NEW
A dataset available for public use under an open license that permits access, reuse, and redistribution, typically with clear metadata and documentation.
DESCRIPTION
Open datasets are shared for public benefit under licenses allowing broad reuse and redistribution. They are often published on portals with APIs, metadata, and machine-readable formats. Clear licensing (e.g., Creative Commons) and standards like DCAT improve discoverability and interoperability. Open data supports transparency, research, civic innovation, and commercial reuse. Publishers should document provenance and ensure privacy and ethics when releasing data. Quality and timeliness remain essential for usefulness.
