This proposal consists of two parts: Abstract Wikipedia and Wikilambda.
The goal of Abstract Wikipedia is to let more people share in more knowledge in more languages. Abstract Wikipedia is an extension of Wikidata. In Abstract Wikipedia, people can create and maintain Wikipedia articles in a language-independent way. A Wikipedia in a language can translate this language-independent article into its language. Code does the translation.
Wikilambda is a new Wikimedia project that allows to create and maintain code. This is useful in many different ways. It provides a catalog of all kind of functions that anyone can call, write, maintain, and use. It also provides code that translates the language-independent article from Abstract Wikipedia into the language of a Wikipedia. This allows everyone to read the article in their language. Wikilambda will use knowledge about words and entities from Wikidata.
This will get us closer to a world where everyone can share in the sum of all knowledge.
