NI4OS Core Services

NI4OS-Europe Login supports two authentication and authorisation protocols that you can choose from:  OpenID Connect - an extension to OAuth 2.0 and Security Assertion Markup Language (SAML) 2.0

Services can be connected to NI4OS-Europe Login using OpenID Connect (OIDC). You need to install an OpenID Connect Relying Party (OIDC RP) software and integrate it into your application.

To enable federated access to a web-based application, you can connect to the SAML Identity Provider (IdP) interface of NI4OS-Europe Login as a SAML Service Provider (SP).

A Virtual Organisation (VO) is a group of users. VOs are created to group researchers who aim to share resources and access services to achieve a common goal as part of a scientific collaboration. VOs can also be organised in a hierarchical structure for creating groups or subgroups within a VO.

Groups within a VO can only be created by NI4OS-Europe Login platform administrators. Please contact aai-support@ni4os.eu indicating the following information for every (sub)group that you need to add/remove to/from your VO.

User's Affiliation to a VO, as defined in RFC4512, has eight permissible values. These are faculty, student, staff, alum, member, affiliate, employee, library-walk-in. The NI4OS-Europe Login Registry assigns to all users the “member” affiliation by default, during the VO(COU) enrollment process.

VO membership expires within a given time, typically a year after the VO member joins the VO. VO members receive a notification with the subject "vo.example.org membership will expire soon" warning them that their membership will expire four weeks before expiration. The notification email is sent on a weekly basis and includes all the instructions needed by VO members in order to reapply for a membership.
