Prepare documents
RFC dependency checker
Joe Touch
A script to check the references in Internet Drafts for dependencies and updates.
Bibtex Citation Converter
Yaron Sheffer
This tools converts bibtex-formatted citations into the bibxml format used in xml2rfc. Many (if not most) academic papers have bibtex citations available online, and the tool makes it easier to reference them in Internet Drafts.
Templates for xml2rfc work
Elwyn Davies
Elwyn Davies has produced a template as a starting point for writing drafts using xml2rfc. You can find a copy of the schema v3 version of the XML template at
Draft Submission API
Henrik Levkowetz
A simplified draft submission interface, intended for automation, is available at G-Star Raw Men's Rovic Zip 3D Straight Tapered Fit Casual Pants.
The interface accepts only xml uploads which can be processed on the server, and requires the user to have a datatracker account. A successful submit still requires the same email confirmation roundtrip as submissions done through the regular submission tool.

BibXML to Markdown Converter
Yaron Sheffer
This simple script, bibxml2md, converts bibxml references extracted from xml2rfc files into markdown, for use in kramdown-rfc2629 Internet Drafts.
License File for Open Source Repositories
Many working groups work with open source repositories, even for their work on specifications. The IESG has made a boilerplate text available for inclusion in repositories, available at the URL above.
Write RFCs using wiki-style markup ('markdown')
Miek Gieben
Pandoc2rfc (see RFC 7328) uses Markdown in combination with Make and XSLT scripting to produce internet-drafts in XML format from plain text input. The plain text only needs a few formatting conventions, more or less like wiki markup. See also these OSX installation tips.
Draft Submission
Henrik Levkowetz
The New Internet Draft Submission Tool replaces the older Draft Submission Tool and the even older email submission workflow, and lets an author submit a new or updated draft through a webpage, and have it appear in the archives immediately.
XML to Office Open XML converter
Eric Vyncke
A converter from XML format into Office Open XML .DOCX format (i.e., readable notably by Microsoft Word for spelling / grammar checks)
Writing Internet-Drafts using Microsoft Word
Joe Touch
Use Microsoft Word or .doc-compatible editors to edit Internet Drafts. Word is a WYSIWYG editor that runs on Windows and Mac OSes, with an open-source variant (OpenOffice) that runs on Linux. This method is documented in RFC 5385 based on a template , using a post-processing Perl script.
Convert nroff for drafts and RFCs to RFC2629 format XML
This is a first release of nroff2xml. The tool is able to get nroff source and generate xml based on it. The output XML has well formed sections, paragraphs, and external references. The output can be successfully processed with xml2rfc. The author is not going to develop this further, as it's served its initial purpose in converting the .nroff source for RFC3315 to xml; other people are however very welcome to pick this up and refine it.
Grammar Checkers Wiki Page
A list of grammar / spelling checkers for I-D in XML format
A configuration for editing xml2rfc-format documents in XXE
Bill Fenner , Warren Kumari

This is a WYSIKN (What You See Is Kinda Neat) addon for the very configurable XMLMind XML Editor ("xxe"). The personal version of xxe is free and very capable.

The addon is capable of graphical editing of sections, anchors, lists, cross-references, etc. and allows word processor-like behavior of "enter" to create a new paragraph or list item. More info in the README.

Draft TXT and HTML from XML source (xml2rfc)
Henrik Levkowetz

xml2rfc will allow you to take your XML source (using the format defined in RFC 2629 and its unofficial successor) and generate well-formatted text and html versions of drafts from it.

Version 2 of xml2rfc is a complete rewrite in Python. It is available for installation from the Python Package Index (PyPi):
There's a tutorial available on how to install from PyPi, or if you're impatient you can try the following commands on the command line:
  pip install xml2rfc
if that fails:
  easy_install pip
  pip install xml2rfc
if that fails, go to the tutorial above.

Edit IDs in .nroff with wysiwyg display
Stefan Santesson
NroffEdit is a Java application for writing and editing Internet Draft files using the nroff format. This application lets you load any I-D nroff file, which will be shown processed in the right-hand window, and can be edited in the left-hand window.
Write Internet-Drafts using the LyX Editor.
Nico Williams , Yaron Sheffer
Use lyx2rfc togeter with LyX to edit Internet-Drafts. LyX is an open source WYSIWYM GUI editor that runs on all major operating systems. Currently lyx2rfc outputs XML, text, and HTML, but only runs on Linux.
CTLAMP sp-lamp-058 Replacement Lamp splamp-058 Compatible Lamp w
Ronald Tse
Asciidoctor-rfc is a tool that allows writing Internet-Drafts using AsciiDoc as an alternative to Kramdown / MMark or manual RFC XML. AsciiDoc is a widely-adopted textual format. Similar to Markdown, it is simple to write and easy to understand, but its major benefit is for being a structured format that directly converts into DocBook XML.
Fix document spacing.
Henrik Levkowetz
Fix up the spacing between sentences to use two spaces. (This is a small script written in awk).
Check internet-drafts for submission nits
Henrik Levkowetz
Use idnits to check that your draft has the desired formatting, boilerplate, references consistency and more.
Run a spelling-check on your internet-draft
Henrik Levkowetz
Idspell uses an IETF-specific wordlist built from the last 2 years' published RFCs, surnames of recent I-D authors and some manually added words.
HTML, PDF, or ePub from XML source
Julian Reschke
A set of XSLT transformations and shell scripts that can be used to transform RFCXML (RFC 2629, RFC 7749, RFC 7991) to various output formats, such as HTML, XHTML, PDF, or ePub. For more information, see the documentation.
Draft Diff Tool
Henrik Levkowetz
When looking at updated drafts, you want a diff with the previous draft which ignores changing page layout and moved page headers and footers. Get it here.
Add bcp14 markup to XML draft source
Joe Touch

Run this script in order to add <bcp14> elements around BCP 14 key words (MUST, SHOULD, etc.) in the XML source for an Internet-Draft.

Usage: file1.xml > file2.xml

Known defect: there may be stray elements in comments, sourcecode, and artwork.

Templates for MIB Documents
David B. Harrington
The MIB Doctors have produced three templates specifically aimed at drafts containing MIB modules:
• The first is an XML template for editors that use XML2RFC. Some advice echoing guidelines from RFC4181 is embedded in comments.
• A second template is a text template for MIB documents with advice embedded in the document.
• A third template is a plain text template with no advice included.

Validate XML input for XML2RFC

Access IETF-related files from the command line
Paul Hoffman
The "ietf" program lets you access IETF-related files from the command line. It creates a local copy of these files on your computer using rsync, and gives a friendly way to access them. You can give commands from your normal shell, or you can run an interactive shell that is part of the program.

Print an Internet Draft (ID) or RFC as PDF.
Warren Kumari
Because of the difference between the number of lines on laser printers and line / dot-matrix printers, each "page" of the draft actually takes up 2 pages and you end up with lots of pages with just a one line footer. This script tries to fix that by downloading the draft, converting it to a PDF and then printing it.
Downloading RFCs & I-Ds eBooks
Tero Kivinen
There is weekly generated ebooks in .epub and .mobi (kindle) format for RFCs and Internet-Drafts. The and rfc.epub files contains all RFCs in one big file. For I-Ds there is files for each separate working group (i-d.*) and one file per area containing all WGs in the area (area.*). In addition to the active WG drafts those files also contain the published RFCs and related I-Ds.

WG Issue Trackers
Henrik Levkowetz
All IETF Working Groups have issue trackers set up to facilitate tracking of document issues. The wiki for each WG is at<ACRONYM>, and you can see tickets at<ACRONYM>/report/1. The issue tracker is automatically updated with ticket (issue) component names matching the WG drafts. New tickets can be added (login with your datatracker login is needed) at<ACRONYM>/newticket. The WG page in the datatracker has link to the group wiki and issue tracker under the 'About' tab.

WG Subversion Repositories
Henrik Levkowetz
Some IETF Working Groups have subversion repositories set up, to facilitate cooperative editing and change tracking. To find the repository of a WG, please go to the WG status page and follow the link which says 'Svn' in the top horizontal menubar. If there is no such link, the WG doesn't have a registered issue tracker. In order to check out a document from the repository, find the svn url to it, then use:
svn co <document-url>

Email aliases to draft authors and chairs
Henrik Levkowetz provides email aliases to WG chairs and draft authors, to make it easier to reach them without having the individual addresses available. To reach the authors of a draft, send an email to:
[See the complete draft alias file]

In a similar manner, to reach a WG's Chairs or ADs, send an email to:
<WG> or
<WG>, respecitvely.
On each WG page in the datatracker, there's a tab that shows the list of aliases for that WG; see for example AX Armani Exchange Men's Low-top Sneakers]

Validate the signature for an Internet-Draft
Russ Housley
RFC 5485 specifies a mechanism to provide a cryptographic signature for valid internet drafts. The Cryptographic Message Syntax (CMS) is used to create a detached signature, which is stored in a separate companion file so that no existing utilities are impacted by the addition of the digital signature. This scripts provides a way to verify these signatures.
