The German chapter of the international Wikimedia movement, Wikimedia Deutschland, is starting the development of a new Wikimedia project, called Wikidata. Wikidata will provide a collaboratively edited database of the world's knowledge. Its first goal is to support the more than 280 language editions of Wikipedia with one common source of structured data that can be used in all articles of the free encyclopedia.
For example, with Wikidata the birth date of a person of public interest can be used in all Wikipedias and only needs to be maintained in one place. Moreover, like all of Wikidata's information, the birth date will also be freely usable outside of Wikipedia. The common-source principle behind Wikidata is expected to lead to a higher consistency and quality within Wikipedia articles, as well as increased availability of information in the smaller language editions. At the same time, Wikidata will decrease the maintenance effort for the tens of thousands of volunteers working on Wikipedia.
The CEO of Wikimedia Deutschland, Pavel Richter, points out the pioneering spirit of Wikidata: "It is ground-breaking. Wikidata is the largest technical project ever undertaken by one of the 40 international Wikimedia chapters. Wikimedia Deutschland is thrilled and dedicated to improving data management of the world's largest encyclopedia significantly with this project."
Besides the Wikimedia projects, the data is expected to be beneficial for numerous external applications, especially for annotating and connecting data in the sciences, in e-Government, and for applications using data in very different ways. The data will be published under a free Creative Commons license.
The initial development of Wikidata is being funded with a major donation of 1.3 Million Euros, granted in half by the Allen Institute for Artificial Intelligence [ai](2). The institute supports long-range research activities that have the potential to accelerate progress in artificial intelligence. It was established in 2010 by Microsoft co-founder Paul G. Allen, whose contributions to philanthropy and the advancement of science and technology span more than 25 years.
One quarter of Wikidata's initial funding is donated by the Gordon and Betty MooreFoundation through its Science program.
Wikidata will be developed in three phases. The first phase is expected to be finished by August 2012. It will centralize links between the different language versions of Wikipedia in one place. In the second phase, editors will be able to add and use data in Wikidata. The results of the second phase are scheduled to be released in December 2012. The third and final phase will allow for the automatic creation of lists and charts based on the data in Wikidata. This will close the initial development process for Wikidata.
Wikimedia Deutschland will perform the initial development, and then hand over operation and maintenance of the project to the Wikimedia Foundation. This is planned to be achieved by March 2013. The team of eight developers is being led by Dr. Denny Vrandecic. He changed from the Karlsruhe Institute of Technology to Wikimedia Deutschland and is, together with Dr. Markus Krotzsch, of the University of Oxford, co-founder of the Semantic MediaWiki project, which has pursued the goals of Wikidata for the last few years. The proposal for Wikidata was developed with financial support by the EU project RENDER, which also involves Wikimedia Deutschland as a use-case partner.
