Metadata Project
The CTN has led some of the largest HIV cohort studies in Canada, but optimal use of the data is limited by lack of a central repository and standardized data collection. To solve this, CTN researchers and staff developed the Metadata Project, categorizing collected variables into 3 tiers and 35 domains to improve reusability of existing data, highlight research gaps, and enhance data practices.
