Same content as TNCSC_Handbook.md, styled to match the version published as a shareable Artifact web page. Self-contained (Google Fonts is the only external dependency) so it works opened directly in a browser or served from any static host, without relying on the Artifact platform.
Community OS
A brand-neutral, resellable suite of Odoo 19 Community modules for community and cultural organizations. First deployment: the Tamil Nadu Cultural Society of Canada (TNCSC).
Vendor: Metatroncube Software Solutions LLP · Waterloo, Ontario Target platform: Odoo 19 Community Edition (LGPL-3) · PostgreSQL 16 · Python 3.12
community_*is a placeholder module prefix. Replace it with a unique vendor prefix before publishing to the Odoo App Store so technical names never collide with anything already listed.

Product-layer modules never mention a client name, never hardcode a price,
a colour, an account code, or an email address. Anything client-specific
is a configuration record, seeded only by a *_deployment module. Landing
a new client means writing a new clientname_deployment module — the
product code never changes.
Modules
Product layer (brand-neutral, sellable)
| Module | Purpose |
|---|---|
community_theme_base |
Configurable brand tokens (colours, logo, fonts) via settings |
community_membership |
Member profiles, tiers, family grouping, renewals, QR membership card |
event_qr_ticketing |
QR ticket per event registration, staff check-in / verification |
community_school |
Programs, classes, enrollment, attendance, LMS link, parent portal |
community_classifieds |
Member-gated classifieds board with moderation and auto-expiry |
community_benefits |
Benefit centres and per-tier member benefit entitlements |
community_interac |
Interac e-Transfer semi-automated payment provider (Canada) |
community_portal |
Unified member portal dashboard, soft-detects installed modules |
Deployment layer (per client — data only)
| Module | Purpose |
|---|---|
tncsc_deployment |
TNCSC branding, tiers/prices, chart of accounts, email copy, website pages, user groups |
Independent vs. bundled
Every product module installs standalone on a stock Odoo 19 CE with only
its declared Community-core dependencies — none require another
community_* module to function, with one deliberate exception:
community_benefits hard-depends on community_membership (a benefit is
entitled per membership tier, so the dependency is intrinsic to what it
does). community_school and community_classifieds soft-detect
event_qr_ticketing/community_membership when present and degrade
gracefully without them. community_portal soft-detects all of the above
and only renders cards for whichever are installed. This means each module
can be sold and installed on its own, or bundled as the full suite.
Local development
cd deploy
docker compose up
Odoo will be available at http://localhost:8069. The ../addons folder is
mounted read-write, so changes to module code are picked up on restart (dev
mode reload is enabled in deploy/odoo.conf).
Licensing & resellability guardrails
- Every product module is licensed
LGPL-3. - No
community_*module may depend on an Odoo Enterprise module — seeAppendix Ain the project plan for the Community-only allowlist. - No client identity (name, email, colour, price, account code) may appear
in a product module. This is enforced in CI by
scripts/check_brand_leak.py. - All client-variable behaviour is configuration data, seeded by the deployment layer, never a literal in product code.
- Every product module ships an App-Store-ready manifest, a
tests/package, and astatic/description/index.htmllisting page.
See CommunityOS_Implementation_Plan_for_Claude_Code.md for the full,
phase-by-phase build plan, and HANDOFF.md for exactly where the build
currently stands, how to resume it, and known gotchas.
CI
.github/workflows/ci.yml installs every module against Odoo 19 +
Postgres 16 with --test-enable, runs the brand-leak grep, and lints with
flake8 / pylint-odoo.
