We are pleased to announce today's start of the Integration Phase of the Jupyter4NFDI basic service project under the umbrella of #Base4NFDI. Apart from scaling up the Jupyter service itself, this two year phase is devoted to establish new and intensify existing connections to other basic services, disciplinary consortia, resource providers and end users. Inspired by #IAM4NFDI, these connections will be implemented by incubator projects. Watch out for upcoming calls!
