# Meta Data All the data driven components in CGView have the ability to contain meta data. Meta data (i.e. user-defined key:value pairs) can be stored simply as an object property named meta on most objects. TODO: * examples * adding through constructor * adding though add actions (e.g. addFeatures(data, meta)) * meta can be in data for per obejct data * can also be added as second argument to be added all features (NOT IMPLEMENTED YET) * meta data is never used by CGView * good place to store extra data for external projects (e.g. proksee) * example would be extra qualifier tag data for features * only if meta data exists for an object, will it be exported in json * meta data will also be imported from json * HOW will meta data merge options.meta and constructor meta argument. Is the meta argument needed? * to_json: default will be to export all meta data. Have option to ignore meta data.
