Multi-City Data Sharing

Facilitating greater access to technology for all New Yorkers is a primary agency goal. In accordance with New York City’s open data law (Local Law 11 of 2012), DoITT works with the Mayor’s Office of Data Analytics to add and make data from agencies across the City attainable on the NYC Open Data Portal. Making city data on the portal available for use by the public helps ensure New York City government is increasingly accountable and accessible to those it serves.

Beyond providing information to the public, these data sets serve as rich resources for developers, civic groups, and other users to build applications of their own. In addition, the City supplies APIs (application programming interfaces) through its Developer Portal, enabling the City to foster innovation and leverage talents beyond City government to create solutions for tough problems.

The City’s open data law outlines a number of key milestones through 2018:

NYC OpenData Portal

Currently, more than 1,400 datasets are available for free via the NYC Open Data portal on NYC.gov. The NYC Open Data Portal houses datasets from over 80 New York City-related entities including City agencies, Business Improvement Districts, elected officials’ offices, and more. This data includes 311 service requests, motor vehicle collisions, buildings permits, restaurant inspections, and real-time traffic speeds. This website is a core component of the City's open data efforts, underscoring the City’s revolutionary approach to storing and publishing City data in a searchable, sortable, and customer-friendly manner.

NYC Developer Portal

The NYC Developer Portal is a one-stop destination for New York City specific APIs, apps, and datasets, enabling the development of consumer grade apps. The NYC Developer Portal was established to be a central hub for engagement with the developer community to:
  • Provide a collection of APIs for City data that developers can use to create apps to improve the lives of New Yorkers and the way in which City government serves them.
  • Operate as a forum for developers to interact with the City about its public data, suggest ways to improve how the City presents its data, and find additional collaborators for their own civic projects.

Visit the Developer portal to view New York City apps and APIs.

NYC Big Apps Competition

In the summer of 2009, DoITT and the NYC Economic Development Corporation established the NYC BigApps Competition. [http://bit.ly/1mDOcxa] This annual competition challenges local entrepreneurs and developers to utilize NYC OpenData to create new and unique tools for public use. The program has resulted in the creation of hundreds of new applications by the public and for the public – at essentially no cost to taxpayers.

311 Open API

Open311 is a national program based in New York City that supports open standards around data exchange between 311 systems and non-government web and mobile applications. The City of New York is working with Open311 and other cities across the country to develop interoperable systems that will afford citizens greater access to data from 311 systems.

 

The City of New York released a content-inquiry application programming interface (API) through the NYC Developer Portal as part of Open311's efforts. The inquiry API supports content for services, facilities and a RSS feed of daily information.

Multi-City Data Sharing: Cities.data.gov

The City of New York is working with large jurisdictions across the country and the Federal Government to aggregate and share data. The circulation of municipal data enables data-driven decision making and analysis in a way never possible before.

Cities.data.gov is a new one-stop destination for searchable, sortable, and downloadable data. The website currently includes datasets from New York, Chicago, Seattle, San Francisco and the Federal Government. The unified data portal also provides links to download apps, details on civic challenges, and open data policies. This initiative promotes transparency in government while providing developers and the public with the tools to build innovative applications and platforms for their communities.
