1. Introduction

 The IETF, as an international Standards Developing Organization
 (SDO), hosts a diverse set of data about the IETF's history and
 development, current standardization activities, Internet protocols,
 and the institutions that comprise the IETF.  A large portion of this
 data is publicly available, yet it is underutilized as a tool to
 inform the work in the IETF or the broader research community that is
 focused on topics like Internet governance and trends in information
 and communication technologies (ICT) standard setting.
 The aim of the "IAB Workshop on Analyzing IETF Data (AID) 2021"
 workshop was to study how IETF data is currently used, to understand
 what insights can be drawn from that data, and to explore open
 questions around how that data may be further used in the future.
 These questions can inform a research agenda drawing from IETF data
 that fosters further collaborative work among interested parties,
 ranging from academia and civil society to industry and IETF
 leadership.

2. Workshop Scope and Discussion

 The workshop was organized with two all-group discussion slots at the
 beginning and the end of the workshop.  In between, the workshop
 participants organized hackathon activities based on topics
 identified during the initial discussion and in submitted position
 papers.  The following topic areas were identified and discussed.

2.1. Tools, Data, and Methods

 The IETF holds a wide range of data sources.  The main ones used are
 the mailinglist archives [Mail-Arch], RFCs [IETF-RFCs], and the
 datatracker [Datatracker].  The latter provides information on
 participants, authors, meeting proceedings, minutes, and more
 [Data-Overview].  Furthermore, there are statistics for the IETF
 websites [IETF-Statistics], the working group Github repositories,
 and the IETF survey data [Survey-Data].  There was discussion about
 the utility of download statistics for the RFCs themselves from
 different repos.
 There is a wide range of tools to analyze this data produced by IETF
 participants or researchers interested in the work of the IETF.  Two
 projects that presented their work at the workshop were BigBang
 [BigBang] and Sodestream's IETFdata [ietfdata] library.  The RFC
 Prolog Database was described in a submitted paper; see
 [Prolog-Database].  These projects could provide additional insight
 into existing IETF statistics [ArkkoStats] and datatracker statistics
 [DatatrackerStats], e.g., gender-related information.  Privacy issues
 and the implications of making such data publicly available were
 discussed as well.
 The datatracker itself is a community tool that welcomes
 contributions; for example, for additions to the existing interfaces
 or the statistics page directly, see the Datatracker Database
 Overview [Data-Overview].  At the time of the workshop, instructions
 about how to set up a local development environment could be found at
 IAB AID Workshop Data Resources [DataResources].  Questions or
 discussion about the datatracker and possible enhancements can be
 sent to tools-discuss@ietf.org.

2.2. Observations on Affiliation and Industry Control

 A large portion of the submitted position papers indicated interest
 in researching questions about industry control in the
 standardization process (as opposed to individual contributions in a
 personal capacity), where industry control covers both a) technical
 contributions and the ability to successfully standardize these
 contributions and b) competition on leadership roles.  To assess
 these questions, investigating participant affiliations, including
 "indirect" affiliations (e.g., by tracking funding and changes in
 affiliation) was discussed.  The need to model company
 characteristics or stakeholder groups was also discussed.
 Discussion about the analysis of IETF data shows that affiliation
 dynamics are hard to capture due to the specifics of how the data is
 entered and because of larger social dynamics.  On the side of IETF
 data capture, affiliation is an open text field that causes people to
 write their affiliation down in different ways (e.g., capitalization,
 space, word separation, etc).  A common data format could contribute
 to analyses that compare SDO performance and behavior of actors
 inside and across standards bodies.  To help with this, a draft data
 model was developed during the hackathon portion of the workshop; the
 data model can be found in Appendix A.
 Furthermore, there is the issue of mergers, acquisitions, and
 subsidiary companies.  There is no authoritative exogenous source of
 variation for affiliation changes, so hand-collected and curated data
 is used to analyze changes in affiliation over time.  While this
 approach is imperfect, conclusions can be drawn from the data.  For
 example, in the case of mergers or acquisition where a small
 organization joins a large organization, this results in a
 statistically significant increase in likelihood of an individual
 being put in a working group chair position (see the document by
 Baron and Kanevskaia [LEADERSHIP-POSITIONS]).

2.3. Community and Diversity

 The workshop participants were highly interested in using existing
 data to better understand who the current IETF community is.  They
 were also interested in the community's diversity and how to
 potentially increase it and thereby increase inclusivity, e.g.,
 understanding if there are certain factors that "drive people away"
 and why.  Inclusivity and transparency about the standardization
 process are generally important to keep the Internet and its
 development process viable.  As commented during the workshop
 discussion, when measuring and evaluating different angles of
 diversity, it is also important to understand the actual goals that
 are intended when increasing diversity, e.g., in order to increase
 competence (mainly technical diversity from different companies and
 stakeholder groups) or relevance (also regional diversity and
 international footprint).
 The discussion on community and diversity spanned from methods that
 draw from novel text mining, time series clustering, graph mining,
 and psycholinguistic approaches to understand the consensus mechanism
 to more speculative approaches about what it would take to build a
 feminist Internet.  The discussion also covered the data needed to
 measure who is in the community and how diverse it is.
 The discussion highlighted that part of the challenge is defining
 what diversity means and how to measure it, or as one participant
 highlighted, defining "who the average IETFer is".  There was a
 question about what to do about missing data or non-participating or
 underrepresented communities, like women, individuals from the
 African continent, and network operators.  In terms of how IETF data
 is structured, various researchers mentioned that it is hard to track
 conversations because mail threads split, merge, and change.  The
 ICANN-at-large model came up as an example of how to involve relevant
 stakeholders in the IETF that are currently not present.  Conversely,
 it is also interesting for outside communities (especially policy
 makers) to get a sense of who the IETF community is and keep them
 updated.
 The human element of the community and diversity was highlighted.  In
 order to understand the IETF community's diversity, it is important
 to talk to people (beyond text analysis).  In order to ensure
 inclusivity, individual participants must make an effort to, as one
 participant recounted, tell them their participation is valuable.

2.4. Publications, Process, and Decision Making

 A number of submissions focused on the RFC publication process, on
 the development of standards and other RFCs in the IETF, and on how
 the IETF makes decisions.  This included work on technical decisions
 about the content of the standards, on procedural and process
 decisions, and on questions around how we can understand, model, and
 perhaps improve the standards process.  Some of the work considered
 what makes an RFC successful, how RFCs are used and referenced, and
 what we can learn about the importance of a topic by studying the
 RFCs, Internet-Drafts, and email discussions.
 There were three sets of questions to consider in this area.  The
 first question related to the success and failure of standards and
 considered:
  • What makes a successful and good RFC?
  • What makes the process of making RFCs successful?
  • How are RFCs used and referenced once published?
 Discussion considered how to better understand the path from an
 Internet-Draft to an RFC, to see if there are specific factors that
 lead to successful development of an Internet-Draft into an RFC.
 Participants explored the extent to which this depends on the
 seniority and experience of the authors, on the topic and IETF area,
 on the extent and scope of mailing list discussion, and other
 factors, to understand whether success of an Internet-Draft can be
 predicted and whether interventions can be developed to increase the
 likelihood of success for work.
 The second question focused on decision making.
  • How does the IETF make design decisions?
  • What are the bottlenecks in effective decision making?
  • When is a decision made? And what is the decision?
 Difficulties here lie in capturing decisions and the results of
 consensus calls early in the process, and understanding the factors
 that lead to effective decision making.
 Finally, there were questions regarding what can be learned about
 protocols by studying IETF publications, processes, and decision
 making.  For example:
  • Are there insights to be gained around how security concerns are

discussed and considered in the development of standards?

  • Is it possible to verify correctness of protocols and detect

ambiguities?

  • What can be learned by extracting insights from implementations

and activities on implementation efforts?

 Answers to these questions will come from analysis of IETF emails,
 RFCs and Internet-Drafts, meeting minutes, recordings, Github data,
 and external data such as surveys, etc.

2.5. Environmental Sustainability

 The final discussion session considered environmental sustainability.
 Topics included what the IETF's role with respect to climate change,
 both in terms of what is the environmental impact of the way the IETF
 develops standards and in terms of what is the environmental impact
 of the standards the IETF develops.
 Discussion started by considering how sustainable IETF meetings are,
 focusing on the amount of carbon dioxide (CO2) emissions IETF
 meetings are responsible for and how can we make the IETF more
 sustainable.  Analysis looked at the home locations of participants,
 meeting locations, and carbon footprint of air travel and remote
 attendance to estimate the CO2 costs of an IETF meeting.  While the
 analysis is ongoing, initial results suggest that the costs of
 holding multiple in-person IETF meetings per year are likely
 unsustainable in terms of CO2 emission.
 The extent to which climate impacts are considered during the
 development and standardization of Internet protocols was discussed.
 RFCs and Internet-Drafts of active working groups were reviewed for
 relevant keywords to highlight the extent to which climate change,
 energy efficiency, and related topics were considered in the design
 of Internet protocols.  This review revealed the limited extent to
 which these topics have been considered.  There is ongoing work to
 get a fuller picture by reviewing meeting minutes and mail archives
 as well, but initial results show only limited consideration of these
 important issues.

3. Hackathon Report

 The middle two days of the workshop were organized as a hackathon.
 The aims of the hackathon were to 1) acquaint people with the
 different data sources and analysis methods, 2) seek to answer some
 of the questions that came up during presentations on the first day
 of the workshop, and 3) foster collaboration among researchers to
 grow a community of IETF data researchers.
 At the end of Day 1, the plenary presentation day, people were
 invited to divide themselves into groups and select their own
 respective facilitators.  All groups had their own work space and
 could use their own communication methods and channels.  Furthermore,
 daily check-ins were organized during the two hackathon days.  On the
 final day, the hackathon groups presented their work in a plenary
 session.
 According to the co-chairs, the objectives of the hackathon have been
 met, and the output significantly exceeded expectations.  It allowed
 more interaction than academic conferences and produced some actual
 research results by people who had not collaborated before the
 workshop.
 Future workshops that choose to integrate a hackathon could consider
 asking participants to submit issues and questions beforehand
 (potentially as part of the position papers or the sign-up process)
 to facilitate the formation of groups.
