Open Data DC Dataset by Catalogue Id: Licence, Source, Description (Washington DC)

dcopendata/dataset-by-id

One Open Data DC (Government of the District of Columbia) catalogue record by its 32-character id: title, summary, long description, licence, source agency, type, tags, last-modified time and service link. Only datasets licensed CC BY 4.0 or CC0 1.0 are returned: an unknown id, or a dataset with a blank or custom licence, returns an empty feature list, not an error. Get ids from the dataset search tool. A catalogue record, not a dataset's rows; description and licenseInfo are publisher HTML, so escape them before rendering. Credit the record's named source. Data retrieved from the Open Data DC catalog, passed through unmodified and served by Eden Engine; not an official Government of the District of Columbia product.
