a. Within one year of the effective date of this chapter and thereafter, the public data sets that agencies make available on the Internet shall be accessible through a single web portal that is linked to nyc.gov or any successor website maintained by, or on behalf of, the city of New York. If an agency cannot make all such public data sets available on the single web portal pursuant to this subdivision, the agency shall report to the department and to the council which public data set or sets that it is unable to make available, the reasons why it cannot do so and the date by which the agency expects that such public data set or sets will be available on the single web portal.
b. Such public data sets shall be made available in accordance with technical standards published by the department pursuant to section 23-505 of this chapter and shall be in a format that permits automated processing and shall make use of appropriate technology to notify the public of all updates.
c. Such public data sets shall be updated as often as is necessary to preserve the integrity and usefulness of the data sets to the extent that the agency regularly maintains or updates the public data set. The department shall preserve row data that is subject to permanent removal or replacement and shall create and preserve archival copies, or an archival compilation data set with data indexed to its time of preservation, of public data sets in accordance with the technical standards manual published by the department pursuant to section 23-505. If any public data set is available on the single web portal and another website maintained by or on behalf of the city or a city agency, when such public data set is updated on such city or city agency website, such public data set shall also be updated on the single web portal within ten days in accordance with the technical standards published by the department pursuant to section 23-505; provided that if any such public data set receives automated updates on such city or city agency website, such public data set shall be updated on the single web portal within one day of any such automated update. If there is a public data set for which such update schedule regularly cannot be met, the agency that maintains such public data set shall report to the department the reasons why it cannot meet such update schedule and the date by which the agency expects that it will be able to meet such schedule, and such information shall be disclosed in the compliance plan prepared pursuant to section 23-506.
d. Such public data sets shall be made available without any restrictions on their use provided that the department may require a third party providing to the public any public data set, or application utilizing such data set, to explicitly identify the source and version of the public data set, and a description of any modifications made to such public data set. Restrictions as used in this section shall not include measures required to ensure access to public data sets, to protect the single web site housing public data sets from unlawful abuse or attempts to damage or impair use of the web site, or to analyze the types of data being used to improve service delivery.
e. Such public data sets shall be accessible to external search capabilities.
f. Agencies shall review responses to freedom of information law requests that include the release of data to determine if such responses consist of or include public data sets that have not yet been included on the single web portal or the inclusion of which on the single web portal is not provided for in the compliance plan prepared pursuant to section 23-506. Each agency shall disclose in the update to such compliance plan the total number, since the last update, of such agency's freedom of information law responses that included the release of data, the total number of such responses determined to consist of or include a public data set that had not yet been included on the single web portal and the name of such public data set, where applicable, and the total number of such responses that resulted in voluntarily disclosed information being made accessible through the single web portal.
