Mirror siteMirror sites or mirrors are replicas of other websites. The concept of mirroring applies to network services accessible through any protocol, such as HTTP or FTP. Such sites have different URLs than the original site, but host identical or near-identical content. Mirror sites are often located in a different geographic region than the original, or upstream site. The purpose of mirrors is to reduce network traffic, improve access speed, ensure availability of the original site for technical or political reasons, or provide a real-time backup of the original site.
YAGO (database)YAGO (Yet Another Great Ontology) is an open source knowledge base developed at the Max Planck Institute for Informatics in Saarbrücken. It is automatically extracted from Wikipedia and other sources. As of 2019, YAGO3 has knowledge of more than 10 million entities and contains more than 120 million facts about these entities. The information in YAGO is extracted from Wikipedia (e.g., categories, redirects, infoboxes), WordNet (e.g., synsets, hyponymy), and GeoNames. The accuracy of YAGO was manually evaluated to be above 95% on a sample of facts.

Web template systemA web template system in web publishing allows web designers and developers work with web templates to automatically generate custom web pages, such as the results from a search. This reuses static web page elements while defining dynamic elements based on web request parameters. Web templates support static content, providing basic structure and appearance. Developers can implement templates from content management systems, web application frameworks, and HTML editors.
Definition of Free Cultural WorksThe Definition of Free Cultural Works evaluates and recommends compatible free content licenses. The Open Content Project by David A. Wiley in 1998 was a predecessor project which defined open content. In 2003, Wiley joined the Creative Commons as "Director of Educational Licenses" and announced the Creative Commons and their licenses as successors to his Open Content Project. Therefore, Creative Commons' Erik Möller in collaboration with Richard Stallman, Lawrence Lessig, Benjamin Mako Hill, Angela Beesley, and others started in 2006 the Free Cultural Works project for defining free content.
Participatory cultureParticipatory culture, an opposing concept to consumer culture, is a culture in which private individuals (the public) do not act as consumers only, but also as contributors or producers (prosumers). The term is most often applied to the production or creation of some type of published media. Recent advances in technologies (mostly personal computers and the Internet) have enabled private persons to create and publish such media, usually through the Internet.
Zero-ratingZero-rating is the practice of providing Internet access without financial cost under certain conditions, such as by permitting access to only certain websites or by subsidizing the service with advertising or by exempting certain websites from the data allowance. Commentators discussing zero-rating present it often in the context of net neutrality. While most sources report that use of zero-rating is contrary to the principle of net neutrality, there are mixed opinions among advocates of net neutrality about the extent to which people can benefit from zero-rating programs while retaining net neutrality protections.
