TL;DR

FLOSS architecture is often undocumented or scattered across communication channels, and the links among architectural work, governance, and ethical commitments remain underexplored. This project combines multi-method case studies with framework and intervention design, then pilots practices and teaching formats in projects and courses. It aims to produce cross-case evidence, a conceptual framework, and lightweight approaches for more explicit and inclusive architectural work.

  • Problem

    The project addresses limited evidence on how FLOSS architecture emerges across artifacts, communication, governance, and ethical concerns, including how lightweight practices can improve knowledge accessibility without substantial maintainer overhead.

  • Method

    The research uses three phases: multi-method case studies, framework and lightweight practice design, and pilot evaluation in FLOSS projects and courses.

  • Results

    The expected results are cross-case empirical evidence, a conceptual framework linking architecture practices to socio-technical and ethical dimensions, and lightweight practices and teaching formats.

  • Takeaways & Limitations

    The project aims to support more explicit, inclusive, and reflective architectural work in FLOSS practice and FLOSS-based teaching.

Abstract

from arXiv · show

This project investigates how software architecture practices in Free/Libre Open Source Software (FLOSS) are shaped by socio-technical and ethical factors, and how education can support more explicit, inclusive, and reflective architectural work. Motivated by FLOSS's role in digital sovereignty, it is observed that architectural decisions are often undocumented and scattered across issues, pull requests, and mailing lists. While prior research has studied architectural artifacts, erosion, and communication, the interplay between architectural work, governance arrangements, and ethical commitments in FLOSS remains underexplored. The research follows a three-phase design: (1) multi-method case studies of 3-4 domain-pairs of architecturally non-trivial FLOSS projects, (2) framework and intervention design with practitioners and educators, and (3) pilot evaluations in projects and courses. It will produce (i) cross-case empirical evidence on FLOSS architecture practices, (ii) a conceptual framework linking architecture practices to socio-technical conditions and ethical dimensions, and (iii) lightweight practices and teaching formats that render architectural work more explicit and inclusive.

I. INTRODUCTION

FLOSS architecture is often implicit and distributed across communication channels, while existing research rarely connects architectural practice with governance and ethical concerns. This project addresses that gap through case studies, a conceptual framework, and lightweight interventions for practice and education.

  • Problem and motivation: FLOSS projects often rely on partially documented architectural knowledge distributed across issues, pull requests, and mailing lists.This fragmentation can make architectural rationale difficult to locate, reuse, and transfer.
  • Project response: The project uses multi-method case studies followed by framework development and formative evaluation of lightweight practices and teaching formats.Its expected contributions are cross-case evidence, a conceptual framework, and actionable interventions for FLOSS practice and education.
  • Research gap: Prior research treats architectural artifacts, communication, governance, ethics, and education as related but insufficiently integrated strands.The project specifically connects day-to-day architectural work with governance arrangements and ethical concerns such as stewardship, responsibility, and inclusivity.
  • Research gap: The central gap concerns how artifacts, communication routines, and governance arrangements jointly shape FLOSS architectural work and ethical participation.The project also examines how architectural knowledge can become more durable and accessible without imposing substantial maintainer overhead.

III. RESEARCH QUESTIONS AND OBJECTIVES

The research asks how socio-technical and ethical factors shape FLOSS architecture practices and how education can make this work more explicit, inclusive, and reflective. Its questions cover documentation, governance, teaching, and lightweight interventions, with an iterative design linking empirical findings to later evaluation.

  • Research questions: The overarching question examines how socio-technical and ethical factors shape FLOSS architecture practices and how education can make them more explicit, inclusive, and reflective.
  • Research design: The design is iterative: empirical findings refine later questions, sampling, data collection, and interventions, while educational formats are evaluated as a core project component.
  • Research questions: The research asks how projects document, communicate, and coordinate architecture, and how governance, communication structures, and ethics shape participation and rationale preservation.
  • Research questions: It also examines how FLOSS-based courses teach architectural decision-making and socio-technical responsibilities.
  • Research questions: A further question concerns which lightweight practices and educational formats can improve explicitness and accessibility without increasing maintainer workload.

B. Objectives

The objectives characterize FLOSS architecture practices, analyze their socio-technical and ethical dimensions, examine architecture education, and develop lightweight practices and educational patterns. Together, they connect empirical analysis to a framework and practical interventions.

  • Objectives: The objectives systematically characterize architecture artifacts, communication channels, and decision-making mechanisms in selected FLOSS projects.
  • Objectives: They analyze how socio-technical and ethical factors shape architectural practices and knowledge distribution.
  • Objectives: They examine whether FLOSS-based teaching presents software architecture together with socio-technical and ethical aspects.
  • Objectives: They develop a conceptual framework linking architecture practices, socio-technical conditions, and ethical considerations in FLOSS.
  • Objectives: They design and preliminarily evaluate lightweight architectural practices and educational patterns supporting more explicit and reflective architecture work.

IV. METHODOLOGY

The methodology combines repository mining, communication analysis, and interviews to study both observable architectural artifacts and tacit decision-making. It proceeds through information gathering, solution generation, and evaluation, producing case-level maps of knowledge, participation, and socio-technical factors.

  • Research design: The study combines repository mining, communication analysis, and semi-structured interviews across three iterative phases: information gathering, solution generation, and evaluation.The combination is intended to capture observable artifacts and tacit knowledge without treating social and technical aspects in isolation.
  • Case outputs: Each case describes the project’s architectural knowledge base, including artifacts and their traceability.
  • Case outputs: Each case maps decision points and participation pathways by identifying who proposes, discusses, and approves architecture-relevant changes.
  • Case outputs: The case analysis identifies socio-technical and ethical factors shaping architectural work, while Table II maps research questions to data sources and methods.

A. Phase 1: Information Gathering and Interpretation

Phase 1 combines literature review, comparative case selection, repository and communication analysis, interviews, and educational-material analysis to characterize FLOSS architectural practices and their socio-technical and ethical dimensions.

  • A systematic literature review covers FLOSS architecture practice, architectural erosion and smells, architecture-knowledge communication, and FLOSS-based education.
  • The study examines 3–4 domain-pairs with comparable architectural cores but differing governance, subject to repository, communication-channel, and recruitment feasibility.Candidate pairs include office suites, cryptographic toolchains, package managers, messaging ecosystems, and theorem provers.
  • Repository mining extracts architecture-related artifacts and dependency graphs, while architectural recovery provides views of coupling and modularity.The analysis also derives quantitative proxies for governance, participation, and other conceptual dimensions where possible.
  • Issues, pull requests, and mailing-list archives are mined with keyword and metadata filters, manually validated samples, and iteratively refined architectural-decision criteria.Semi-structured interviews complement trace analysis by addressing knowledge that is not directly observable in project artifacts.
  • Phase 1 will produce descriptive accounts of current practices, initial socio-technical and ethical insights, and a baseline of architecture teaching in FLOSS-based courses.These findings will refine later research questions, sampling strategies, and data-collection instruments.

B. Phase 2: Solution Generation Based on Findings

Phase 2 uses Phase 1 patterns and stakeholder input to construct a framework linking architectural practice with socio-technical and ethical factors, then design lightweight practices and educational formats.

  • Phase 2 constructs a framework relating observed architectural practices to governance, communication structures, roles, inclusivity, responsibility, and stewardship.
  • Proposed interventions include adapted decision-documentation templates, guidance for involving newcomers, visible architectural constraints, and prototype educational resources.
  • The research approach is an iterative three-phase design in which empirical findings and stakeholder input generate context-sensitive and realistic solutions.
  • Inputs include FLOSS repository code, architecture decision records, issues, mailing lists, and governance or role descriptions.

C. Phase 3: Evaluation of Proposed Solutions

Phase 3 pilots proposed architectural practices in FLOSS projects and educational formats in courses, collecting feedback while applying triangulation, auditability, peer review, member checking, negative-case analysis, and reflexivity.

  • Pilots evaluate documentation or meeting practices in one or two FLOSS projects and educational prototypes in teaching settings through qualitative feedback from contributors and students.Feedback addresses feasibility, perceived usefulness, and effects on understanding and participation.
  • Multiple sources will be triangulated, including repositories, artifacts, communication logs, interviews, and educational materials, with converging and diverging evidence compared.
  • An audit trail records coding, sampling, inclusion and exclusion decisions, codebook changes, and analysis scripts, with sharing of deidentified or aggregated materials where feasible.
  • Key risks include limited maintainer access, incomplete architectural-rationale traceability, incomplete governance-model coverage, and the evolving role of generative AI.The design also includes peer debriefing, member checking, negative-case analysis, reflexivity, and ethical safeguards for interviews and trace data.
  • LLM assistance with architectural decisions or ADRs will be recorded to assess possible effects on decision authority and knowledge distribution without expanding the project’s scope.
  • The study addresses communication-trace misclassification by triangulating sensitive interpretations with interviews and reporting them cautiously.

V. EXPECTED RESULTS

The expected results combine cross-case evidence, explanatory analysis, a conceptual framework, and lightweight interventions linking FLOSS architecture practice with governance, participation, ethics, and education.

  • Cross-case empirical evidence will describe how architectural practices are carried out and communicated, including artifacts, communication patterns, and recurring challenges.
  • The outputs include pragmatic guidance relevant to researchers, FLOSS practitioners, and educators, alongside publications and possible open research data and scripts subject to ethical and licensing constraints.
  • Explanatory analysis will connect roles, governance, and community norms with knowledge distribution, participation, and architectural decision-making.
  • The project will deliver a conceptual framework linking architecture practices, socio-technical conditions, and ethical considerations in FLOSS.
  • Lightweight practices and educational patterns will support explicit, inclusive, and reflective architecture work in FLOSS projects and teaching.

VI. RESEARCH PLAN AND MILESTONES

The research plan presents a timeline and milestones, while allowing schedule refinement in response to project access and early empirical findings.

  • The schedule may be refined as access to projects and early empirical findings develop.
  • The timeline is presented as provisional rather than fixed.
  • The project sets out planned milestones in a dedicated timeline.

VII. FEEDBACK SOUGHT

The project seeks feedback on how to operationalize architectural responsibility and decision power, structure comparative cases, and design feasible interventions for FLOSS practice and education.

  • The project asks which proxies and analysis strategies can defensibly characterize architectural responsibility and decision power in FLOSS traces.
  • It seeks advice on whether paired, diverse cases are suitable for cross-case synthesis or should be narrowed.
  • It asks which lightweight interventions are realistic in FLOSS practice and education without increasing maintainer workload.
