<!--StartFragment-->Challenges in the Maintenance of FAIR-compliant Paediatric Data-Sharing Repositories<!--EndFragment-->

To meet the growing need for strong clinical evidence on a global scale, both publicand private sectors have invested to standardise health data elements and achievegreater connectivity and interoperability of health data systems. This is enabled byFAIRification (making Findable, Accessible, Interoperable, and Reusable) of clinicaltrial data increasingly recognised as a crucial step in enhancing the value and utility ofclinical data across the research community. This is even more relevant in thepaediatric and rare disease field where data remains highly fragmented in terms ofdata collection practices, ontologies, and clinical reporting standards, and often lockedin silos with diverse formats and standards.
