📚 The Taxonomy

Our taxonomy is an open-source comprehensive, global standard for product classification. It's a universal language that empowers merchants to categorize their products. Spanning 25+ essential verticals, our taxonomy encompasses categories, attributes, and values, all thoughtfully integrated within Shopify and numerous marketplaces.

🧭 Getting started

This repository is the home of Shopify's Standard Product Taxonomy. It houses the source-of-truth data, the distribution files for implementation, and the source code that makes this all sing.

You can think of this repository serving 3 primary users:

Integrators: Those who integrate the taxonomy into other systems. You want stable distribution files.
Taxonomists: Those who want to evolve the taxonomy itself. Submit a change request or work directly with the source-of-truth data files themselves.
Developers: Those who want to evolve how this ETL pipeline works, or add richer tooling for other users. You work with the application files.

🧩 1. Integrators: How to integrate with the taxonomy

Dive straight into dist to find the files you need and integrate this taxonomy into your system.

We offer txt and json formats to make it easy to integrate with your systems. If you have a specific format you'd like to see, please open an issue and let us know!

🗺️ Mapping to other taxonomies

To make it easier to integrate with the taxonomy, we have also included a set of data called mappings. These are rules that can be used to convert between categories and attributes in the Shopify taxonomy to categories and attributes of another taxonomy. For more on mappings see documentaton in the integrations directory.

🧑🏼‍🏫 2. Taxonomists: How to make changes to the taxonomy

Submit a taxonomy tree change request to give us insight and evolve the taxonomy. This is the simplest way to effect change.

Alternatively, you may submit PRs directly yourself against the source-of-truth files in data/.

If you make changes to any files in data/, you'll need to update the distribution files. There are two ways:

Make a PR comment of /generate_dist to have CI commit the changes for you 🤖
Run make locally and commit the changes yourself

🌐 Localization to other languages

Our taxonomy supports translations to various languages in the localizations directory. To report a translation issue (non-English text), submit a localization fix request.

👩🏼‍💻 3. Developers: How to evolve the system

Everything else is how we manage the taxonomy and generate distributions. This is where the magic happens.

This is a simple ETL app composed of a few core models. The app is built on Rails and Jekyll:

Rails is used to generate distribution files from data/ and ensure the correctness of results.
Jekyll is used to serve the documentation locally and on GitHub pages.

🛠️ Setup and dependencies

For Shopify employees or folks with minidev:

Run dev up

For everyone else you'll need to:

Install ruby, version matching .ruby-version
Install cue, version 0.7.x or higher
Install make
Run bundle install

⛰️ Common tasks

Here are the commands you'll use most often:

make [build]  # build the dist and documentation files
make clean    # remove sentinels and generated files
make seed     # parse data/ into local db
make console  # irb with dependencies loaded
make test     # run ruby tests and cue schema verification
make run_docs # http://localhost:4000 interactive view of dist/

If you want to add a new distribution format, you'll need to do 3 things:

Add new serialization methods to relevant models (e.g., Category#as_json, Category#as_pkl)
Extend bin/generate_dist to write files in the new format
Extend the Makefile to add the new file format to the clean target

📂 Navigating this repository

├── db/
│   ├── schema.rb        # because this is a local-only app, we don't use migrations
│   └── seed.rb          # a custom seed script to load data/ into the local db

📅 Releases

You can always find the current published version in VERSION. The changelog is available in CHANGELOG.md.

Versions are determined by CalVer, in sync with Shopify's API release schedule.

That means a stable release every 3 months at most, at the beginning of the quarter. Version names are date-based to be meaningful and semantically unambiguous (for example, 2024-07).

Formal releases are published as Github releases and available on the interactive docs site.
