Use Case Collaboration Groups

  • Use Case 1: Peer review of repository-based resources
  • Use Case 2: Endorsement of repository-based resources (e.g. overlay journals, endorsement services)
  • Use Case 3: Integration of reviews/endorsements with downstream services
Project Overview

Our current research and social context – the coronavirus pandemic, economic upheaval, climate change, racial injustice – requires timely and reliable research results, shared by, and with, all parts of the world.

On January 28, 2021, COAR launched the Notify: Repository and Services Interoperability Project.  The aim of this project is to develop a standard and interoperable approach that will link reviews and endorsements from different services with the research outputs housed in the distributed network of preprint servers, archives, and repositories.

COAR has already developed a proposed model for (bi-directionally) linking resources held in repositories with related resources held in networked services using a distributed, message-oriented approach based on W3C Linked Data Notifications (LDN). The COAR model is described and illustrated in Modelling Overlay Peer Review Processes with Linked Data Notifications.

This project involves working with implementing partners to:

  1. Aid the development of reference implementations of the identified use-cases involving repositories and networked services
  2. Support high-level collaboration to align development in the different implementation projects
  3. Support and encourage broad interoperability by establishing common practices, community norms and conventions
  4. Engage with relevant development communities (e.g. for important repository and service platforms) to gain support with implementation.

The results of this work will be shared widely with the community so that the technologies and conventions can be adopted by all interested repositories and services.

It should be noted that, although this project is focusing on the peer review use case, these technologies can be used to support a wide variety of interactions between repositories and value added services.


Project Deliverables
  • A testing platform to allow implementations to be tested for functionality and standards-compliance
  • Community conventions
    • Agreements on use-case scenarios to be supported
    • Agreements on simple payload structures and vocabularies to support the use-case scenarios
  • Shared knowledge-base and guidance material relating to technical implementation
