Open NY: Dataset Metadata and Licence

nyopendata/dataset-metadata

Descriptive metadata for one dataset on the Open NY (data.ny.gov), chosen by its 8-character dataset id: name, description, publishing agency (attribution), declared licence, category, tags, creation and last data update times, the data and web addresses and the publisher's custom fields such as update frequency. Use it to check what a dataset holds and under which licence before querying its rows. An unknown dataset id is refused as a validation error. State of New York data as served by Omnial; not an official State of New York product.
