Adapted ODISSEI Portal prototype – More data to find and improved interface

13 February 2023

During the National Open Science Festival in September 2022, the first prototype of the ODISSEI Portal was launched. The Portal combines metadata from a wide variety of research data repositories into a single interface, allowing for advanced queries to support findability, and facilitate data access to social science datasets in the Netherlands. Portal had an upgrade. 

The prototype has been upgraded so that it is now possible to find metadata of social science datasets from DataverseNL’s partners. This means users can now access more than 1,000 studies from 13 universities and other research institutes affiliated with DataverseNL. Combined with metadata from CBS, Centerdata and DANS, the Portal provides access to information from more than 5,000 datasets.

Improved ingestion pipeline and data citation 

In this second version of the ODISSEI Portal prototype, metadata ingestion has been improved, making it even easier to add new metadata providers to the Portal in the future. In addition, the data citation has been corrected and now includes a reference to the publication year of the dataset.

Transparency and provenance

To allow users to understand the processes that have been used to get the metadata into the Portal, a provenance field has been added. Users can find a list of all the steps that were taken, the scripts that were used and their corresponding Github repositories. 

Further developments

The Portal will be further developed and improved over the next two years by ODISSEI, DANS, VU and SURF as part of the ODISSEI roadmap project.

The collected metadata will be enriched with existing controlled vocabularies to increase the findability of the information. More metadata providers will be added to the Portal with the ultimate goal of giving researchers access to information about all relevant social science datasets in the Netherlands. Data providers from the ODISSEI community are encouraged to get in touch with the Portal team to make their metadata available in the Portal.

Last but not least, we are working on functionalities around the data access broker, which should enable users to request data directly from the ODISSEI Portal from the various data providers.
