San Mateo County Open Data: Dataset Metadata and Licence

smcgovopendata/dataset-metadata

Returns the metadata of one dataset on the San Mateo County open data portal by its dataset id: name, description, category, attribution, licence, and when the data and metadata were last updated. Use it to check a dataset's licence and freshness before querying its rows. An unknown dataset id returns a validation error. Passed through unmodified and served by Eden Engine; not an official County of San Mateo product.
