According to the International Open Data Charter(1), it defines open data as those digital data that are made available with the technical and legal characteristics necessary so that they can be freely used, reused and redistributed by anyone, at any time and anywhere.

But what are the bases that are governed to comply with the definition of open data, the International Open Data Charter gives us the principles:

- Open by default:

There must be free access to government data.

Governments must adopt strategies for the creation, use, exchange, and harmonization of open data.

Open data must not violate the right to privacy.

- Timely and comprehensive:

The prioritization of what data to open should be done in consultation with current and potential users.

The data must be comprehensive, accurate, and high quality.

- Accessible and usable:

Open data helps improve decision making.

There should be no bureaucratic and/or administrative barriers to accessing the data.
