publication formats prior
to publication. Further process detail still under discussion.
Flanagan Expires June 11, 2016 [Page 11]
Internet-Draft RFC Format Framework December 2015
Success for this phase will be measured by a solid understanding by
the RSE and the IAOC of the necessary costs and resources required
for long-term support of the new format model.
11. IANA Considerations
This document has no actions for IANA.
12. Security Considerations
Changing the format for RFCs involves modifying a great number of
components to publication. Understanding those changes and the
implications for the entire tool chain is critical so as to avoid
unintended bugs that would allow unintended changes to text.
Unintended changes to text could in turn corrupt a standard, practice
or critical piece of information about a protocol.
