ADR 0005: Meeting Domain Model

Status

Accepted

Context

The application manages meetings as structured collections of related artifacts rather than as individual files.

A consistent domain model is required to support future extensions such as semantic search, knowledge extraction, versioning and database storage.

Decision

The central entity of the application is the Meeting.

A Meeting owns or references all artifacts created during its lifecycle.

The initial domain model consists of:

• Meeting
• Recording
• Transcript
• Working Transcript
• Speaker
• Participant
• AI Artifact
• Action Item
• Decision
• Knowledge Object
• Attachment

Each entity has a unique identifier.

Relationships between entities shall be maintained explicitly.

Consequences

• New artifact types can be added without changing the overall architecture.
• Storage implementation (files, SQLite, PostgreSQL, etc.) remains independent from the domain model.
• AI outputs become first-class entities rather than generated text files.
• Future integrations can operate on domain objects instead of file names.
