{"@type": "dcat:Dataset", "accessLevel": "public", "contactPoint": {"@type": "vcard:Contact", "fn": "Jonathan Levy", "hasEmail": "mailto:no-reply@data.cityofchicago.org"}, "description": "<b>NOT CURRENT DATA</b> - This dataset contains <b>past</b> records from the <a href=\"https://data.cityofchicago.org/d/97wa-y6ff\">Public Chauffeurs dataset</a>. It is intended for historical reference, not current licensing information. It follows the format of the Public Chauffeurs dataset, with the addition of two additional columns at the end.\n\nThe Last Valid Date column indicates the most recent timestamp when that set of values appeared in the Public Chauffeurs dataset.  It indicates when that version of the license record <b>stopped</b> being valid (was replaced by an updated version), not when it <b>started</b> being valid (replaced a previous version or was created for a newly added license). Due to various technical limitations, the Last Valid Date may be artificially late and intervening versions not shown are possible.\n\nThe Record Version ID is a unique identifier that has no meaning beyond distinguishing different versions of the same license.\n\nPlease read the article linked below for more information.\n\nDue to a change in source systems, many licenses will appear to have changed on 11/21/2018, even if no actual change to the license took place. Some records between 11/19/2018 and 11/21/2018 may be unreliable and should be used with caution. The Expires column was added with the move to the new source system so will not appear in earlier records.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://data.cityofchicago.org/api/views/q9nk-vsym/rows.csv?accessType=DOWNLOAD", "mediaType": "text/csv"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofchicago.org/api/views/q9nk-vsym/columns.rdf", "describedByType": "application/rdf+xml", "downloadURL": "https://data.cityofchicago.org/api/views/q9nk-vsym/rows.rdf?accessType=DOWNLOAD", "mediaType": "application/rdf+xml"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofchicago.org/api/views/q9nk-vsym/columns.json", "describedByType": "application/json", "downloadURL": "https://data.cityofchicago.org/api/views/q9nk-vsym/rows.json?accessType=DOWNLOAD", "mediaType": "application/json"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofchicago.org/api/views/q9nk-vsym/columns.xml", "describedByType": "application/xml", "downloadURL": "https://data.cityofchicago.org/api/views/q9nk-vsym/rows.xml?accessType=DOWNLOAD", "mediaType": "application/xml"}], "identifier": "https://data.cityofchicago.org/api/views/q9nk-vsym", "issued": "2018-11-21", "keyword": ["transportation", "link to article present", "licenses", "historical"], "landingPage": "https://data.cityofchicago.org/d/q9nk-vsym", "modified": "2026-04-12", "publisher": {"@type": "org:Organization", "name": "data.cityofchicago.org"}, "theme": ["Community & Economic Development"], "title": "Public Chauffeurs - Historical"}
