cc-legal-tools-app

Creative Commons (CC) Legal Tools Application. This repository contains the application that manages the license tools and public domain tools (static HTML, internationalization and localization files, etc.). It consumes and generates data in the creativecommons/cc-legal-tools-data repository.

Code of Conduct

CODE_OF_CONDUCT.md:

The Creative Commons team is committed to fostering a welcoming community. This project and all other Creative Commons open source projects are governed by our Code of Conduct. Please report unacceptable behavior to [email protected] per our reporting guidelines.

About

This application manages 639 legal tools (636 licenses and 3 public domain tools). The current version of the licenses is 4.0 and includes 6 licenses. They are international and are designed to operate globally, ensuring they are robust, enforceable and easily adopted worldwide. Prior versions were adapted to specific jurisdictions ("ported"). That is why there are 636 licenses.

Broadly speaking, each legal tool consists of three layers:

1. deed: a plain language summary of the legal tool
2. legalcode: the legal tool itself
3. rdf: metadata about the legal tool in RDF/XML format

With translations of the deed and translations of the legal code, this application manages over 30,000 documents.

Not the live site

This project is not intended to serve the legal tools directly. Instead, a command line tool can be used to save all the rendered HTML and RDF/XML pages as files. Then those files are used as part of the CreativeCommons.org site (served as static files).

Setup and Usage

Once this project's required dependencies (Docker, Git, etc.) are enabled on your system, you will be able to run the legal-tools application and generate static files.

For information on learning and installing the prerequisite technologies for this project, please see Foundational technologies — Creative Commons Open Source.

Codebases Setup

Both this repository and the creativecommons/cc-legal-tools-data project repository should be cloned side by side, resulting in a structure like the following:

creative-commons/
├── cc-legal-tools-app/     (git clone of this repository)
└── cc-legal-tools-data/    (git clone of the cc-legal-tools-data repository)

To achieve this, we recommend the following procedure:

1. Create and change to a container directory, such as creative-commons or cc.

   mkdir creative-commons
   cd creative-commons

2. Clone both repos using SSH or, if that does not work, HTTPS protocol.

   git clone [email protected]:creativecommons/cc-legal-tools-app.git
   git clone [email protected]:creativecommons/cc-legal-tools-data.git

   or

   git clone https://github.com/creativecommons/cc-legal-tools-app.git
   git clone https://github.com/creativecommons/cc-legal-tools-data.git

Docker Prep and Initial Execution

Use the following instructions to prepare and run the project with Docker Compose.

1. Ensure all prerequisites and repositories are in place.
2. Ensure you are at the top level of the directory where you cloned this repository (where manage.py is).

   cd cc-legal-tools-app

3. Create Django local settings file from the example file.

   cp cc_legal_tools/settings/local.example.py cc_legal_tools/settings/local.py

   • Update variables in new file, if necessary.
   • This file is ignored by Git.
4. Build the containers.

   docker compose build

5. Run the containers.

   docker compose up

   1. app (127.0.0.1:8005): this Django application
      • Any changes made to Python will be detected and rebuilt transparently as long as the development server is running.
   2. static (127.0.0.1:8006): a static web server serving creativecommons/cc-legal-tools-data:docs/
6. Initialize data. Open a separate terminal tab, and in the same directory, run:

   ./dev/init_data.sh

   1. Deletes database (which may not yet exist)
   2. Initializes database
   3. Performs database migrations
   4. Creates supseruser (will prompt for password)
   5. Loads data

Note: Once this full setup is performed, running Step 5 above will execute the application on any subsequent occasion.

Project Usage

With the prerequisites installed and built, these tools can be used to generate and manage data from the associated data repository.

Data

The legal tools metadata is in a database. The metadata tracks which legal tools exist, their translations, their ports, and their characteristics like what they permit, require, and prohibit.

The metadata can be downloaded by visiting the URL path: 127.0.0.1:8005/licenses/metadata.yaml (currently disabled)

There are two main models (Django terminology for tables) in legal_tools/models.py:

1. LegalCode
2. Tool

A Tool can be identified by a unit (ex. by, by-nc-sa, devnations) which is a proxy for the complete set of permissions, requirements, and prohibitions; a version (ex. 4.0, 3.0), and an optional jurisdiction for ports. So we might refer to the tool by its identifier "BY 3.0 AM" which would be the 3.0 version of the BY license terms as ported to the Armenia jurisdiction. For additional information see: Legal Tools Namespace - creativecommons/cc-legal-tools-data: CC Legal Tools Data (static HTML, language files, etc.).

There are three places legal code text could be:

1. Gettext files (.po and .mo) in the creativecommons/cc-legal-tools-data repository (legal tools with full translation support):
   • 4.0 Licenses
   • CC0
2. Django template (legalcode_licenses_3.0_unported.html):
   • Unported 3.0 Licenses (English-only)
3. html field (in the LegalCode model):
   • Everything else

The text that's in gettext files can be translated via Transifex at Creative Commons localization. For additional information on the Django translation domains / Transifex resources, see How the license translation is implemented, below.

• Templates | Django documentation | Django

Translation

See docs/translation.md

Generate Static Files

Generating static files updates the static files in the docs/ directory of the creativecommons/cc-legal-tools-data repository (the Data Repository, above).

Static Files Process

This process will write the HTML files in the cc-legal-tools-data clone directory under docs/. It will not commit the changes (--nogit) and will not push any commits (--nopush is implied by --nogit).

1. Ensure the Data Repository, above, is in place
2. Ensure Docker Compose Setup, above, is complete
3. Delete the contents of the docs/ directory and then recreate/copy the static files it should contain:

   docker compose exec app ./manage.py publish -v2

Publishing Changes to Git Repo

When the site is deployed, to enable pushing and pulling the licenses data repo with GitHub, create an SSH deploy key for the cc-legal-tools-data repo with write permissions, and put the private key file (not password protected) somewhere safe (owned by www-data if on a server), and readable only by its owner (0o400). Then in settings, make TRANSLATION_REPOSITORY_DEPLOY_KEY be the full path to that deploy key file.

Development

Inside the Docker container, the Python-based tooling centers around by pre-commit and Django.

Coverage Tests and Report

The coverage tests and report are run as part of pre-commit and as a GitHub Action. To run it manually:

1. Ensure the Data Repository, above, is in place
2. Ensure Docker Compose Setup, above, is complete
3. Coverage test

   docker compose exec app coverage run manage.py test --noinput --keepdb

4. Coverage report

   docker compose exec app coverage report
