ALFRED data dump Information

A Document Type Definition (DTD) has been developed for importing and exporting ALFRED data in XML format. Researchers can download data useful for analysis into a single compressed “data dump” file in the declared XML format. The data dump can include either all relevant information (including descriptions) or only the data relevant to statistical analyses. The data structure with description and the relationship between the tables in ALFRED is also available.

The XML files provided here include, a zipped file with xml file of the entire database and the DTD files required for the validation of the xml file, and separate XML files for each table. The xml files will be updated twice a month.
