What is the name of the tool?
Tool Class
To what "family" does the tool belong? Pick as many categories as are appropriate. EG: Data Collection, Security, etc. The wiki will automatically create a link to the relevant tool class.
DemTools, Data Visualization, Mapping, Data Aggregation, Data
Who made the tool? Sometimes the tool name and the developer name are the same, and sometimes, they are different.
Date Created
What was the date when the tool was first launched?
Still Maintained?
Do the developers of the tool continue to work on it, adding features and fixing problems?
Open Source?
Is the tool's source code original source code freely available and may it be redistributed and modified? (This makes it possible for users to employ the tool for free, with some technical effort.)
Pick the platforms on which the user would primarily use the tool. Be as selective as possible. If a tool works mainly in the browser, select "Web". If the user can technically load the interface on a smartphone but have a very poor experience, do not select "Android" or "iOS". "Mac" and "PC" are for apps that must be installed to a machine in order to run, as opposed to running from a browser.
What is the main website where a user can learn more about the tool? (Remember to include "http://)."
Payment Structure
How, if at all, does a user pay to use the tool. Select all that apply: "Free" if there are components of a service that can be used for free; "Paid" if payment is required (either one-time, or at a given rate upon use) for use of the tool's full functionality; "subscription" if a monthly payment is required.
free, subscription
Languages Supported
What languages does the app's interface support? Note: some apps allow users to communicate in other languages but require the user to use an English language interface. In this case, the app is considered only to support "English".
Skill Level Needed
  • Beginner - The tool has a simple interface that assists the user, either through automatic processes or simple guides, in working with the tool. The user is able to do most things that they need to do without knowledge of advanced concepts, like code.
  • Intermediate - The tool allows the user to perform many tasks without knowledge of advanced concepts, but about an equal amount of functionality requires advanced knowledge. Some training may be required to use the tool.
  • Advanced - The tool requires advanced knowledge or training in order to use most of its functionality.

Tool Description

DKAN is a comprehensive data management warehouse developed by NuCivic which can publish open data and create compelling map and graph-based visualizations. It is freely available from NuCivic's GitHub Repository Experience in Linux systems administration, Drupal and web server management is needed for setup and maintenance. NDI provides software-as-a-service hosting for this and other DemTools on our DemCloud servers. NuCivic also offers hosted options.

DKAN extensions for the typical needs of a civic group in the developing world are available on GitHub repository. Installation, securing and maintenance requires someone with experience in Linux and web server management. NDItech provides software-as-a-service hosting for this and other DemTools on our DemCloud servers.

Governments and civic organizations are increasingly embracing the open data movement and with it the prospect of unprecedented public transparency. However, organizations often need a sophisticated data repository to make information accessible to citizens and civic organizations, particularly in formats that can be accessed by other computers via application programming interfaces (APIs). Raw data, even when publicly shared, is not easily understood, and needs to be turned into data-driven stories to be useful to the public in holding institutions to account or assisting policymakers. The DKAN DemTool, developed by NuCivic, helps tackle these problems. Government organizations, journalists, policymakers or civic groups can create searchable, indexed public repositories of information compatible with open data standards. Data analysts and visual storytellers can then tap that information to create charts, graphs, maps and web pages to wrap raw numbers in powerful visualizations that illuminate meaning and have impact.

Publicly Sharing Open Data, Maps and Visualizations

DKAN was designed for groups who want to share data with the world in open, public, machine-readable formats, or generate maps, charts and other visualizations off of the data. This data may be their own - budgets from a ministry or survey information from a civil society organization (CSO’s) members - or it may be other information that they’ve aggregated from sources or scraped from public web sites. The end goal of such a data portal is to help increase understanding of complex information-centric topics, which can lead to political accountability and better policy-making. Remember that audiences are rarely the general public, who have little appetite for spreadsheets or even stacked bar charts; they are usually intermediary groups such as CSOs, journalists, or even public officials and their staffs who affect either public opinion or government policy. Groups are better advocates for their priority issues with information that is readily available and able to be analyzed rapidly without a high level of technical skills.

DKAN’s design allows publicly shared large open datasets with standard open-data APIs. Organizations who want to build open data platforms that are fully compatible with the gigantic systems used by the White House or World Bank - and the large civic software development community around them - will find DKAN useful.

Maps and graphs can often tell a story more effectively than a table of numbers; DKAN gives the ability to create colorful, customizable visualizations that can be published directly, shared on social media or embedded in other web sites. With digitized boundaries of as countries or provinces maps can be automatically generated to look for geographic trends, reducing the need for complicated and often costly GIS software.

DKAN allows you to create a variety of visualization types so you can select the most effective graphical depictions to communicate your findings. Color-gradient maps can highlight highlight differences between regions, while a range of powerful chart and graph generators can show changes over any number of variables.


What Makes This Tool Different from Others in its Class?

Because DKAN is relatively simple to use, it can also be a powerful tool for simple internal data warehousing or visual analysis. Once an organization knows how to manage data in DKAN, it can be a good system for archiving old data sets for future reference, or a simple way to generate the same sorts of charts and graphs that one could in Excel - but automatically shareable online and dynamically updated as information changes.
