Atlas of Longitudinal Datasets

The Atlas of Longitudinal Datasets is a Wellcome-funded portal for discovering global longitudinal research datasets, bringing together comprehensive metadata on studies from around the world.

Data Entry Platform

Behind the public site is a powerful data entry platform where the Atlas team can find, validate, and curate metadata about longitudinal studies worldwide. The platform streamlines the process of maintaining accurate, up-to-date information across thousands of datasets.

Automated Monitoring

Web spiders continuously monitor study websites to validate existing data and detect updates, alerting the team to changes that may require attention. This automated approach ensures the Atlas remains current with minimal manual effort.

Public Discovery Interface

The public-facing portal provides lightning-fast search and filtering through a combination of client-side and API search strategies, delivering instant results as users explore the dataset catalogue. Strong SEO ensures each dataset is easily discoverable through search engines, maximising the reach and impact of the resource.

Delosis Contribution

Delosis designed and built the complete platform end-to-end: the internal data management system, automated web spiders, and the highly optimised public discovery interface.
