Kindred Silo
Item database and part management system.
Overview
Kindred Silo is an R&D-oriented item database with:
- Configurable part number generation via YAML schemas
- Revision tracking with append-only history, rollback, comparison, and status labels
- BOM management with multi-level expansion, flat BOM flattening, assembly costing, where-used queries, CSV/ODS export
- Authentication with local (bcrypt), LDAP/FreeIPA, and OIDC/Keycloak backends
- Role-based access control (admin > editor > viewer) with API tokens and sessions
- ODS import/export for items, BOMs, and project sheets
- Audit/completeness scoring with weighted per-category property validation
- Web UI — React SPA (Vite + TypeScript, Catppuccin Mocha theme) for item browsing, project management, schema editing, and audit
- CAD integration via REST API (silo-mod, silo-calc)
- Physical inventory tracking with hierarchical locations (schema ready)

Quick Start
See the Installation Guide for complete setup instructions.
Docker Compose (quickest — includes PostgreSQL, OpenLDAP, and Silo):
./scripts/setup-docker.sh
docker compose -f deployments/docker-compose.allinone.yaml up -d
Development (local Go + Docker services):
make docker-up # Start PostgreSQL in Docker
make run # Run silo locally with Go
When auth is enabled, a default admin account is created on first startup using the credentials in config.yaml under auth.local.default_admin_username and auth.local.default_admin_password.
# CLI usage
go run ./cmd/silo register --schema kindred-rd --category F01
Configuration
See config.example.yaml for all options.
Authentication
Silo supports three authentication backends, configured in config.yaml:
| Backend | Description |
|---|---|
| Local | Built-in accounts with bcrypt passwords |
| LDAP | FreeIPA / Active Directory integration |
| OIDC | Keycloak / OpenID Connect providers |
Roles: admin (full access) > editor (create/modify items) > viewer (read-only).
API tokens provide programmatic access for scripts and CAD clients. Set auth.enabled: false for development without authentication.
See docs/AUTH.md for full details.
Client Integrations
CAD and spreadsheet integrations are maintained in separate repositories:
The server provides the REST API and ODS endpoints consumed by these clients.
