NADA, the open source microdata cataloguing platform from IHSN and the World Bank, where statistics offices and research institutions publish survey and census catalogues with DDI metadata, controlled access and a public search portal.
Overview
NADA is the microdata cataloguing system that national statistics offices, central banks and research institutions run to publish their survey, census and administrative data holdings as a searchable online catalogue. Developed by the International Household Survey Network and the World Bank, it is the software behind many national and institutional microdata libraries. Curators document each study with DDI CodeBook and Dublin Core metadata, covering not just the dataset but its questionnaires, sampling, variables and related reports, so a study remains interpretable and citable long after collection. Researchers browse and search the catalogue by keyword, country, year or collection, compare studies, and request the data itself under the access policy the curator assigns: direct download, licensed access with an application workflow, or enclave only listing. Version 5.6 adds a Vue based admin interface, per user and per collection permissions, indicator and time series support with charts and a data API, resumable uploads for large files, and built in usage analytics. Everything a curator does in the browser is also available through a REST API, with official PyNADA and NADAR clients for scripted publishing.
Why the cloudimg image
cloudimg turns a multi step LAMP install into an appliance that answers as soon as first boot finishes: the database is provisioned, the upstream migrations are applied and the first administrator already exists, so there is no web installer wizard to click through and none ever reachable, because the catalogue marks itself installed before the web server is allowed to answer. Institutional data custodians care about credentials, and this image treats them accordingly: every instance generates its own MySQL root password, application database password, site administrator password and a personal admin API key at first boot, stores them in a root only file, and rotates the application encryption key that upstream ships as a fixed default, so no two deployments share any secret and no known login exists. The build proves the catalogue actually works end to end, signing in through the real login flow and publishing, finding and removing a study through the API, not merely that a page loads. The database listens only on loopback, the base is fully patched, and every deployment is paired with a step by step deploy guide, backed by 24/7 cloudimg support.
Common uses
- Publish a national or institutional microdata catalogue with DDI metadata
- Manage licensed access requests and controlled downloads for sensitive datasets
- Automate study publishing through the REST API with PyNADA or NADAR
