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

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.

BC Sans (2.0) is an open-source "living" typeface developed for government to improve the readability and delivery of digital services. It was designed to support special characters and syllabics found in Indigenous Languages in B.C.

The Digital Marketplace is a web application that administers British Columbia's Code With Us and Sprint With Us procurement programs. It enables (1) public sector employees to create and publish procurement opportunities, and (2) vendors to submit proposals to these opportunities.

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.

Database schema documentation tooling used in B.C. government projects.

An Open511 validator and converter

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]

Shared API for binary quadratic models and samplers in D-Wave Ocean.

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.

minorminer is a heuristic tool for minor embedding: given a minor and target graph, it tries to find a mapping that embeds the minor into the target.

Jupyter Book is an open-source tool for building publication-quality books and documents from computational material. Jupyter Book allows users to write their content in Markdown files or Jupyter notebooks, include computational elements (e.g., code cells) in either type, include rich syntax such as citations, cross-references, and numbered equations, and using a simple command, run the embedded code cells, cache the outputs and convert this content into: a web-based interactive book and a publication-quality PDF.

The Littlest JupyterHub (TLJH) distribution helps you provide Jupyter Notebooks to 1-100 users on a single server. The primary audience are people who do not consider themselves 'system administrators' but would like to provide hosted Jupyter Notebooks for their students or users. All users are provided with the same environment, and administrators can easily install libraries into this environment without any specialized knowledge.

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.
