The EUDAT Collaborative Data Infrastructure

About

EUDAT offers heterogeneous research data management services and storage resources, supporting multiple research communities, through its network of academic computing and data centres across 15 European nations, whereby data is stored alongside some of Europe’s most powerful supercomputers. European researchers can preserve, find, access, and process data in a trusted environment, as part of the EUDAT Collaborative Data Infrastructure. One of EUDAT’s main ambitions is to bridge the gap between research infrastructures and e- Infrastructures through an active engagement strategy. It is supported by EU DG RTD and EU DG CONNECT.

EUDAT contributes to the integration of the EUDAT B2Services into the Blue-Cloud VRE and is mainly responsible for making the Blue-Cloud data and service catalogues interoperable and accessible via the EOSC portal. EUDAT is one of the horizontal e-infrastructures (EUDAT, DIAS, D4Science) that are aimed to capitalise on what already exists and to develop and deploy the Blue Cloud framework.

Type & number of data sets

In principle there is no limit to the number of files that can be added to each service (although there is a finite amount of storage currently associated with each service). In terms of file sizes, there are limitations for some services as described below. Data form different fields can be added to each service (see some use-cases of EUDAT services)
  • B2DROP: 2GB per file, with a maximum of 20GB per user.
  • B2SHARE: Currently the maximum file size is 10 GB and the maximum size for a record is 20GB. The current limits are given here.
  • B2SAFE: unlimited, but very large file transfers are subject to network stability of course.

Core Services

EUDAT has developed a service stack that forms the Collaborative Data Infrastructure (CDI). The services are as follows:

  • B2SAFE, Replicate Research Data Safely.
  • B2STAGE, Get Data to Computation.
  • B2FIND, Find Research Data.
  • B2SHARE, Store, Share and Publish Research Data.
  • B2DROP, Sync and Exchange Research Data.

In addition, a set of EUDAT core operational services, essential for the management of the CDI have been defined as follows:

  • B2ACCESS (identity and authorisation), easy-to-use and secure Authentication and Authorisation platform.
  • B2HANDLE (Persistent IDentification (PID) management), a service to register persistent identifiers called Handles to data objects and retrieve data objects via these identifiers, serving a purpose similar to DOIs for papers.
  • B2HOST, a Service Hosting Framework that allows communities to deploy and operate their own applications and data-oriented services on machines next to the data storage.
