Wikimedia Indonesia via Wikimedia Netherlands asks for help to volunteers to transcribe the letters in Dutch Wikisource as most of the letters are in Dutch languages. The transcribing process is required before translating those documents into Bahasa Indonesia. One of the transcribing volunteers is WeeJeeVee, who is fascinated in doing transcribing text to Dutch Wikisource and has set up a page about this activity in Dutch Wikisource.
Another volunteer involved in this activity is Sersan Mayor Kururu, an Indonesian Wikipedian. She is a university student in Yogyakarta and has knowledge in the Dutch language. Sersan Mayor Kururu has helped Wikimedia Indonesia for the past five months in doing letter conservation and digitization.
Started from January 2018, the letters were translated into Bahasa Indonesia from Dutch, English, and Javanese languages to provide what the letters say to people widely, especially for the people in Indonesia. This effort will continue until the end of February and done by Meursault2004, a senior Wikipedian from Indonesia.
@Rachmat04: It's really great to see you reporting the digitization work you have been doing with your partners! I hope you keep reporting out the collaborations with libraries and museums, Astinson (WMF) (talk) 20:20, 20 February 2018 (UTC)
@Astinson (WMF): Hello Astinson. I'm glad you are interested to hear more about our collaborations in Indonesia. Surely, I will keep you updated about our GLAM activities as best as I can. Thank you! ···🌸Rachmat04·☕ 00:19, 21 February 2018 (UTC)
