Over the last few weeks, I have assembled a list of (mostly professional) go players, some basic biographical information (date of birth/death, rank progression) and of different spellings of their names in different languages.
There are several reasons why I think this list will be useful:
The data is openly available (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication), and I hope that others will have more ideas how to put it to good use. You can download the data in JSON format. There is also a REST API to access that data.
Contributions are welcome! There are probably quite a few errors in the data (erroneous spellings, wrong dates, ...), and definitively many pieces of information could be added on top of what I have so far.
Thanks are due to Andries Brouwer, Rémi Coulom, John Fairbairn and Mace Lee for useful suggestions and/or permission to use data from their projects.
