Open Source Software Library

Koha is the world's first free and open-source integrated library system. Canadian public and academic libraries have been among its largest adopters and contributors, with Canadian companies providing support and development.

Axiom is a free, open-source computer algebra system with a long history. Canadian mathematicians supported through NSERC (Natural Sciences and Engineering Research Council) have contributed significantly to its formal mathematics libraries and documentation.

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.

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.

A portable development level Indy Node network, including a Ledger Browser. The Ledger Browser (for example the BC Gov's Ledger for the GreenLight Demo Application) allows a user to see the status of the nodes of a network and browse/search/filter the Ledger Transactions. von-network is being developed as part of the Verifiable Organizations Network (VON). For more information on VON see https://vonx.io. Even, better - join in with what we are doing and contribute to VON, Aries and Indy communities.

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.

This repository is a template for creating an Aries Verifiable Credential Registry (VCR) Issuer Agent. Aries VCR is the foundational technology upon which the Government of British Columbia's OrgBookBC was built. Aries VCR Issuer Controller is a starter kit for building an Aries agent that issues verifiable credentials to instances of an Aries VCR, such as OrgBookBC. This repo contains code for an issuer controller that works with Aries Cloud Agent Python (ACAPy) framework. The controller and an instance of ACA-Py can be deployed together to implement an Aries issuer agent. aries-vcr-issuer-controller was developed as part of the Verifiable Organizations Network (VON). For more information on VON, visit https://vonx.io. Even better, join in with what we are doing and contribute to VON and the Trust over IP community. Still not sure what this is? Please see this Getting started with VON overview, paying particular attention to the VON Issuer/Verifier Agent section. That's what this repo implements.

Aries Acapy Plugins is an open-source project or repository maintained by Government of Ontario in Canada.

Plugin work around inbound routing for Aries Cloud Agent Python deployments. It helps digital-trust teams operate agent networks and route messages in verifiable credential ecosystems.
