Global AIDS Response Progress Reporting 2014 9 “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.” UNCLASSIFIED

  28. 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.

  30. 30. PLOS’ New Data Policy: Public Access to Data 30 … 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. UNCLASSIFIED
