The NYC OpenData portal supports most modern web browsers. The web application permits the listing, viewing, exporting, embedding, filtering, visualizing, personalizing, commenting on, and rating of public data sets.
The NYC OpenData portal supports a generic API that permits access to all published data sets in a similar manner. The API is based upon the Socrata Open Data API (SODA).
In 2009, the U.S. Government defined an open file format as “one that is platform independent, machine readable, and made available to the public without restrictions that would impede the re-use of that information.” The NYC OpenData portal supports the public downloading of data sets in the following formats:
| Type | Media | Description |
|---|---|---|
| CSV | Text | Comma-separated values |
| JSON | Text | JavaScript Object Notation |
| Binary | Portable Document Format | |
| RDF | Text | Resource Description Framework |
| RSS | Text | RDF Site Summary/Really Simple Syndication (Note: each row is represented as a separate item, but each item’s description field contains an HTML table with the column names and row values) |
| XLS | Binary | Microsoft Excel |
| XLSX | Binary | Microsoft Excel Open XML |
| XML | Text | Extensible Markup Language |
In addition, some data sets may also have the following formats available:
| Type | Media | Description |
|---|---|---|
| ZIP | Binary | Typically contains a shapefile set (SHP, SHX, DBF) (Geographic data sets only), or a collection of multiple files which are all part of the same data set. (Note: this is usually provided within a compressed archive) |
