Yes, this is a valid question, we had a project even by bafu where we prepared a version specifically for openLCA, and a version for SimaPro as well, but from what I understand some ecoinvent datasets that are used are considered as precious and thus ecoinvent and uvek / bafu are still in discussion how to do it. I hope this solves soon. Why it is permitted to distribute the SimaPro files but we can not distribute files for openLCA (ensuring that users have an ecoinvent license) is beyond my understanding.
edit: the zolca file is for openLCA I see now..
