Universal identifiers
ArkID provides standardized identifiers for the core entities of research and innovation, so each entity can be referenced, resolved, and reused consistently across systems.
Open Identity InfrastructureThe Identity Backbone of
Research and Innovation.
ArkID gives people, organizations, projects, funding, ideas, and outputs a persistent identity layer for auditable attribution, portable provenance, and interoperable research infrastructure.

Schema Definitions
What ArkID Identifies.
Durable identifiers for the full research and innovation graph. ArkID assigns standardised, resolvable hashes to six core entity types.
Ideas
Early-stage concepts, hypotheses, and innovation opportunities that need durable reference and traceability into later-stage work.
People
Researchers, founders, contributors, reviewers, and other participants across the research and innovation lifecycle.
Organizations
Universities, startups, labs, public bodies, companies, and institutes that shape research and innovation.
Projects
The formal structures through which collaboration, funding, delivery, and accountability are organized.
Funding
Calls, grants, instruments, and funding opportunities that shape what gets built and who can participate.
Outputs
Publications, datasets, software, deliverables, prototypes, and commercial products that emerge from activity.
Capabilities
What ArkID Makes Possible
A shared identity layer for the global research and innovation ecosystem
Verifiable relationships
ArkID models how those entities connect over time, including affiliations, authorship, participation, stewardship, funding, and other relationships that need to remain accountable.
Interoperability by design
ArkID is built to work with the wider ecosystem, including ORCID, ROR, DOI and DataCite, Crossref, and institutional identity systems, so identity can move across platforms instead of being trapped inside one silo.
Open and sovereign foundations
ArkID is open-source infrastructure, rooted in European governance and data protection principles, and designed to serve a global research and innovation community.
