    "description": "The descriptor is the central file in a Data Package. It provides: 1) General metadata such as the package's title, license, publisher etc.; 2) A list of the data 'resources' that make up the package including their location on disk or online and other relevant information (including, possibly, schema information about these data resources in a structured form).   A Data Package descriptor MUST be a valid JSON object. (JSON is defined in IETF RFC 4627). When available as a file it MUST be named datapackage.json and it MUST be placed in the top-level directory (relative to any other resources provided as part of the data package). The descriptor MUST contain a resources property describing the data resources. The descriptor MAY contain any number of other metadata properties. Adherence to the data package descriptor specification does not imply that additional, non-specified properties cannot be used: a descriptor MAY include any number of properties in additional to those described as required and optional properties.",
