The DPP Vocabulary Hub is the semantic repository for creating, managing, and publishing semantic data models (DPP templates) for Digital Product Passports. It provides a central repository of publishing and reusable vocabularies and ontologies, enabling stakeholders to align on a shared data structure, meaning, and rules, and to generate implementation-ready formats such as JSON Schema, JSON-LD or APIs.

GS1 Resolver is a free and open-source web-server application that allows you to resolve GS1 identifiers to their corresponding web resources. This is really useful for products, services, and other entities that have a GS1 identifier stored in a GS1 Digital Link QR Code. In simple terms, a consumer scans the GS1 Digital Link QR Code on your product, and GS1 Resolver will redirect them to the correct page on your website, all without having to change your existing web applications or databases. You simply add the GS1 identifier and the corresponding target URL to the Resolver database.
Add authentication to applications and secure services with minimum effort. No need to deal with storing users or authenticating users.

Veridian Wallet is an open source application developed by the Cardano Foundation. This project is the result of on-going research and development pertaining to the principles of Self-Sovereign Identity (SSI), Self-Certifying Identifiers (SCIs), Verifiable Data Registries (VDRs), and the standards, frameworks, and implementations available within the Cardano ecosystem and externally. The first release of the wallet provides an open source implementation demonstrating the Key Event Receipt Infrastructure (KERI) on Cardano. This wallet has undergone security auditing and penetration testing, and mitigations have been applied.
