Dear Michael, thanks again for your question and request. I hope that more members of this list will share their thoughts about this.
I guess no one on the list were so ready for this kind of question, we have sort of moved slowly towards a moment when we think we are so many that we can start to look into next step, so far we were just discussing and discussing.
Your question is interesting relevant, and should have had a much better feedback, than those weeks without even an answer.
Lets bring your request a further step, so we can soon move it to the meta pages, and discuss openly.
I have to admit, I was not totally sure about your question, and maybe this goes for others, would you mind tell us more about your plans with this and anything more you want to share. It sounds like a tool, connected to Wikidata, which already sounds very good for a Wikimedia genealogy tool. you may actually turn up with your request in the perfect moment, where technical issues needs to be discussed, we were simply not there, but I guess that the group members will just consider each and every step towards the vision of a wikimedia genealogy website as positive, why your question may actually push us all into next step..
Please fill us in a bit more, and keep in mind, that most users on the list are not programmers, why technical details, may be needed to be presented in an easy way to understand.
I will be excited to get some input from you all on this list, as well as weather we need to wait more, or should go to next step, and start to creat the user group, in order to contact the wikimedia for further questions to move on with the project.
