Public Data refers to datasets that are openly available to the public, without any restrictions on access or usage. Such data can be utilized by anyone for various purposes, including research, policy-making, innovation, and transparency. Public data is often released by government entities, public institutions, and organizations committed to open data principles.
Historical Context
