GeneWeb
Web-based genealogy database and viewer written in OCaml

GeneWeb is a genealogy application that provides a lightweight web server and a browser-based UI to manage, view and share genealogical databases. It is implemented in OCaml and designed to handle large numbers of individuals, multilingual content and interactive relationship calculations.
Key Features
- Web-based interface served by an embedded lightweight HTTP server for daemon or CGI deployments
- Native OCaml core with JavaScript/HTML/CSS frontend components
- Import and export support for GEDCOM and GeneWeb GW formats, preserving incompatible data in notes
- Multilingual UI and wikitext-style notes with internal links, images and templates
- Efficient relationship and consanguinity calculators and family graph navigation
- Per-database accounts and per-person access filtering, with configurable privacy rules
- Statistics and timeline views (anniversaries, age pyramids, recent events)
- gwsetup and administrative tooling for configuration and base management; can run via container or standard build
Use Cases
- Host and share family trees with controlled access and per-person privacy settings
- Maintain large public or research genealogical databases with multilingual content and relationship analysis
- Import legacy GEDCOM data, edit with rich notes and export cleaned GW or GEDCOM datasets for archival
Limitations and Considerations
- Uses a custom GW data format rather than a mainstream RDBMS, which can limit direct integration with external database tools
- Primary implementation in OCaml may require specific build tooling and familiarity for custom development or packaging
GeneWeb is suited for genealogists and research projects that need a scalable, privacy-aware web front end and robust relationship analysis. It prioritizes compact, efficient data handling and multilingual publishing over modern single-page UI frameworks.
