Jersey City Open Data Policy
Data Collection Process
All Jersey City government agencies, departments, divisions, offices, and other related entities
shall, make a good faith effort to build robust data recording and management systems and
processes. These systems may vary from manual collection processes to automated feeds
transmitting data directly from the point of capture to the Data Portal.
The Office of Innovation is committed to working with all parties to ensure any data collection
processes do not substantially inhibit workflow or other daily operations.
Data Included, Exemptions and Restrictions
All data (see below definitions) capturing relevant information about government operations and
activities shall be included, with the following exceptions:
The City shall be exempt from publishing any data that would be exempt from disclosure based on
any exemption set forth in the New Jersey Open Public Records Act, N.J.S.A. 47:1A-1 et seq. or any
other exemptions required by law.
The Data Portal shall never include:
a. Personally identifiable information of government employees or any other people
b. Information that reflects the internal deliberative process of a department or
departments, including but not limited to negotiating positions, future procurements, or
pending or reasonably anticipated legal or administrative proceedings
c. Proprietary applications, computer code, software, operating systems or similar
materials
d. Attorney-client work product or internal discussions in anticipation of litigation.
Data shall never be deleted from the Data Portal unless it is incorrect or incomplete.
A list of all published data sets shall be readily available at all times on the Data Portal.
Data Structure, Format, and Quality
Data shall be produced and published in non-proprietary, searchable, sortable, platformindependent,
machine readable format(s) consistent with applicable open data standards and
practices.
Data shall be able to be viewed directly on the portal and available for export through the Portal in
.pdf, .xml, .csv and/or tabular formats.
Application Programming Interface (API) documentation (see below definitions) for automated
downloads shall be made available on the Data Portal.
WWW.JERSEYCITYNJ.GOV WWW.INNOVATEJERSEYCITY.ORG
All available metadata and metadata documentation (see below definitions) shall be made public
on the Data Portal.
Data shall be searchable through the Data Portal either by keyword search, browsing by type of
operation, or by scrolling through lists or carousels of data sets and analyses.
Maintenance and Management
The City responsible shall develop and manage appropriate Exchange, Transfer, and Loading
(ETL) processes that allow for any edits to the data to make it suitable to publication on the Data
Portal. The City shall also ensure published data remains accurate and aligns with the policy set
forth here.
Publishing and Updates
Data shall be refreshed and updated at reasonable intervals when new data becomes available.
Data sets may be updated weekly, daily, or in real time as is reasonable given the type of data,
technology capacity, and amount of data produced. The preferred maximum update interval is
one month. Regardless of data update intervals, each data set shall be reviewed for accuracy at
least once annually by the Office of Innovation.
Public Use of Data
The City shall not place any restrictions on third-party reuse of data. The City shall not provide to
third parties any copies, records or logs of the identities or IP addresses of individuals accessing
the data or the Portal, with the exception of a valid law enforcement purpose.
Definitions (based on the White House Project Open Data):
APPLICATION PROGRAMMING INTERFACE (API): Software and/or other code/programming
elements and specifications that describe how programs and software communicate and share
data and other relevant information.
CSV: A comma separated values (CSV) file is a computer data file used for implementing the tried
and true organizational tool, the Comma Separated List. The CSV file is used for the digital storage
of data structured in a table of lists form. Each line in the CSV file corresponds to a row in the
table. Within a line, fields are separated by commas, and each field belongs to one table column.
CSV files are often used for moving tabular data between two different computer programs (like
moving between a database program and a spreadsheet program).
WWW.JERSEYCITYNJ.GOV WWW.INNOVATEJERSEYCITY.ORG
DATA: A value or set of values representing a specific concept or concepts. Data become
“information” when analyzed and possibly combined with other data in order to extract meaning,
and to provide context. The meaning of data can vary depending on its context. Data includes all
data. It includes, but is not limited to, 1) geospatial data 2) unstructured data, 3) structured data,
etc.
DATASET: named collection of related, digitally-stored data with the collection containing
individual Data units organized or formatted in a specific and prescribed way, often in tabular
form, and accessed by a specific access method that is based on the Dataset organization, but not
including any Data that is protected from disclosure under applicable Federal or State law.
DEPARTMENT: any subdivision within the municipal government, and any bureau or office under
it, which performs a function of municipal government.
JSON: JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for
humans to read and write. It is easy for machines to parse and generate. It is based on a subset of
the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is
a text format that is completely language independent but uses conventions that are familiar to
programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and
many others. These properties make JSON an ideal data-interchange language.
MACHINE-READABLE FILE: Refers to information or data that is in a format that can be easily
processed by a computer without human intervention while ensuring no semantic meaning is lost.
METADATA: To facilitate common understanding, a number of characteristics, or attributes, of
data are defined. These characteristics of data are known as “metadata”, that is, “data that
describes data.” For any particular datum, the metadata may describe how the datum is
represented, ranges of acceptable values, its relationship to other data, and how it should be
labeled. Metadata also may provide other relevant information, such as the responsible steward,
associated laws and regulations, and access management policy. Each of the types of data
described above has a corresponding set of metadata. Two of the many metadata standards are
the Dublin Core Metadata Initiative (DCMI) and Department of Defense Discovery Metadata
Standard (DDMS). The metadata for structured data objects describes the structure, data
elements, interrelationships, and other characteristics of information, including its creation,
disposition, access and handling controls, formats, content, and context, as well as related audit
trails. Metadata includes data element names (such as Organization Name, Address, etc.), their
definition, and their format (numeric, date, text, etc.). In contrast, data is the actual data values
such as the “US Patent and Trade Office” or the “Social Security Administration” for the metadata
called “Organization Name”. Metadata may include metrics about an organization’s data including
its data quality (accuracy, completeness, etc.).
OPEN DATA PORTAL/DATA PORTAL: the electronic software platform where Datasets are hosted
and made available to the public.
OPEN DATA STANDARD: the generally accepted technical standards developed to provide
consistency of data presentation in Open Data Portals.
WWW.JERSEYCITYNJ.GOV WWW.INNOVATEJERSEYCITY.ORG
XML: Extensible Markup Language (XML) is a flexible language for creating common information
formats and sharing both the format and content of data over the Internet and elsewhere. XML is a
formatting language recommended by the World Wide Web Consortium (W3C).
