New Reference Database: Net Data Directory (Sources of Data About the Internet)

The following new, searchable, and browsable database was launched today by the Berkman Center at Harvard.

We’re excited to see it. Potentially, VERY useful and needed. Here’s to more entries moving forward and once again, kudos, Berkman!

Entries can be keyword searched as well as browsed by topic and geography.

From an Introductory Blog Post:

The Berkman Center for Internet & Society is delighte2016-06-02_14-31-51d to announce the launch of the Net Data Directory, a free, publicly available, searchable database of different sources of data about the Internet. The directory is intended to make finding useful quantitative data about a broad range of Internet-related topics—broadband, cybersecurity, freedom of expression, and more—easier for researchers, policymakers, journalists, and the public.

“A large number of organizations are producing data about all different facets of the Internet,” said Fernando Bermejo, Berkman Center Faculty Associate and founder of the project. “However, it is not always easy to identify those sources and obtain the data. We hope the Net Data Directory will help anyone interested in knowing about the current state of the Internet to find the data they need in order to make informed decisions, produce insightful research, or simply learn something new about the online world.”

Records in the directory include the name of the data source, a short description of the available data, and a link. Data sources are tagged both by geographic coverage (including global, regional, and country-level tags) and by topic (such as broadband, cybersecurity, and social media). Users can search, sort, and filter records within this database to identify datasets relevant to their work. The vast majority of datasets within the directory are themselves open and publicly available.

The Net Data Directory currently contains over 150 data source records, ranging from the Interactive Advertising Bureau’s regular reports on online advertising revenue to the European Union’s Eurobarometer, which publishes data collected through public opinion surveys on a wide range of issues including data protection and digital markets; Tiobe, which offers a monthly index of the popularity of different programming languages; the Economic and Social Commission for Asia and the Pacific’s digital data explorer; the Digital Attack Map, a collaboration between Google Ideas and Arbor Networks that provides daily information on DDoS attacks worldwide; AFRINIC’s set of statistics on IPv4, IPv6, and AS numbers in Africa and the Indian Ocean; the OECD’s Broadband Portal and other ICT indicators; and many more. Records are maintained by researchers at the Berkman Center; users can also suggest new data sources through the NDD website.

The Net Data Directory is a partner of Internet Monitor, a research project based at the Berkman Center that aims to evaluate, describe, and summarize the means, mechanisms, and extent of Internet content controls and Internet activity around the world.
