BIG-MAP Application Registry

This repository contains the source code of the official app registry for the BIG-MAP project.

Adding an app to the registry

All apps that are part of this registry, must adhere to the following requirements (required by the European Commission):

• The app's hosted source code repository (e.g., on GitHub) is publicly accessible.
• The repository specifies the app's open-source license (e.g., in license.txt). You can find a list of approved open-source licenses here.
• The repository makes suitable acknowledgment to the funding by the European Commission using the following exact phrasing (e.g., in README.txt):

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 957189. The project is part of BATTERY 2030+, the large-scale European research initiative for inventing the sustainable batteries of the future.

• The repository provides sufficient technical documentation on how to install and run the software. This can be achieved via a README file, a Wiki page, or a software documentation hosting platform such as Read The Docs. Please pay particular attention to this, since it is a criterion the evaluators will use to test the apps.

• Two videos, maximum length 4 minutes, showing the installation and demonstration of your app, refer to point 4 for details.

Feel free to propose a new app category to be added to category.yaml before adding your app.

Apps are added to the registry by adding an entry to the apps.yaml file within this repository.

1. Create a pull request to this repository that adds a new entry to the apps.yaml file, e.g., by editing the file directly in the browser. Example:

   my-big-map-app:
   git_url: https://github.com/big-map/mybigmapapp.git
     metadata:
       title: My BIG-MAP app
       description: |
           My BIG-MAP app helps to promote accelerated discovery
           of novel battery materials.
       authors: A. Doe, B. Doe

       external_url: http://my-app.example.com
       documentation_url: https://my-big-map-app.readthedocs.io
       logo: https://github.com/my-org/my-big-map-app/raw/main/logo.png
       state: development
       version: '1.1'
     categories:
       - technology-aiida
       - technology-ase
       - quantum
       - WP9

   Note: To check which fields are optional, refer to the valid keys subsection; but it is highly encouraged to fill in all the fields to process your PR quickly. The categories field must contain at least one item.

2. Your app will show up in the BIG-MAP App Store once your pull request is approved and merged.

3. NOTE: It is important that you mention your name (along with your email id), the name of your PI and the BIG-MAP partner institute in the PR. This helps us keep track of who is making the contribution and whom to contact for future updates/news.

4. To facilitate the review process of your apps, it is required that you make two videos (maximum lenght 4 minutes, each) showing:

• the app running under working conditions and being used, starting with a short (30 second) explanation of the goal of the app and what problem it is trying to solve
• how the app can be downloaded, installed, and put in working condition, with clear and concise instructions for each step

5. To share these videos get in touch with the maintainers of this repository.

Tip: The App Store supports the $ref syntax to reference externally hosted documents. That means you can reference metadata that is hosted at a different location, which makes it easier to dynamically update it. For example, if you place a metadata.yaml file within your app repository, then you can reference that file in the App Store like this:

my-big-map-app:
  metadata:
    $ref: https://github.com/my-org/my-big-map-app/raw/main/metadata.yaml
  categories:
    - technology-aiida
    - technology-ase
    - quantum
    - WP9

You can even reference only parts of the metadata, example:

my-big-map-app:
  metadata:
    title: MyBIG-MAP app
    description:
      $ref: https://github.com/my-org/my-big-map-app/raw/main/metadata.yaml#description
  categories:
    - technology-aiida
    - technology-ase
    - quantum
    - WP9

The App Store will assume that external references are in JSON format unless the referenced path ends with .yaml or .yml.

Valid keys for app entries in apps.yaml

Key	Requirement	Description
metadata	Mandatory	General description of the app (see below).
categories	Mandatory	An array of categories, where each category must be one of the categories specified in categories.yaml.
git_url	Mandatory	Link to the source code, can be github or gitlab or any other publicly available repository.

Valid keys for app metadata

Key	Requirement	Description
title	Mandatory	The title will be displayed in the list of apps in the application manager.
description	Mandatory	The description will be displayed on the detail page of your app.
authors	Mandatory	Comma-separated list of authors.
affiliations	Mandatory	Single university/institution name or a comma-separted list of institutes in case of multiple affiliations.
documentation_url	Mandatory	The link to the online documentation of the app (e.g. on Read The Docs).
video_installation_url	Mandatory	A video of maximum length of 4 minutes showing how the app can be downloaded, installed, and put in working conditions.
video_demonstration_url	Mandatory	A video of maximum length of 4 minutes showing the app running under working conditions and being used, starting with a short explanation of the goal of the app and what it is trying to solve.
external_url	Optional	General homepage for your app.
logo	Optional	Url to a logo file (png or jpg).
state	Optional	One of - registered: lowest level - app may not yet be in a working state. Use this to secure a specific name. - development: app is under active development, expect the occasional bug. - stable: app can be used in production.
industrial_collaboration	Optional	If you have a closed-source app and you are an industrial partner of BIG-MAP.

Information for maintainers

To prepare a development environment, please run the following steps:

$ pip install -r src/requirements.txt -r tests/requirements.txt
$ pre-commit install

This will install all requirements needed to run the git pre-commit hooks (linters), build the website locally, and execute the test framework.

To execute tests, run:

$ PYTHONPATH=src pytest

Executed tests include unit, integration, and validation tests. The validation tests check the validity of all schema files, the data files e.g. apps.yaml and categories.yaml, and – if present – the configuration file (config.yaml).

To generate the website, simply execute the following script:

$ python src/build.py

The continuous-integration workflow is implemented with GitHub actions, which runs the pre-commit hooks, unit, integration, and validation tests. In addition, all commits on the main branch are automatically deployed to GitHub pages.
