How do I find data on

You can search from its catalog of government data from across the Federal Government. Once in the catalog, to find datasets you can:

  • Enter keywords in the search box.
  • Browse on the left side through types, tags, formats, groups, organization types, organizations, and categories.  Clicking on multiple items narrows your search.  You can click on the “x” to the side of any single item to remove it from the search, or “clear all” to remove all selected items in a category.
  • Search by geospatial area by drawing a boundary box on the map at the left side and clicking “Apply” to find all datasets that are tagged for that geographic area.
  • Interactive Datasets” at the top right takes you to datasets that can be explored online through a web browser.

Once you find a dataset or tool of interest, click on the title and you will be taken to a page with more details on that specific dataset or tool. Some datasets are downloadable, while others are links to web sites or apps that help you access or use the data.

Please note that by accessing datasets or tools offered on, you agree to the Data Policy, which you should read before accessing any data. If there are additional datasets that you would like to see included on this site, please suggest more datasets here.

How are the datasets in collected?

Under the terms of the Federal Open Data Policy, newly-generated government data is required to be made available in open, machine-readable formats, while continuing to ensure privacy and security.

Government data publishers looking to get their data on should read the detailed guide: How to get your open data on The team typically works with a designated open data point of contact as a liaison for each agency. Data publishers should consult with their agency point of contact to include any additional datasets on If you need help determining who your open data point of contact is, please contact us.

Federal CFO-Act agencies are required to:

  • Create a Single Agency Data Inventory. Agencies are required to catalog their data assets, just like they would inventory computers or desk chairs, to better manage and use these resources.
  • Publish a Public Data Listing. Agencies are required to publish a list of their data assets that are public, or could be made public. This list is made available as a data.json file hosted at the primary domain of the agency (eg.
  • Develop New Public Feedback Mechanisms. Agencies are required to set up feedback mechanisms to engage the public about where agencies should focus open data efforts, such as facilitating and prioritizing the release of datasets. Agencies are also required to identify public points of contacts for agency datasets.

Agency Public Data Listings are made available on agency websites as JSON files following the Project Open Data metadata schema (at and are then harvested into the central catalog for  Each agency is responsible for its own data.

How can I add my government data to is primarily a federal open government data site. However, state, local, and tribal governments can also syndicate metadata describing their open data resources on for greater discoverability. does not host data directly, but rather aggregates metadata about open data resources in one centralized location. Once an open data source meets the necessary format and metadata requirements, the team can pull directly from it as a Harvest Source, synchronizing that source’s metadata on as often as every 24 hours.

Step 1: Organize your open data for the Pipeline

Getting your data source ready for harvesting by the catalog differs depending on the type of source:

  1. Federal Data with Project Open DataThe most common source is the Public Data Listing as required by the Federal Open Data Policy.
  2. Federal Geospatial DataA number of federal agencies hold geospatial data which has separate requirements under different legal authorities.
  3. Non-Federal Data: Non-federal sources are not covered by the Federal Open Data Policy, but can be included in the catalog voluntarily. Depending on your platform, creating this harvester might just be the push of a button or it could take a little more work, but the team will walk you through it either way.

Step 2: Coordinate with

  1. Contact the team. Contact the team ( to let them know you’d like to get started. Please include a link to your metadata in the data.json format or let us know if you have questions about how to create a data.json file from your current database along with any relevant links.
  2. Connecting the pipes.The team will create a new Harvest Source that will automatically collect information about your datasets and update whenever changes are made on your data catalog.
  3. Testing. The team will test to ensure the harvester works properly. If anything seems wrong, the team will help you configure your data catalog so that can collect your datasets without any errors.
  4. Live within 24 hours! Once the harvester has been tested successfully, will start automatically consuming information about your datasets and all the basic details of your datasets will be available on with links to the source and your open data policy.

What technology is built with?

This catalog is built on an open source data management system called CKAN. CKAN is used by governments around the world including Australia, Austria, Brazil, Germany, Norway, and the UK. Started as a project by the Open Knowledge Foundation in 2007, all development is on Github and contributors are welcome.The Open Knowledge Foundation is a non-profit organization focused on opening up all knowledge (data and content) to see it used and useful. Founded in 2004 and with chapters around the world, it has been pioneering open source tools and open data from the start.

What standards were used to develop the metadata displayed on follows the Project Open Data schema – a set of required fields (Title, Description, Tags, Last Update, Publisher, Contact Name, etc.) for every data set displayed on

What if I am having difficulty downloading a dataset from the catalog?

Some web browser configurations, particularly those that are designed for high-security computing environments, can interfere with access to certain datasets from the catalog. This is most commonly related to government websites that use security certificates and end user browsers that are not configured to recognize those certificates as being authoritative. If you are having difficulty downloading one or more datasets from the catalog, please contact your local IT support staff to determine whether browser configuration issues can be addressed for your workstation.

What metrics are available about data on collects information on the total number of datasets and dataset collections. Fluctuations in dataset and dataset collection totals may occur as the result of resolving issues with dataset duplicates or merging datasets into dataset collections. also tracks Federal Agency Participation and visitor metrics.
