Currently the repository provides the data files for download in original CSV, XLS, ODS, XML or JSON versions.

The repository is constantly updated with improvements, and one of the roadmap items is the organization into ready-made data models, with SQL dump to easily be incorporated into MySQL, PostgresSQL, SQLite, MongoDB, etc.

Organizations with available data: IBGE, INEP, Brazilian Government.
