Welcome to Arches Lingo!

Arches Lingo is an Arches application designed to support the creation of thesaurus/vocabulary data. It supports the creation of polyhierarchical thesauri, and provides a user interface for managing thesauri and their terms. Arches Lingo is built on top of the Arches platform, which is an open-source software platform for managing cultural heritage data.

Please see the project page for more information on the Arches project.

Installation

If you are installing Arches Lingo for the first time, we strongly recommend that you install it as an Arches application into a existing (or new) project. Running Arches Lingo as a standalone project can provide some convenience if you are a developer contributing to the Arches Lingo project but you risk conflicts when upgrading to the next version of Arches Lingo.

Install Arches Lingo using the following command:

pip install arches-lingo

For developer install instructions, see the Developer Setup section below.

Project Configuration

1. If you don't already have an Arches project, you'll need to create one by following the instructions in the Arches documentation.

2. When your project is ready, add "arches_querysets", "arches_vue_components", "arches_controlled_lists", "arches_lingo", and "pgtrigger" to INSTALLED_APPS below the name of your project:

   INSTALLED_APPS = (
       ...
       "my_project_name",
       "arches_querysets",
       "arches_vue_components",
       "arches_controlled_lists",
       "arches_lingo",
   )
   

3. Make sure the following settings are added to your project

   REFERENCES_INDEX_NAME = "references"
   ELASTICSEARCH_CUSTOM_INDEXES = [
       {
           "module": "arches_controlled_lists.search_indexes.reference_index.ReferenceIndex",
           "name": REFERENCES_INDEX_NAME,
           "should_update_asynchronously": True,
       }
   ]
   TERM_SEARCH_TYPES = [
       {
           "type": "term",
           "label": _("Term Matches"),
           "key": "terms",
           "module": "arches.app.search.search_term.TermSearch",
       },
       {
           "type": "concept",
           "label": _("Concepts"),
           "key": "concepts",
           "module": "arches.app.search.concept_search.ConceptSearch",
       },
       {
           "type": "reference",
           "label": _("References"),
           "key": REFERENCES_INDEX_NAME,
           "module": "arches_controlled_lists.search_indexes.reference_index.ReferenceIndex",
       },
   ]
   
   ES_MAPPING_MODIFIER_CLASSES = [
       "arches_controlled_lists.search.references_es_mapping_modifier.ReferencesEsMappingModifier"
   ]
   

   Note: the should_update_asynchronously: True setting requires Celery to be running. See the Arches documentation for instructions on configuring and running Celery.

4. Optionally, enable anonymous (read-only) access by adding the following setting to your project's settings.py or settings_local.py:

   LINGO_ALLOW_ANONYMOUS_ACCESS = True
   

   When enabled, unauthenticated users can browse schemes, concepts, and search results in a read-only mode. When disabled (the default), all users must log in to access any Lingo content. Authenticated users who are not members of the "Lingo Editor" group will still see a read-only experience regardless of this setting.

5. Next ensure arches, arches-vue-components, and arches_lingo are included as dependencies in package.json

   "dependencies": {
       "arches": "archesproject/arches#stable/8.1.4",
       "arches-vue-components": "archesproject/arches-vue-components#stable/2.0.2",
       "arches_lingo": "archesproject/arches-lingo#stable/1.1.1"
   }
   

6. Update urls.py to include the arches_lingo urls

   urlpatterns = [
       path("", include("arches_lingo.urls")),
   ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
   

7. Configure language support

   Arches Lingo uses cookie-based language switching (via Django's django_language cookie) rather than URL-based language prefixes. If you are running Lingo as a standalone project, ensure the following are set in your project settings:

   MIDDLEWARE = [
       ...
       "django.middleware.locale.LocaleMiddleware",
       ...
   ]
   
   LANGUAGES = [
       ("en", "English"),
       # Add other languages your deployment supports, e.g.:
       # ("es", "Spanish"),
       # ("de", "German"),
   ]
   

   The LANGUAGES setting determines which languages appear in the Lingo language selector. The django_language cookie persists the user's language choice across sessions.

   If you are using the language switcher, you will want to remove the following lines from near the bottom of your urls.py file as they will break language switching in Lingo:

   if settings.SHOW_LANGUAGE_SWITCH is True:
       urlpatterns = i18n_patterns(*urlpatterns)
   

8. Install the arches application package (models and other data)

   python manage.py packages -o load_package -a arches_lingo --yes
   

9. Install and build front-end dependencies. Navigate to your project's app directory (the one with package.json) and run:

   npm install
   npm run build_development
   

10. Start your project:

    python manage.py runserver
    

Developer Setup (for contributing to the Arches Lingo project)

1. Download the arches-lingo repo:

   a. If using the Github CLI: gh repo clone archesproject/arches-lingo

   b. If not using the Github CLI: git clone https://github.com/archesproject/arches-lingo.git

2. Download the arches package:

   a. If using the Github CLI: gh repo clone archesproject/arches

   b. If not using the Github CLI: git clone https://github.com/archesproject/arches.git

3. Create a virtual environment outside of both repositories:

   python3 -m venv ENV
   

4. Activate the virtual environment in your terminal:

   source ENV/bin/activate
   

5. Navigate to the arches-lingo directory, and install the project (with development dependencies):

   cd arches-lingo
   pip install -e . --group dev
   

   Note: --group dev requires pip >= 25.0. If you have an older pip, upgrade first with pip install --upgrade pip.

6. Also install core arches for local development:

   pip install -e ../arches
   

7. Create a settings_local.py file with DEBUG=True:

   echo "DEBUG = True" > arches_lingo/settings_local.py
   

8. Run the Django server:

   python manage.py runserver
   

9. (From the arches-lingo top-level directory) install the frontend dependencies:

   npm install
   

10. Once the dependencies have been installed, generate the static asset bundle:

    a. If you're planning on editing HTML/CSS/JavaScript files, run npm start. This will start a development server that will automatically detect changes to static assets and rebuild the bundle.

    b. If you're not planning on editing HTML/CSS/JavaScript files, run npm run build_development

11. If you ran npm start in the previous step, you will need to open a new terminal window and activate the virtual environment in the new terminal window. If you ran npm run build_development then you can skip this step.

12. Install the ontologies, branches, and resource models from the package.

    python manage.py setup_db
    python manage.py packages -o load_package -a arches_lingo --yes -db
    

13. Load the test data:

    python manage.py loaddata tests/fixtures/data/FISH_Example_Thesauri.json.xz
    

14. In the terminal window that is running the Django server, halt the server and restart it.

    (ctrl+c to halt the server)
    python manage.py runserver
    

Committing changes

NOTE: Changes are committed to the arches-lingo repository.

1. Navigate to the repository

   cd arches-lingo
   

2. Cut a new git branch

   git checkout origin/main -b my-descriptive-branch-name
   

3. If updating models or branches

   1. Manually export the model or branch from the project
   2. Manually move the exported model or branch into one of the subdirectories in the arches-lingo/arches_lingo/pkg/graphs directory.

4. Add your changes to the current git commit

   git status
   git add -- path/to/file path/to/second/file
   git commit -m "Descriptive commit message"
   

5. Update the remote repository with your commits:

   git push origin HEAD
   

6. Navigate to https://github.com/archesproject/arches-lingo/pulls to see and commit the pull request
