The data on Cities.Data.gov is brought together from many official government sites. The policies for the release of those data vary from one city to another. Below you can find the detailed policies and developer resources for each catalog in this collection.
Want to add your city to Cities.Data.gov?
To federate your data into Data.gov, follow the procedures below. In general, federation will require some additional coordination between the Data.gov team and representatives of the local government open data site. The data remains on the local government platform, but the catalog information is federated to the Data.gov catalog to allow people to discover government data from all across the nation.
Step 1. A city official needs to send a note to the Data.gov team <mail to: Jeanne.Holm@jpl.nasa.gov> stating the URL of the official open data site, the data policy (see samples above), and a request to have the city data federated to Data.gov.
Step 2. Depending on the open data platform being used…
If the local data site is using the Socrata Open Data Platform:
Step 1 - Log in to your Socrata administration console
Step 2 - Click on “Federation”
Step 3 -
- For Cities: search for “cities-datagov.demo.socrata.com”
- For Counties: search for “counties-datagov.demo.socrata.com”
- For States: search for “states-datagov.demo.socrata.com”
Step 4 - Click “Publish”
- This sends a request to the Data.gov Administrator
Step 5 - Data.gov approves request
If the local data site is using CKAN or Junar:
Step 1 – In the note to the Data.gov team, include the catalog URL and indicate whether site is on CKAN or Junar
Step 2 – The Data.gov team provide the federation
If the local data site has another open data solution
Step 1 - In the note to the Data.gov team, include the URL for the publishing catalog information (e.g. http://YourDomain”/catalog.xml) and indicate whether catalog information is published in a DCAT-compliant format.
Step 2 – The Data.gov team will work with you to help provide a DCAT-compliant format and a connector script for importing the catalog information.
Step 3. Receive a notification that you are now part of the National Open Data Platform!
