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.

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:

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

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!

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.

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 by running:

cd dev
bundle install
bin/product_taxonomy dist

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

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

In the dev/ subfolder is a simple ETL app composed of a few core models. Jekyll is used to serve the documentation locally and on GitHub pages.

• Install ruby, version matching dev/.ruby-version
• Install cue, version 0.7.x or higher
• Run cd dev && bundle install

Here are the commands you'll use most often:

cd dev

# Download dependencies
bundle install

# Commands to manage the taxonomy
bin/product-taxonomy dist     # build the dist files
bin/product-taxonomy docs     # build the documentation files
bin/product-taxonomy release  # generate a release

# Development tasks (via Rake)
bundle exec rake test              # run all tests
bundle exec rake test:unit         # run unit tests only
bundle exec rake test:integration  # run integration tests only
bundle exec rake benchmark         # run benchmarks

# Docs
bundle exec rake docs:serve        # start Jekyll server for doc microsite

# Schema validation tasks
bundle exec rake schema:vet        # validate all schemas (data and dist)
bundle exec rake schema:vet_data   # validate data schemas only
bundle exec rake schema:vet_dist   # validate distribution schemas only

We welcome contributions! Before we can merge any changes you submit via PR, you'll need to sign the Shopify CLA (a friendly robot will help when you open your first PR 🤖).

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.
