Brooklyn Open Data Licensing - City Terms & Bylaws

Finding authoritative licensing terms for open data generated or hosted by Brooklyn, New York requires checking the City of New York’s official open-data portal and the municipal office that manages it. Many Brooklyn datasets are published through NYC Open Data; each dataset page or the portal’s Terms of Use should be your first stop for licensing, permitted uses, and attribution requirements. This guide explains where to look on official pages, who enforces terms, how to report problems, and practical steps to confirm reuse rights.

Where to look first

Start on the NYC Open Data portal dataset page: licensing or metadata fields often name the license or link to terms. If a dataset lacks explicit license metadata, consult the portal’s general Terms of Use and the Department of Information Technology and Telecommunications (DoITT) open-data policy for portal-wide rules. When the dataset notes a third-party source or specific license, follow that link and check the original publisher’s terms.

Common locations on a dataset page:

• License or Rights field in the dataset metadata.
• “About” or source notes describing origin and restrictions.
• Dataset contact or owner listed on the dataset page.

For portal-wide rules and standard terms see the NYC Open Data Terms of Use (Terms of Use)^[1] and the City’s DoITT open-data guidance (DoITT open data)^[2].

Penalties & Enforcement

Official portal terms typically set conditions for acceptable use, attribution, and disclaim liability; they do not usually set criminal penalties but may reserve civil remedies or termination of access. Specific monetary fines for misuse of open-data content are generally not stated on the portal terms pages; see notes and citations below.

• Fines: not specified on the cited page for portal licensing terms; see the Terms of Use for contractual remedies and disclaimers.^[1]
• Escalation: the Terms of Use typically describe access suspension or revocation for breaches but do not list graduated monetary penalties; not specified on the cited page.^[1]
• Non-monetary sanctions: access suspension, requirement to remove derivative works, or other civil actions may be available per the Terms of Use; exact remedies are not itemized as fixed penalties on the portal page.^[1]
• Enforcer: the Department of Information Technology and Telecommunications (DoITT) administers NYC Open Data operations and is the primary contact for portal issues; policy and portal administration are described on DoITT pages.^[2]
• Inspection and complaints: report suspected license violations or inaccurate metadata to the dataset contact listed on the dataset page and to DoITT or the city contact points listed in the portal documentation; see Help and Support / Resources below.
• Appeal / review: procedures for appeal or dispute resolution are not specified as formal timelines on the portal Terms of Use; consult the Terms of Use or contact DoITT for guidance—time limits are not specified on the cited pages.^[1]
• Defences and discretion: permissions, fair use, or direct agreements with dataset owners may be recognized; the portal terms allow site administrators discretion in enforcement but do not enumerate statutory defenses on the Terms page.

Applications & Forms

There are no standard city forms to “apply” for an open-data license on the portal; licensing is set either by the portal Terms of Use or by the dataset owner’s stated license. If you need a formal license or permission, contact the dataset owner listed on the dataset page or DoITT for guidance. The NYC Open Data Terms of Use and DoITT pages do not publish a dataset-license application form on the cited pages.^[1][2]

How to verify a dataset’s license

1. Open the dataset page on NYC Open Data and read the "License" or "Rights" metadata field.
2. Follow any license link to the original license text; if it points to a third-party publisher, check that publisher’s official license page.
3. If license metadata is missing or ambiguous, use the dataset contact listed on the page to ask for clarification and a written statement of reuse terms.
4. If the issue is unresolved, contact DoITT or submit a complaint via NYC 311 or DoITT contact channels (see Resources).

Common violations

• Failing to attribute when the license requires attribution.
• Republishing data contrary to a dataset-specific restriction (e.g., noncommercial-only terms).
• Assuming portal-wide terms apply when the dataset indicates a different license or third-party restriction.

FAQ

The dataset owner listed on the dataset page or the portal Terms of Use sets the applicable license; always check dataset metadata first.
