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.

The most popular tool for teams to coordinate mapping on OpenStreetMap. With this web application, an area of interest can be defined and divided up into smaller tasks that can be completed rapidly. It shows which areas need to be mapped and which areas need a review for quality assurance. You can see the tool in action: log into the widely used HOT Tasking Manager and start mapping. This is Free and Open Source Software. You are welcome to use the code and set up your own instance. The Tasking Manager has been initially designed and built by and for the Humanitarian OpenStreetMap Team, and is nowadays used by many communities and organizations.

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. The classes align with our GCDS design tokens for consistency and ease of use.

The Seed Planning and Registry (SPAR) is the Ministry of Forests' online tree seed registry. It allows users to: Order seeds or seedlings, request cone and seed processing, and seed testing Enter and update information about their seedlots, orchards, and parent trees Generate reports about seedling requests, and the seedlot inventory SPAR supports reforestation, forest and ecosystem rehabilitation and wildfire recovery. It's also designed around Climate Based Seed Transfer (CBST) to help forests adapt to climate change. SPAR guides users through the selection of suitable seedlots using the transfer rules found in the Chief Forester’s Standards for Seed Use.

An Indy Tails Server is file server that is designed to receive, store and serve Hyperledger Indy Tails files. Indy tails files are generated by an issuer of Indy AnonCred verifiable credentials when a Revocation Registry is created and must be published to a location accessible by all holders that receive a credential referenced in that Revocation Registry. The generated file is static, it does not change, and the credential holders use the tails file to produce a zero-knowledge proof of non-revocation about their credential and include it when responding to a proof request with a proof that includes claims from a revocable credential. If you are new to Indy AnonCreds Revocation, please review this document to understand how Indy revocation works, and where tails files fit in. An Indy Tails Server is a customized file server that makes it easy for AnonCred Issuers to publish tails files and for holders to access those tails files. A tails file does not have to be published to an Indy Tails Server, they can be published anywhere as long as there exists a URL accessible to all holders to access the tails file. If holders are mobile iOS or Android apps, the URL must use SSL (e.g. must be https:) due to the restrictions in those OS's. Support for publishing tails files to an Indy Tails Server is built into Aries Cloud Agent Python.
