New Jersey Open Data Dataset Metadata: Publisher, Description, Last Updated

njopendata/dataset-metadata

Descriptive record of one New Jersey Open Data Center dataset, looked up by its portal id (eight characters in two groups of four, such as gbrz-b7qh): name, description, publishing agency, category, tags, created and last-updated times, posting frequency, contact and the dataset's own licence field (null when the publisher states none). Use it to check provenance and freshness before relying on a dataset. Metadata only; no dataset rows are returned. New Jersey Open Data Center data, passed through unmodified and served by Eden Engine; not an official State of New Jersey product.
