Microdata Cataloging Tool (NADA)
NADA is a web-based cataloging system that serves as a portal for researchers to browse, search, compare, apply for access, and download relevant census or survey information. It was originally developed to support the establishment of national survey data archives. The application is used by a diverse and growing number of national, regional, and international organizations. NADA, as with other IHSN tools, uses the Data Documentation Initiative (DDI), XML-based international metadata standard.
System Requirements
NADA requires a server running PHP 5.3 or later with a MySQL database.

| Description | NADA 4.4 is the latest official release and requires at least PHP 5.3 or above to run. We strongly recommend that you use PHP 5.5 or later with the MySQL 5.x database.
The current release fixes issues related to PHP 5.6 and file uploads for resources. In newer versions of Chrome and other browsers, Flash is disabled by default which causes the file upload features on the NADA site adminstration pages to fail. This release fix replaces Flash with HTML5. For NADA 4.3 users, please follow the steps below to apply the patch.
1. Make a backup of your NADA website. If complete backup is not possible, please backup the “Application” and “System” folders 2. Download the patch zip file: NADA43-patch 3. Unzip the patch files into the NADA root folder to replace existing files |
