Hi @Astinson_WMF and thank you for your motivation. I am aware that it is not that easy to take into account each and every projects in the wikiverse, especially when there is no local liaison. So, I made a Humanism project in French Wiktionary, describing briefly your initiative and drafting some directions.
I found most of the texts in Wikisource, but I am not sure for the Universal Declaration of Human Rights for Children and Youth you mentioned. If it is not yet transcribed in Wikisource in several languages, I suggest you add it in the scope of this project.
I haven’t start a dashboard yet, I am waiting for some people to aggregate to the project, and I don’t want to do all the preparation alone. Also, I haven’t followed your guidelines at first, to do a project Wiktionary-based as we do usually, and that means with a cheap design and mostly a list of pages and suggestions. I may add some template later on.
It is not that easy to identify the more accurate words to include in this initiative, but it’s quite interesting
