What ArkID Makes Possible

ArkID is open identity infrastructure for research and innovation. It gives ideas, people, organizations, projects, funding, outputs, and products a durable identity, and makes the relationships between them traceable over time.

Built on open standards and designed for interoperability, ArkID helps research and innovation systems move from fragmented records to accountable, connected infrastructure.

What ArkID identifies

Durable Identifiers for the Full Research and Innovation Graph

ArkID assigns standardized, resolvable identifiers to six core entity types.

Ideas

Early-stage concepts, hypotheses, and innovation opportunities that need durable reference and traceability into later-stage work.

Relationships and traceability

How ArkID Connects the Research and Innovation Graph

Relationship model

ArkID models affiliations, authorship, participation, stewardship, funding, and other relationships between entities, so the full picture of research and innovation activity remains traceable.

Time-aware connections

Relationships carry temporal context, making it possible to track how affiliations, roles, and connections evolve over the lifecycle of a project or organization.

Complete provenance

Every path from an early-stage idea through funding, projects, and contributors to final outputs can be traced and verified, with identity claims grounded in resolvable, stable references.

Every ArkID resolves to a public URL, giving each entity a stable, human-readable reference point across systems and over time.

Interoperability

Built to Work Alongside Systems You Already Use

ArkID is designed to sit alongside existing identifiers, not replace them.

External identifier registries

ArkID integrates with the identifier systems research and innovation teams already rely on, so identity can move across platforms rather than being duplicated or lost.

API and integration surfaces

REST and GraphQL APIs, JSON Schema validation, ETL pipelines, and SDK support give developers the surfaces needed to integrate ArkID into existing workflows and platforms.
