Build trusted secure fair sovereign data ecosystems with iSHARE

From the energy grids that power our cities, to the supply chains that stock our shelves, or highly quality datasets required for feeding sophisticated AI models: data is an essential resource to our societies. Unlocking the digital economy’s full potential requires large ecosystems of collaborating organisations, each contributing diverse data products. Every successful ecosystem is built on one non-negotiable: trust.

The iSHARE Foundation is a pioneering non-profit organisation behind the iSHARE Trust Framework, providing the tools data providers and data users need to verify, authenticate, and authorise exchange requests securely. Our framework keeps control exactly where it belongs – with the data owner – ensuring every exchange happens on their clear terms.

Build trusted secure fair sovereign data ecosystems with iSHARE

From the energy grids that power our cities to the supply chains that stock our shelves and the high-quality datasets that feed AI models: data is an essential resource for our societies.

Unlocking its full potential takes ecosystems of collaborating organisations, each opening its data, at the source, to the others’ services, applications and AI agents. And every successful ecosystem is built on one non-negotiable: trust.

The iSHARE Foundation is a non-profit that standardises how data rights are expressed and exercised. Building on existing open standards, the iSHARE Trust Framework aligns the functional, legal, operational and technical rules so that access granted by a data rights holder is recognised seamlessly across systems, sectors and borders — one harmonised key, for every door.

Our Impact in Action

Take a look at all ongoing projects and collaborations!

DVU

Introduction
Helps owners and tenants of large buildings like offices and schools share data about energy use. This allows better comparisons of real-world energy consumption (rather than outdated estimates), and supports the government in reaching their climate change goals, while simultaneously aiding building owners to take control of their energy consumption.

DMI

Introduction
Allows over 100 organisations to collaborate with environmental data sources on Dutch cities; optimising urban planning and mobility through data on traffic flows, heat maps, demographic information, etc. An online catalogue (PDX) allows organisations to offer and access data and services, helping organisations make better decisions related to urban environments.

DSGO

Introduction
Focuses on enhancing how data is shared across the construction industry. It brings together architects, builders, and housing organisations under agreed technical standards, helping them tackle shared challenges like housing shortages, climate resilience, and ageing infrastructure.

BDI

Introduction
This Data Space makes logistics and supply chains run more efficiently by removing common obstacles to sharing data by linking various logistics companies along six use-cases (Pharma Data Corridor, Verifiability in Agrifood Transparency, Digital Distribution Delivery Profile, Building Site Delivery Profile, The Secure Chain Container, Trusted Goods Delivery). This Data Space automates data exchanges on real-time alerts, supply chain linkages, and goods distribution.

i4Trust

Introduction
Combines open-source components and shared infrastructure to help businesses and innovation hubs build trustworthy architecture for exchanging data. This initiative makes it easier and cheaper for organisations across different industries to safely share, publish, and trade data with one another.

CEADS

Introduction
Aims to help farmers, food companies, researchers, and governments share agricultural data. It sets shared standards through a three-layer approach: a Collaboration Framework establishing governance and legal rules via a Rulebook and Code of Conduct, a Services layer delivering shared trust and interoperability services, and an Applications layer where participants build end-user tools like dashboards and farm management systems.

WEBUILD

Introduction
A European project involving over 200 organisations to build digital identity systems for businesses and individuals. Through a European Digital Identity Wallet (EUDI), paper-based processes would be replaced by secure digital wallets. This wallet will securely store credentials (Diplomas, Licences, IDs), making it easier for companies and individuals to operate across EU country borders.

GDDS

Introduction
Brings together Europe's environmental data, on biodiversity, climate, pollution, and more, into one connected ecosystem. By uniting what today sits scattered across countless separate sources, this initiative empowers researchers, governments, and businesses to collaborate more effectively on the environmental challenges that matter most.

DSSC

Introduction
A EU-funded initiative supports organisations across Europe that want to build and scale their own Data Spaces. Rather than starting from scratch alone, this project offers guidance, ready-to-use tools, and a shared vocabulary to help newcomers avoid starting from scratch, making it easier and faster to create and scale trustworthy, well-governed systems for exchanging data through commonly found best practices.

FAQs

Most frequently asked questions.

What is iSHARE?

iSHARE is a non-profit foundation, governed by its members. It sets the rules for how organisations can safely prove and control who accesses their data. iSHARE does not issue data itself, and it is not a software company, it governs the standards that make trusted data sharing possible.

Is iSHARE a software product?

No. iSHARE is not a SaaS vendor, cloud host, registry, or data platform. It governs the policy structure that others build software against. Certified partners build the tools that run on it.

What does iSHARE actually publish?

Standardised credential schemas, machine-readable usage licences, a Trusted List of certified issuers, and protocols so systems can exchange credentials safely.

Who issues the credentials and builds the software?

iSHARE does not issue credentials or write software itself. Certified Managed Service Providers issue Data Rights Credentials, and the open-source community builds the underlying code, including tools like Eclipse EDC, TRUE Connector, Amadeus DSC, and various wallets.

Is iSHARE EU-only?

No. While the framework originated in the Netherlands and is used primarily by European data sharing initiatives, our framework has global use. The specification is open and jurisdiction-neutral, with evaluations currently ongoing in Japan and the USA.
