Institutional Identity in the Scientific Ecosystem
ISNI+ combines the ISNI infrastructure with services from CCC – Ringgold Solutions to provide unique and persistent identifiers for research and development (R&D) institutions. These identifiers ensure data quality and consistency, facilitating the integration of information across different systems in the scientific ecosystem.

Consistent Registration of Institutions
The ISNI+ system uses the Identify authority table, managed by CCC – Ringgold Solutions, an organization specializing in institutional identifiers that also acts as an ISNI registration agency. With over 600,000 records, this table is widely used in the scientific ecosystem. Each R&D institution in the ISNI+ system is associated with a Ringgold identifier and an ISNI, ensuring data accuracy and consistency.
Unique Identification of Institutions in the Scientific System
THE PTCRIS It provides resources to support the adoption and management of ISNI+ identifiers, ensuring the accuracy and interoperability of institutional data within the academic and scientific ecosystem.

For data migration processes, the PTCRIS provides a data mapping service based on an open-source tool. OpenRefine. Este serviço permite encontrar os identificadores associados a uma dada instituição de I&D, facilitando a integração de dados entre diferentes sistemas.
Access to the database of R&D institutions
This service allows access to and downloads of the Identify database, managed by CCC – Ringgold Solutions. The Identify database is updated weekly with detailed information on Portuguese and foreign institutions, including ISNI+ codes and other relevant data. Data access is via FTP and can be used to access reliable, complete, and up-to-date data on institutions operating in the academic-scientific ecosystem.
Research and integration of data on R&D institutions.
Through a API, este serviço permite pesquisar instituições que operam no ecossistema académico-científico utilizando o nome da instituição ou nomes alternativos, como acrônimos, nomes antigos e variantes de idioma. Tal facilita a integração de dados autoritativos sobre instituições em sistemas externos, assegurando a interoperabilidade e a consistência.

• Production: https://api.ptcris.pt/services/resolve
• Tests: https://etl.ptcris.pt/services/resolve
parameters of API
• type — Identifier typology (e.g.: ROR, ISNI, RINGGOLD)
• id — Identifier value
The response returns all equivalent identifiers from the same organization (e.g., ROR, GRID, ISNI, Ringgold, etc.).
