B2ACCESS is an easy-to-use and secure Authentication and Authorization platform developed by EUDAT. B2ACCESS is versatile and can be integrated with any service. When B2ACCESS is integrated with a given service, the user may log in by using different methods of authentication:
EUDAT IDs are created by the B2ACCESS upon registration. Therefore B2ACCESS is an Identity Providers for the users that do not have neither a Google account nor a Home Organization Identity Provider. In these cases, B2ACCESS offers also the tool for the managements of the EUDAT IDs.
B2ACCESS can be found here: https://b2access.eudat.eu
B2ACCESS is based on Unity IDM. The following picture shows the different methods of authentication and the flow within the B2ACCESS system.

In order to access a data object stored in EUDAT, an associated PID is needed. B2HANDLE enables EUDAT services and user communities to assign PIDs to different kinds of managed objects stored in the EUDAT CDI.
PIDs are used in EUDAT to reliably identify and cite data objects over a long period of time and it is thus a vital part of long-term data management. Moreover, data can be directly retrieved by PIDs and corresponding key-metadata can be stored together with them in the so-called PID entry.
The B2HANDLE service encompasses management of identifier namespaces (Handle prefixes), establishment of policies and business workflows, operation of Handle servers and technical services, and a user-friendly Python library for general interaction with Handle servers and EUDAT-specific extensions.
The underlying technology of B2HANDLE is based on the Handle System, which is a reliable, redundant and scalable system built on top of an open architecture. B2HANDLE is mostly transparent to the end-users, especially shielding them from the complexity of infrastructure details.
B2HANDLE is a distributed service, with the organisations hosting the service mirroring each other's Persistent Identifiers. This ensures the sustainability and reliability of PIDs in the EUDAT domain.
In the EUDAT ecosystem, EUDAT services make use of B2HANDLE to guarantee data access, long lasting references to data and to facilitate data publishing. B2SAFE and B2SHARE use the service to create and manage PIDs for their hosted data objects, whereas B2FIND and B2STAGE use the resolving mechanism of B2HANDLE to retrieve and refer to objects.
B2DROP is a secure and trusted data exchange service for researchers and scientists to keep their research data synchronized and up-to-date and to exchange with other researchers.
An ideal solution to:
The service is simple to use and open to all researchers, scientists, communities alike to synchronise and exchange data with one or multiple users. B2DROP will be fully integrated with the B2 suite of services to allow user-friendly data sharing.
The BETA version is on-line and you are invited to register as a user in a few simple steps and start using the EUDAT sync and share solution for data at https://b2drop.eudat.eu
B2SHARE is a user-friendly, reliable and trustworthy way for researchers, scientific communities and citizen scientists to store and share small-scale research data from diverse contexts.
A winning solution to:
Who benefits from it?
B2SHARE is optimized for researchers who:
The success of this service is based on mutual trust, in that the depositors must be able to rely on the professional management of their data by the service provider, and the service provider rely on the users depositing data with appropriate content.
B2SHARE is open to all researchers and scientists who are affiliated to research institutions, universities as well as to individual researchers (citizen scientists). Researchers who want to deposit research data must register, a requirement for the upload service.
The user documentation and the FAQ describe how to use the B2SHARE service. Educational material (such as screencasts) and a service helpdesk are avaliable. Community managers who want to get more details about this service, please contact support-request.
The B2SHARE service is free of charge for European scientists and researchers. The service is professionally managed and data is safely preserved via a backup or replication service, and a disaster recovery plan is available.
The B2SHARE service will be advanced on top of the existing features:
B2SAFE is a robust, safe and highly available service which allows community and departmental repositories to implement data management policies on their research data across multiple administrative domains in a trustworthy manner.
A solution to:
Tomorrow’s corpus of research data will be a domain of registered data objects and collections where persistent identifiers (PIDs) identify the data objects and collections, while information associated with the PIDs allows the integrity and authenticity of the data to be checked. Furthermore, data management operations will be governed by formalized policy rules that will also form the basis of any audits to assess quality. To meet this vision, EUDAT’s B2SAFE service is based on the execution of auditable policy rules and the use of PIDs, as offered by the EPIC Handle service.
This will increase trust in data and services in the anonymous world of data re-usage and re-purposing. Suitable technology that allows to execute sequences of policy rules will be applied, and the EUDAT data federation will be built on trust agreements, which ensure that ownership rights to the data reside with the originators. To make replicas accessible via community-defined portals, service providers will need to host community-based software respecting all access permissions. Although the EUDAT project is initially funded for three years, we will ensure persistent access and services through mutually beneficial partnerships with data centres that have long term funding.
Any community and departmental data repositories that have a proper repository infrastructure supporting PIDs and metadata describing the properties and context of the data being replicated can participate in the B2SAFE service. The replication service currently relies on iRODS but also supports other federation technologies. Participating repositories can choose to use iRODS and link it with their local repository to enable a tight integration to the EUDAT infrastructure, or use other easy-to-integrate federation approaches and client libraries.
EUDAT will help interested community centres to set up and use this service by running training courses, and providing support for the necessary adaptation work, including offering a service helpdesk. To find out more details about the EUDAT B2SAFE service, please contact the EUDAT service team at the address below.
EUDAT is happy to talk to any interested communities about their detailed requirements with respect to the B2SAFE service.

B2STAGE is a reliable, efficient, light-weight and easy-to-use service to transfer research data sets between EUDAT storage resources and high-performance computing (HPC) workspaces.
The service allows users to:
B2STAGE is aimed at researchers or communities, who need:
The service aims at facilitating flexible data staging by offering different configuration options to support as many scenarios as possible. It combines a server component and various client interfaces.
The staging functionality is an extension of the iRODS system with a GridFTP interface using a component being developed for this purpose - the GridFTP Data Storage Interface for iRODS (https://github.com/EUDAT-B2STAGE/B2STAGE-GridFTP). Therefore, the transfer of data is performed through a reliable, high-performance protocol - the GridFTP. On the client side, users have a rich selection of alternatives. In principle, any existing client supporting the GridFTP protocol can be used – globus-url-copy, GlobusOnLine, UberFTP, and the XSEDE-EUDAT File Manager which also supports a wider range of transfer protocols (i.e. GridFTP, FTP, native iRODS, etc.). All proposed solutions offer the same core functionalities and can be used seamlessly. EUDAT also provides a script to facilitate the integration of B2STAGE within existing community solutions, such as web portal, workflow engine, etc. The script, named Data Staging Script (DSS), as well as providing common data staging functionalities, also allows the retrieval of PIDs assigned to ingested data.
How can you use B2STAGE?
EUDAT offers B2STAGE to all registered researchers and interested communities enabling them to make use of the service for stage data out of EUDAT, and ingest any computational result back. Access to remote HPC facilities should be negotiated and arranged by individual users in parallel. To help researchers to use the B2STAGE service, EUDAT offers documentation, educational material (such as screencasts) and a service helpdesk. To find out more details about this service, please contact the EUDAT B2STAGE team at the address below.

B2FIND is a discovery service based on metadata steadily harvested from research data collections from EUDAT data centres and other repositories. The service offers faceted browsing and it allows in particular to discover data that is stored through the B2SAFE and B2SHARE services. The B2FIND service includes metadata that is harvested from many different community repositories.
B2FIND allows users to:
This service is primarily aimed at the many researchers who want to:
Metadata is harvested from metadata providers using standard technologies. The community itself decides which metadata is made available for EUDAT. A sophisticated framework ensures that metadata providers are harvested regularly to always display complete and up to date information. EUDAT provides an optimized translation from community metadata schema to standard facets in the B2FIND metadata catalogue.
B2FIND is open to all researchers and scientists free of charge. Research communities who want to provide their metadata to B2FIND should contact us through http://www.eudat.eu/support-request
EUDAT is also interested in helping emerging communities to set up their own metadata infrastructure and help them publish their metadata.
