Opening databases in the terms suggested by this guide involves providing complete information on the Web in non-proprietary formats with unrestricted, free access for anyone, such that anyone can reuse the data for any purpose without restrictions. This paragraph is a brief summary of what can be considered an "open license", and the conditions under which the custodian of the data grants the consumer permission to use it. Without this license, the data cannot be considered "open," because there is no guarantee that its use is kept under open data principles.
An "open license" is also important in respecting the Brazilian Information Act. The National Infrastructure of Open Data, of the federal government has not yet reached a conclusion as to whether the Brazilian legal system is sufficient to deal with open government data without the need for licenses, if other existing licenses fit into the Brazilian context, or if it will be necessary to create a specific license for Brazil. For example, in the Copyright Act, Brazilian legislation explicitly provides for the protection of databases that constitute "intellectual creation." On the other hand, the Brazilian Information Act states that the state must provide access to all information that it creates or holds, provided that data is not considered confidential. The interaction of these laws is still an object of study.
