hide from wikipedia the free encyclopedia practice of sharing knowledge publicly and reusably open knowledge is interpreted broadly including the production of open content such as open data open source software open education resources and open access as well as practices such as open research explainer video what is open knowledge a short history of copyright open knowledge or free knowledge is knowledge that is free to use reuse and redistribute without legal social or technological restriction 1 open knowledge organizations and activists have proposed principles and methodologies related to the production and distribution of knowledge in an open manner the concept is related to open source and the open definition whose first versions bore the title open knowledge definition is derived from the open source definition history edit early history edit similarly to other open concepts though the term is rather new the concept is old one of the earliest surviving printed texts a copy of the buddhist diamond sutra produced in china around 868 ad contains a dedication for universal free distribution 2 in the fourth volume of the encyclopédie denis diderot allowed re use of his work in return for him having used material from other authors 3 twentieth century edit in the early twentieth century a debate about intellectual property rights developed within the german social democratic party a key contributor was karl kautsky who in 1902 devoted a section of a pamphlet to intellectual production which he distinguished from material production communism in material production anarchy in the intellectual that is the type of a socialist mode of production as it will develop from the rule of the proletariat in other words from the social revolution through the logic of economic facts whatever might be the wishes intentions and theories of the proletariat 4 40 this view was based on an analysis according to which karl marx s law of value only affected material production not intellectual production with the development of the public internet from the early 1990s it became far easier to copy and share information across the world the phrase information wants to be free became a rallying cry for people who wanted to create an internet without the commercial barriers that they felt inhibited creative expression in traditional material production 5 digital rights activists aim to enable related concepts including access to data produced with public funds and freedom of expression online 6 wikipedia was founded in 2001 with the ethos of providing information which could be edited and modified to improve its quality the success of wikipedia became instrumental in making open knowledge something that millions of people interacted
