Wikidata is a free knowledge base that can be read and edited by humans and machines alike. It is for data what Wikimedia Commons is for media files: it centralizes access to and management of structured data, such as interwiki references and statistical information. Wikidata contains data in every language supported by the MediaWiki software. Wikidata is a project of the Wikimedia Foundation: a free, collaborative, multilingual, secondary database, collecting structured data to provide support for Wikipedia, Wikimedia Commons, the other Wikimedia projects, and well beyond that.

CBPP Directory

The mission of this directory is to collect and typify digital platforms or projects that are Commons Based Peer Productions (CBPP). In short, CBPP means to produce collaboratively and provide access to resources under community governance. Currently, in this directory there are a hundred of cases that are based on collaborative forms of production. Projects that produce open sets of software, texts, images, videos, music or sounds, collaborative research projects that give access to all the data, projects that produce resources for public use and that also offer open methodologies, etc.


Arduino boards can be purchased pre-assembled or as do-it-yourself kits. Hardware design information is available for those who would like to assemble an Arduino by hand. It was estimated in mid-2011 that over 300,000 official Arduinos had been commercially produced

There are currently 385 Commons-Based Peer Production cases!
