euCanSHare. Deliverable D2.2 - Data distribution protocols and interfaces

This document reviews the efforts dedicated to the development and implementation of interoperability channels among euCanSHare components, as well as the creation of uniformed connections with external consumers and services. A common OIDC-based euCanSHare-ID service is put in place to wrap in key eucanSHare platform components (section 3.1). A network of epidemiological databases is feeding the euCanSHare catalogue enabling multi-cohort harmonization studies, even in a federated manner (section 3.2). Additionally, European Genome-Phenome Archive (EGA) and Euro-Bioimaging (EuBi) are leveraged into the platform as permanent data repositories for omics and bioimaging datasets respectively (section 2.1). They provide efficient data distribution channels within euCanSHare by means of robust streaming REST APIs, or more complex systems like user-specific FUSE-enabled remote access to encrypted files over SFTP (section 3.3). Like that, euCanSHare modules as the analysis portal are able to offer researchers an integrated view of the repository’s datasets, both public and protected, together with analysis tools and pipelines (section 3.3.3). For that, repositories’ native authentication/authorization mechanisms are employed, which represents a challenge for achieving a complete integration of the system’s components, and therefore, further developments are being carried out in the euCanSHare scope in order to offer a common and standardized way for accessing data (section 4.).
