“To facilitate data integration and
analysis, geographic markers for data
should be maintained with indicators
at the appropriate level of precision
and using standardized geographic
references and naming conventions...
Attaching geographic information to
the more granular data that compose
aggregate indicators can enable a
wide array of analysis, such as
geographic coverage of services,
spatial distribution of human
resource and expenditures, and the
estimation of change over time
for small areas.”

“The three principles of transparency, participation, and collaboration form the
cornerstone of an open government. Transparency promotes accountability by
providing the public with information about what the Government is
doing. Participation allows members of the public to contribute ideas and
expertise so that their government can make policies with the benefit of
information that is widely dispersed in society. Collaboration improves the
effectiveness of Government by encouraging partnerships and cooperation
within the Federal Government, across levels of government, and between the
Government and private institutions.”
1. Publish Government Information Online
2. Improve the quality of USG information
3. Create and Institutionalize a Culture of Open Government
4. Create an Enabling Policy Framework for Open Government

… We are now revising our data-
sharing policy for all PLOS
journals: authors must make all
data publicly available, without
restriction, immediately upon
publication of the article.
Beginning March 3rd, 2014, all
authors who submit to a PLOS
journal will be asked to provide a
Data Availability Statement,
describing where and how others
can access each dataset that
underlies the findings. This Data
Availability Statement will be
published on the first page of
each article.

  • 28. “The three principles of transparency, participation, and collaboration form the cornerstone of an open government. Transparency promotes accountability by providing the public with information about what the Government is doing. Participation allows members of the public to contribute ideas and expertise so that their government can make policies with the benefit of information that is widely dispersed in society. Collaboration improves the effectiveness of Government by encouraging partnerships and cooperation within the Federal Government, across levels of government, and between the Government and private institutions.” 1.
