Metadata is "data that provides information about other data". In other words, it is "data about data". It is not the same as the format of the data, and the term overlaps - but should not be confused with - database schema. The Open Data Handbook says that "It is essential to publish data with adequate metadata to aid both discoverability and usability of the data." There are many kinds and formats of metadata, depending on the kind of gap they are helping to address. Portals like opendata.swiss collect metadata from diverse sources and make it easy to explore.
