Software Architect and Developer at Personal project
Recurring problem in my own AI-assisted projects: requirements analysis, use cases, and architecture decisions can be created quickly with AI support, but remain difficult to follow and scattered across Markdown files – knowledge is lost as soon as it is no longer in the context window. arknet turns requirements engineering and architecture knowledge into structured, verifiable data instead of plain text: requirements, use cases, and architecture decisions form a consistently linked knowledge graph, traceable from requirement to architecture decision – queryable by both people and AI agents. Technically based on RDF/OWL and a custom MCP server.
Result: Working MCP daemon, Docker image published automatically to GHCR, nine hexagonal modules, eleven ADRs (including an Open-Core licensing model). Requirements engineering and Ubiquitous Language hexagons are active. Public as a Community Edition under Apache-2.0 since 07/2026 (github.com/kogn-io/arknet), together with the Claude Code plugin and GHCR image; Open-Core model.

About the technology
Architecture Documentation
arc42 is a practical template for documenting software architecture. It gives teams a shared structure for describing goals, constraints, context, building blocks, runtime behavior, deployment and key decisions. The template is technology-neutral, so it works with monoliths, distributed systems, cloud services and embedded software. Its purpose is not to prescribe an architecture, but to make important architectural knowledge easier to understand, review and maintain.
Core Sections
An arc42 document connects the views that matter during design and delivery. Typical content includes:
- Requirements, quality goals and constraints
- System scope, context and interfaces
- Building blocks and runtime scenarios
- Deployment views and cross-cutting concepts
- Architecture decisions and risks
Strong documentation explains why a structure exists, not only what components are present.
Ecosystem And Tools
arc42 can live in a wiki, repository or documentation site alongside the source code. Specialists often combine it with Markdown, Git, diagrams, C4 models, UML, Mermaid or PlantUML. Architecture decision records can complement the decision section, while automated documentation checks help keep diagrams and written views aligned with system changes. The method fits agile delivery when teams update documentation as decisions evolve.
When Companies Need It
Companies bring in arc42 expertise when architecture knowledge is fragmented, a platform is being modernized or several teams need a common technical view. Freelance specialists can establish a documentation baseline, interview product and engineering stakeholders, and turn complex systems into usable architecture views. This is especially valuable during migration, integration, handover and due diligence work. In Munich, on-site workshops can support teams that need close collaboration, while remote delivery works well for repository-based documentation.
Specialist Capabilities
A strong arc42 professional combines architecture judgment with precise communication. They can separate facts from assumptions, identify missing decisions and adapt the level of detail to each audience. Useful adjacent skills include domain modeling, API design, cloud architecture, security, observability and facilitation. They should be comfortable reading unfamiliar code and validating documentation against the running system rather than relying only on interviews.
Quality And Maintenance
Good arc42 documentation is concise, consistent and connected to real decisions. It names important interfaces, dependencies, risks and quality goals without turning into an inventory of every class or service. Reviewers should be able to trace a major requirement to architectural choices and deployment consequences. A capable specialist also defines ownership, review points and lightweight update habits so the document remains useful after the engagement ends.
Frequently asked questions
The facts hiring teams ask for most often when it comes to arc42.
arc42 is used to document software architecture in a structured, technology-neutral way. It helps teams explain system context, building blocks, runtime behavior, deployment, quality goals and important decisions. Companies use it for new designs, modernization, handover and ongoing architecture communication.
arc42 is a documentation structure, while C4 and UML are mainly modeling and diagramming approaches. They work well together: arc42 provides the sections and narrative, while C4 or UML can provide visual views inside those sections. A specialist selects the simplest notation that communicates the decision clearly.
arc42 work benefits from architecture experience, domain modeling and strong technical writing. Depending on the system, useful related skills include cloud platforms, APIs, security, data design, observability, event-driven systems and diagram tools such as PlantUML or Mermaid. Workshop facilitation is also important when several teams own different parts of the system.
arc42 does not require a large program or a particular technology stack. The right level of experience depends on system complexity, stakeholder count and the quality of existing knowledge. A smaller engagement may need documentation structure and review, while a modernization program may require deep architecture analysis, decision capture and stakeholder workshops.
arc42 is well suited to remote collaboration when documents, diagrams and decisions are stored in a shared repository or wiki. Remote specialists can run interviews and reviews through collaborative workshops. For teams in Munich, occasional on-site sessions can help resolve difficult domain questions, but they are not essential for every project.
arc42 documentation should help a new reader understand the system and the reasoning behind its structure. Check whether requirements, constraints, interfaces, dependencies, risks and decisions are consistent across the views. Good work is concise, validated with stakeholders and connected to a clear maintenance process.
arc42 does not replace architecture decision records. Its decision section can summarize major choices, while separate records preserve context, alternatives, consequences and approval details over time. A freelancer should define how both forms link together without duplicating information.
arc42 specialists need more than familiarity with the template. Strong professionals can inspect a real system, ask focused questions, expose hidden assumptions and express architecture at the right level of detail. They also know when a diagram, decision record or short explanation is more useful than adding another document section.
