Many Wikipedia language editions have large gaps in knowledge. We want to close these gaps by allowing to create and maintain content in one place and allow the Wikipedias to use this content if they choose so. This will allow more people to create, maintain, and read more knowledge in more languages.
In order to do this, we need to represent the content in a way that can be translated to many different natural languages. We do this by introducing a new Wikimedia project, Wikilambda, that allows to create, maintain, catalogue and evaluate functions as a new form of knowledge the communities work on. This will allow completely new use cases, and allow more people to share in more forms of knowledge.
The project proposal page leads to much more detail on the project. We are looking for feedback, supporting voices, questions, statements of opposition on the proposal talk page, and people to help with translating and disseminating the proposal page.
