  • 2019
  • Data Counts! and Open Data Ambassadors Pilot of Data Counts! initiative, a collaboration with BetaNYC and the Queens Public Library, which led to the creation of a cohort of volunteer “Open Data Ambassadors” teaching people from every community board in Queens about Open Data and the US Census.
  • Co-designing the Future of NYC's Open Data Workshop After an earlier public survey campaign to better recognize New Yorker’s information needs in all five boroughs, the Open Data Team convened a two-day co-design workshop where more than 60 participants addressed common challenges, surfaced opportunities, and helped prioritize key initiatives for the next decade of NYC Open Data. This work was compiled into the 2019 Strategic Plan.
  • Examination & Verification Final Report NYC Open Data published a report concluding its series of three annual examinations of City agencies, pursuant to Local Law 8 of 2016, Open Data Examination and Verification. The examinations were intended to improve agency compliance with the Open Data Law by creating a systematic way to locate datasets that may have been omitted in agencies’ self-reported Open Data compliance plans. This effort has since been used to inform the Open Data compliance reporting process.
