NgREN PID (ARK) Policy

NgREN PID (ARK) Policy — Scope, Governance, and Persistence

The policy focuses on the following among others:

  • Unique identifier assignment (via ARKs)
  • Long-term resolution via NgREN resolver
  • Versioning and redirection guidelines
  • Institutional governance and sustainability

 

1. Scope and eligibility
NgREN manages ARKs for eligible Nigerian universities, polytechnics, colleges, research centres, and cultural heritage organizations participating in the NgREN federation.

2. Naming & assignment

  • Each participating organization may receive a dedicated namespace under NgREN’s NAAN or its own NAAN from ARK Alliance where applicable.

  • Local naming is delegated to the institution following NgREN guidelines on uniqueness and stability.

3. Metadata requirements
Every ARK must have minimal descriptive metadata:

  • Title

  • Creator/Responsible unit

  • Resource type (e.g., thesis, dataset)

  • Landing/target URL

  • Owning institution

  • Date of issuance (minted)

4. Persistence commitment
NgREN commits to maintain the resolver and core services, including:

  • Persistent resolution of ARKs under our stewardship

  • Reasonable efforts to update targets when locations change

  • Maintaining service continuity during infrastructure upgrades

5. Versioning and changes

  • Where resources are versioned, qualifiers or new ARKs may be assigned.

  • Substantive changes to a resource may require a new ARK to preserve citation integrity.

6. Takedowns and redirects

  • Requests for takedown or access restrictions are handled by the owning institution following legal and ethical guidelines.

  • ARKs may resolve to metadata/notice pages if access is restricted.

7. Service levels (fill in your targets)

  • Uptime target: [e.g., 99.5% annually]

  • Support response: [e.g., 2 business days]

  • Change notifications posted on Service Status page.

8. Governance and contact

  • NgREN PID Service is managed by NgREN Technical department.
