Endangered Languages Awesome

There is no centralised list of open-source code that would be useful for documenting, conserving, developing, preserving, or working with endangered languages. According to some estimates, half of the 7,000~ currently spoken languages are expected to become extinct this century (Wikipedia). However, there is a lot of work by academics, independent scholars, organizations, communities, and individuals which goes towards stopping or slowing this trend. This list is intended to provide a central location to document those efforts.

Contribute

To edit this list, simply click here. If you would like to discuss anything at all related to this, please open an issue. Please edit the list, either using the link before or by submitting pull requests, if you know of any resource available that is not on this list.

For further examples please consider looking at examples in the example template file.

In general, please link directly to the resource or to the page describing the resource. The blurb after the link should be something short - the GitHub description generally works well, although the blurb may have to be written manually for non-GitHub links or for GitHub links which lack descriptions. Please make sure each link is on one line, to help with automatic alphabetization.

Definitions

Endangered languages are human languages that are in danger of extinction. This list also encompasses minority languages - languages which are spoken by a stable, but small, population (for example, Maltese or Hawai'ian); and low- or under-resourced languages, which are spoken by a significant population but under-represented on the web (for instance, Quechua). These languages share certain characteristics in common; the most pertinent is sparse data and a lack of resources, ranging from spell-checkers to grammars to machine translation corpora. Other under-resourced languages that do not fall under this list include constructed languages (for instance, Klingon or Na'vi), computer languages (for instance, Javascript or Lua), and extinct languages that are so sparse as to be rendered computationally irrelevant for most purposes (for instance, Tocharian).

Open Source "promotes a universal access via a free license to a product's design or blueprint, and universal redistribution of that design or blueprint, including subsequent improvements to it by anyone." (Wiki). This is important because money and resources allocated towards a language or project that are not open source is spent at the expense of possible extensibility elsewhere.
