Open Source Software Library

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.

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.

dwave-system is an API for easily incorporating D-Wave quantum computers as a sampler in the Ocean software stack, directly or through the Leap service’s cloud-based hybrid solvers. It includes DWaveSampler, a dimod sampler that accepts and passes system parameters such as system identification and authentication down the stack, StrideHybridSolver, for Leap’s Stride™ hybrid solver, and others. It also includes several useful composites—layers of pre- and post-processing—that can be used with DWaveSampler to handle minor-embedding, optimize chain strength, etc.
