Opening data in any public agency is a process that should be planned carefully and with the involvement of various actors: keepers of the databases, Information Technology (IT) professionals, public managers, and technicians in the areas of interest. As a rule, all databases that the agency already owns can be published. However, we must ensure that the databases selected for publication do not fit into the exception scenarios provided for in the Brazilian Information Act. If these databases contain any confidential information, that data must be hidden before it is published.
This section of the guide suggests creating an "Open Data Plan." This is a strategy for starting the opening data processes or assessing the open data situation at a given agency. However, each government institution is free to decide how to open their databases in accordance with state and federal legislation on access to information.
