Drupal distribution built around WET-BOEW for accessible multilingual government websites.

This project was designed to integrate with Statistic Canada’s The Zone platform. In The Zone, users can create individual workspaces with Kubeflow Notebooks. To persist their work, users can attach volumes to their notebooks. These volumes are not automatically deleted when a notebook is deleted. Users are free to move them or to reuse them. As a result, over time, users tend to amass several unused volumes. These volumes sit on the cloud and result in unnecessary costs. The purpose of this project is to design an automatic system that detects these unused volumes and safely removes them, reducing unnecessary expenditure. Despite being primarily designed for Statistics Canada, this project strongly values open-source practices. The codebase is available for public use and the entire development process is documented on the issues page. The volume cleaner was designed to have as little coupling as possible so it can easily integrate into projects outside Statistics Canada. Using open-source and being open-source was an important development philosophy.

Open Data is structured data (data with a pattern that makes it easy to search and use) that is machine-readable, freely shared, used and built on without restrictions.

This Directive outlines requirements for ministries and provincial agencies on listing all data inventories, publishing open data, and preparing information systems to support ongoing open data requirements. The open data initiative supports government efficiency, effectiveness and innovation. Faster and easier access to government data through a one-window data portal facilitates evidence-based policy, informs service delivery and promotes greater transparency and accountability. The open data initiative also supports public engagement and participation by allowing Ontarians to develop their own analysis, insights, and digital products. To support this implementation of the directive, an Open Data Guidebook is available as a tool and resource to Ontario ministries and provincial agencies. The Open Data Directive is a Management Board of Cabinet Directive, issued under the Management Board of Cabinet Act.

Aries Verifiable Credentials Registry (VCR), part of the Hyperledger Aries family of Digital Trust technologies, provides a searchable public directory based on Verifiable Credentials (VCs). It was historically known as both OrgBook (which is actually a deployment of Aries VCR) and Indy Catalyst. Aries VCR is actively developed by the British Columbia Government’s Digital Trust Team in Canada, and the most well-known live example is OrgBook BC. In an instance of Aries VCR, credentials can be issued from a variety of authorities about subjects in the instance. A core set of credentials are issued by an authority responsible for “creating” the subject. Other credentials can then be issued against the subject of these core credentials. All credentials are stored in a secure digital wallet and accessed via its website or the public API. This means an instance of Aries VCR can be an authoritative public registry of any referenceable information.

Shared form service for hosted public-sector forms.

Users interact with D‑Wave quantum computers through a web user interface (UI), and through open-source tools that communicate with the Solver API (SAPI). The SAPI components are responsible for user interaction, user authentication, and work scheduling. In turn, SAPI connects to back-end servers that send problems to and return results from QPUs and additional solvers, which are located in different geographical regions (for example, North America or Europe).[1]

GC Design System Tokens are the smallest building blocks of the design system. They represent design decisions for basic elements like colour, typography, and spacing, creating a curated set of options that we base our designs on. Tokens replace hard-coded values with variables that can be reused throughout the entire code base which makes it easier to maintain and update any code. Our tokens help us create a consistent visual experience that meets the Government of Canada requirements. They also improve communication between design and development by establishing a shared language.

CSS Shortcuts is a CSS utility framework built to match GC Design System (GCDS) styles and Canada.ca standards. It provides predefined CSS utility classes that apply core design elements, like colours, spacing, and typography, to your HTML.
