Serving images on a website using Apache Solr, Diva.js and the CANTUS collection.
The status of manuscripts served by Cantus Ultimus is available here. Inclusion of additional manuscripts should be recorded there.
The repository of the Cantus Ultimus website has a submodule cantus-staticpages with the static pages of the website.
Therefore, when cloning the repository, please add the --recursive flag:
git clone https://github.com/DDMAL/cantus.git --recursive
An alternative option is to clone the repository as you normally would, and then get the submodule:
git submodule update --init
We use Docker Compose to containerize each service and keep all our dependencies in order. Cantus Ultimus is compatible with Docker Compose > 2.8.
The build process relies on environment variables specified in an .env file located at the root of the repository. A sample of this file, .env.sample, is provided.
Make a copy of .env.sample and name it .env. You must make two modifications to this file before the docker containers will build. Both POSTGRES_PASSWORD and RABBIT_PASSWORD should be uncommented and set with secure passwords.
Before launching the site, ensure that the DEVELOPMENT and DJANGO_SETTINGS_MODULE variables are set correctly. For development, DEVELOPMENT should be set to True; for deployment, it should be False. Deploying the website with DEVELOPMENT=True would leak debugging information on a live server and use Django's development server rather than gunicorn and must be avoided. DJANGO_SETTINGS_MODULE defaults to cantusdata.settings, which has the DEBUG setting set to False and does not include various debugging settings. To take advantage of those debugging applications, like django_debug_toolbar, uncomment DJANGO_SETTINGS_MODULE in the .env file and set to cantusdata.debug_settings.
When the containers are launched, a directory at ./data/postgres, will be created and mounted to the postgres container. When the POSTGRES_PASSWORD is changed between builds of the docker containers, the postgres container might run into an authentication problem because of the existing volume. If you run into that problem, make sure to remove the volume and re-launch the containers
docker rm -v <container-id>
rm -r data
In the .env.sample file, the DEVELOPMENT variable is set to False by default. For local development, set this to True in your local .env file to install development dependencies and run the development server using Django and django-extensions. For deployment on a server, this should remain set to False. You should also uncomment the DJANGO_SETTINGS_MODULE variable and set to cantusdata.debug_settings.
Windows Users: Make sure
/app/django-config.shhasLFline endings before launching. This file gets copied over into an Ubuntu container and will break the process if git automatically checked out the file using Windows (CRLF) line endings.
Execute the following commands from the root directory of the repo:
# Build the images and launch the containers (this will take a while)
$ docker compose -f compose-dev.yaml build
$ docker compose -f compose-dev.yaml up -d When testing subsequent changes, you can do this in one step by including the --build flag:
docker compose -f compose-dev.yaml up --build -d
After the build process completes, the site should be available on http://localhost:8000/ in your host machine.
By default, Cantus Ultimus works in the following way:
stateDiagram-v2
[*] --> nginx: Any request to port 8000
nginx --> StaticFile: Serve static files directly
nginx --> gunicorn: Forward webapp requests to port 8001
gunicorn --> django: Serve content from webapp
django --> postgres: Use as default database backend
django --> solr: Bind django database "signals" to solr
Python dependencies are managed with the poetry package. Although you don't necessarily need to create a local environment with these dependencies (they are installed inside the app container during the build process), it may nevertheless be useful (for example, for type checking). To do so, install poetry on your development machine and use it to install the project's dependencies into a virtual environment.
Cantus Ultimus has a few python dependencies that are for development only (for example, the code formatter black). These are located in the dev group (see the pyproject.toml file). To install these for local development, use command: poetry install --with dev.
Whenever changes are made to database models, they need to be applied to the PostgreSQL database. This occurs through Django's migrations.
If, during development, you make a change to any models, build and run the containers, as above. Then, enter the command line in the app container:
$ docker compose -f compose-dev.yaml exec -it app bashThen, run the makemigrations command:
$ python manage.py makemigrationsMigrations will then be created in the ./app/public/cantusdata/migrations/ folder. Commit these migrations and include in the pull request that includes the model changes.
You will also need to apply these migrations to the database to your development database and, once these model changes are deployed to servers, to staging, production, and any other remote databases. To apply the changes, enter the command line in the app container as before and run the migrate command:
$ python manage.py migrateNote that migrations will also need to be applied to a newly instantiated database using the migrate command.
From the Compute Canada VM, follow the same instructions as above, making sure DEVELOPMENT=False is in the .env file.
A freshly initialized instance of the website does not have an admin account or any data in the database.
A few commands will create an admin account and populate the database.
Assuming that the site has been launched and is accessible in http://localhost:8000/, fire up another terminal.
The first thing we need to do is to create an admin account for the website.
# Creating a django admin account for the website
$ docker-compose exec app python manage.py createsuperuser
Username (leave blank to use 'root'):
Email address:
Password:
Password (again):
Superuser created successfully.Using your admin credentials, verify that you are able to log into the admin django site, which should be located at /admin/.
When initializing the site, remember to apply migrations to the database (see the "Database Migrations" section above).
When navigating through any of the tables in the admin interface (e.g., Manuscripts, and Chants), they will appear to be empty.
We can populate the Manuscripts and Chants from the information available in the Cantus Database.
The scripts to populate the database are included in the repository. Head back to the terminal where you created the admin user account.
Import the manuscripts and chants
# Import the manuscripts
$ docker-compose exec app python manage.py import_data manuscripts
Deleting old manuscripts data...
Starting manuscript import process.
# It should take about 5 minutes to import the data.
Successfully imported 155 manuscripts into database.
Waiting for Solr to finish...
Done.
# Import the IIIF manifest urls
$ docker-compose exec app python manage.py import_data iiif
Deleting old iiif data...
Waiting for Solr to finish...
Done.An additional command is included to import chants associated with a specific manuscript
$ docker-compose exec app python manage.py import_data chants --manuscript-id MANUSCRIPT_IDThis process can also be done using the user interface (recommended; see below).
Once the manuscript information has been fetched from the Cantus Database, additionally to the Manuscript's metadata, the following fields become available:
(Paris, F-Pnm lat. 15181)
- The cantus URL
- The cantus CSV export URL, which contains all chant/folio associations for this manuscript
The process for turning any Manuscript in the initialized database into a searchable Manuscript in the Cantus Ultimus interface involves the following steps:
- Importing all the chant information of the manuscript
- Defining the source images of the Manuscript through a IIIF Manifest file
- Setting the Manuscript as a
publicManuscript in the Cantus Ultimus interface - Map the folio information from Cantus Database to the images obtained from the IIIF Manifest
In the admin interface (located in http://localhost:8000/admin), navigate the list of Manuscripts and select the one you wish to enable in Cantus Ultimus.
Select the manuscript by ticking its corresponding check box.
In the Actions menu located at the top, trigger the action called Import the chants associated with the selected manuscript(s).
This will trigger a series of queries in the backend. Wait until you see the notification Loaded chants for manuscript above the Actions menu. It may take a few minutes for this process to complete.
After refreshing the admin page and looking at the Manuscript in the list, it should appear with the flag Chants loaded enabled. This indicates that the chant information has been added to the database and solr index.
Of all the manuscripts in the list displayed in the admin interface, only a handful have a public IIIF Manifest with source images.
IIIF Manifest files can be found within libraries such as Gallica, e-codices, and others.
A list of known manifests is maintained in app/public/data_dumps/manifests.csv and is automatically applied to the database by running import_data iiif. When a IIIF Manifest is located for a specific manuscript, the URL can be included in the manuscript's metadata manually:
Click on the Manuscript's entry.
Introduce the IIIF Manifest URL under the Manifest url field.
Save the changes.
Making a manuscript a public manuscript indicates to the Cantus Ultimus website that the manuscript should show up under the Manuscript tab of the final user's web interface.
Click on the Manuscript's entry.
Tick the public value.
Save the changes.
Once the chant information and IIIF manifest url have been added to a Manuscript, and the manuscript has been marked as public, the mapping tool becomes available to map the images with the folio metadata.
The mapping tool is located in the following address: http://localhost:8000/admin/map_folios
Within the mapping tool, the new manuscript should appear with an option to Map now.
Click on Map now.
The mapping tool triggers a heuristic search on the background, which tries to map the images in the IIIF Manifest to the folios described in the Cantus Database.
The result of that automatic process will be displayed in the mapping interface.
At this point, the user might want to verify that the information provided by the automatic mapping is accurate, and correct it when it is not.
In the mapping interface, green folio pages indicate a folio has been mapped to an image manifest, whereas a red folio page indicates that a folio has not been mapped to an image from the manifest.
Once the mapping process has been manually revised, conclude the mapping process by clicking on Submit this Mapping.
It may take several minutes for the backend of the website to deploy the changes across the database and solr index.
The user will be able to know when that process has concluded by revisiting the admin interface. A complete mapping process will activate the Is mapped flag in the corresponding manuscript.
At this point, the manuscript should be searchable within the main website.
To add OMR search functionality to a manuscript, a set of MEI 5 files for the manuscript needs to be added to the production MEI files repository. Add these files in a folder named with the Cantus Database source ID for the manuscript. The mei files must be named by the following convention: *_[folio_number].mei. Once these are committed to the main branch of the production MEI files repo, they can be pulled with the rest of the Cantus Ultimus code base (the production MEI files repository is a submodule of the CU repo).
In the running app container, run the index_manuscript_mei command with the first command line argument being the source ID of the manuscript. Additional command line options can be found in that command's help text. Once this command has completed, the manuscript MEI has been indexed in Solr.
Go to the Cantus Ultimus admin page and ensure that the "Neume Search" and "Pitch Search" plugins exist in the database. If they do not, simply create new plugins with those names. Then, find the manuscript whose MEI you are adding in the admin panel. On that manuscript's admin page, select either the "Neume Search" plugin (if the manuscript's neumes are unpitched) or both the "Neume Search" and "Pitch Search" plugin (if the manuscript's neumes are pitched). Save the manuscript form.
When you navigate to that manuscript's detail view, OMR search should be available in the search panel.
