# Tanemaki 種まき

*A local-first, decentralized app for managing and sharing traditional seeds and seedlings.*

**Tanemaki** (種まき, "to sow / scatter seeds" in Japanese; short name **Tane**, 種 "seed") helps people and collectives keep a friendly inventory of their seed bank, decide what they offer, and share it locally — without a central intermediary that could control, censor, or be fined for it. The goal is both practical and political: to support traditional seed varieties and push back against the seed monopoly.

The name honors the old Japanese mutual-aid traditions around rice — *yui* (shared community labor) and *tanomoshi* (reciprocity funds) — that inspired the paper **Plantare**, the "community currency for seed exchange" (BAH-Semillero, 2009, CC-BY-SA). Tanemaki is the digital Plantare.

## Status

Early design. See [`PLAN.md`](PLAN.md) for the full analysis and roadmap (in Spanish). The valuable prior work lives in [`docs/mockups/`](docs/mockups/).

## Principles

- **Local-first.** Works fully offline, no account, no central server. Stays useful even if no one maintains it.
- **Decentralized.** Identity is a single key you own (Duniter/Ğ1-style, with a derived subkey for transport); sharing rides on open protocols (Nostr), with optional interoperability with the Ğ1/Duniter web of trust and currency. Never a central marketplace.
- **Free/libre.** Copyleft software, open data formats, multilingual from day one.
- **Layered.** Inventory -> Offer -> Local sharing -> Web of trust. Each layer is useful on its own.

## Conventions

**English is the project language for all code.** Identifiers, class/field/column names, code comments, commit messages, branch names, and technical documents (data model, schemas) are written in English, without exception. This keeps the project contributable by anyone, anywhere.

- User-facing strings are **never hardcoded** — they go through i18n (the app itself is multilingual by design).
- Planning and discussion documents may be written in Spanish (e.g. `PLAN.md`, `docs/design/data-notes.md`); technical specs that feed code are in English (e.g. `docs/design/data-model.md`).
- Database schema changes ship as versioned Drift migrations (`drift_schemas/`), one new version per change, never editing a released version. See `docs/design/data-model.md` §5.
