EUDAT-B2FIND is the cross-disciplinary discovery service of EUDAT that allows facetted search over distributed research data repositories. It indexes metadata from different research domains and memory areas within EOSC-hub and beyond. B2FIND follows a flexible approach for data providers, supporting various metadata schemas, harvesting methods, and formats through its ingestion workflow.

EUDAT-B2FIND is is the cross-disciplinary discovery service of EUDAT
B2FIND is research community driven and allows a cross-discipline facetted search over
a wide scope of distributed and various research data repositories
The implementation of the discovery portal is based on CKAN and SOLR
- Users can search for research data via a GUI with powerful facetted search features or a CLI
(python script) using the RESTful CKAN-API
- Allows the access to the underlying data resources by providing persistent identifiers
- Joining B2FIND as a data provider and publishing metadata follows a low barrier approach and
is implemented by a modularized ingestion workflow
In the ‘Guidelines for Dataproviders’ detailed support and detailed usage policies and
terms of use are provided
B2FIND is accessible to everyone and is open to any kind of research data.
Use cases :
- End users search for cross-domain research data in order to reuse them for their own research
- Communities publish and index metadata to make their research data visible and searchable
across a wide range of disciplines

B2FIND was build up for
Providing an easy-to-use webportal that enables
researchers and scientists from all over the world to
easily search, find and access research data
Enabling Scientific Communities to make their research
data searchable and findable
Following a flexible and low barrier approach for data
providers by supporting
- several domain specific metadata schemas and standards
- different harvesting methods
- divergent metadata transfer formats

Motivation

5. 5
B2FIND
is the cross-disciplinary discovery service of EUDAT
will be the central indexer for EOSC-hub
offers a comprehensive metadata catalog that includes
metadata records for research data from
- very different research domains
- distributed over memory areas within EOSC-hub and beyond
also acts as a data curator = endorsing data providers in
- the creation
- dissemination and
- quality assurance
of their metadata

The implementation of the discovery portal is based on
CKAN and SOLR
- Users can search for research data via a GUI with powerful
facetted search features or a CLI (python script) using the
RESTful CKAN-API
- Allows the access to the underlying data resources by providing
persistent identifiers
A modular workflow was set up for the metadata ingestion
- Joining B2FIND as a data provider and publishing metadata
follows a low barrier approach
- Community outreach and negotiation with the data providers
about the specific mapping and needs is central
- The modular ingestion workflow is implemented based on a
comprehensive Python source code stack
