B2SHARE

Introduction

B2SHARE is a service developed within EUDAT and EUDAT2020 project. It provides researchers a solution for storing and sharing small-scale research data from diverse contexts. The local instance at Forschungszentrum Jülich is an offer for everyone within the research centre to share or publish their results with a URL and a PID.

B2SHARE can handle research data in a single file and distributed data across multiple files. The research data and additional metadata are stored in one record. While creating a record the user is able to fill in the (community specific) metadata. Each submitted record and each file within the record is provided with a PID (persistent identifier). A PID is a digital reference to a digital object (i.e. the record) which allow users to find the object with a web browser. The PID can be used in publications to refer to the research data.

Usage

Authentication

If you want to use B2SHARE you have to login. During the login process B2SHARE will forward you to B2ACCESS, the central EUDAT identity management service, which provides the user management for B2SHARE. You can easily login with your email address and password from research centre Jülich if you select Forschungszentrum Jülich GmbH in the list on right site.

Upload data

If you want to create a new record, you have to select “Create a new record”. Thereafter you fill in the name of the record and choose a community for specific metadata. “Create Draft record” will create a new record with given name and metadata schema. You are forwarded to your draft. Here you are able to upload the research data and fill in the metadata. To publish the draft you must select “Submit draft for publication” and “Save and Publish”.

B2SHARE offers a rest API to create drafts, upload files, fill in metadata and publish the record, too. If you want to use this API, you must create an API token within the profile section in B2SHARE.

External resources

B2SHARE is listed in several meta repositories for scientific data:

Nature Publications accept B2SHARE as an institutional repository for scientific data accompanying publications by FZJ staff members. The publisher’s namespace for the repository is "FZ-Juelich B2SHARE".

Limitations

The service has two limitations:

  • The maximum file size is 50 GB and the maximum record size is 200GB.
  • The number of files within a record is unlimited.

Retention policy

JSC will keep the data records and make them available for at least 10 years after upload. In the unlikely event that B2SHARE will have to close operations, JSC will migrate all records to other suitable repositories and make sure that the records remain accessible through their ePIC PIDs and DOIs.

Testbed

Because the PIDs should only attached to useful publications and not to test files we offer a testbed, too. It has only limited disk space, so uploads will be removed regularly and no PID will be assigned to the uploads.

Support

Should you need support with any of the offerings or have questions, please contact the data services support team at ds-support@fz-juelich.de.
