Metadata Catalogue

An online, searchable catalogue detailing information about all the data sets available within the LongITools consortium and the institutions and common data model involved.

The LifeCycle data catalogue has been used as the basis to develop the catalogue, with the addition of further data sets and variables. To make the data interoperable, the data sets are being mapped to standard variables agreed upon within the LongITools consortium ready for analysis and harmonised into common formats.

The catalogue will enable exposome researchers to assess all the data sets available from LongITools, and the suitability of the data sets to answer specific research questions.

The catalogue software is free and open source, available for other projects to reuse, as part of the MOLGENIS** software platform.

The actual data within the data sets will be accessible to researchers via DataSHIELD* which ensures security and legal compliance when using the data, following the necessary data access procedures.

By bringing together all existing networks and cohorts, in one open science platform, we will ensure better data reuse and increased benefit to scientific communities.

Timescale for completion: Spring 2022

Deliverable submitted to European Commission

A public report outlining the Metadata Catalogue and the progress made was submitted to the European Commission on 26th April 2022. The report is awaiting approval.

Progress update – March 2022

Harmonisation of the variables is now complete. A user focus group meeting was held during March 2022 to gather feedback and suggestions for improvements to the functionality and aesthetics of the Metadata Catalogue. This feedback is now being worked through to make refinements ahead of the public launch of the Catalogue.
