Dear all, I would like your help regarding the use of the bf:Generation class. This class seems to me like an event class that may be used to document the details of a reproduction process. What I do not get is how one can connect the original bf:Instance to the reproduced one using the bf:Generation <http://id.loc.gov/ontologies/bibframe.html#c_Generation> class. The use of an original bf:Instance in a reproduction process can be represented with the following path: bf:Instance-bf:generation-bf:Generation. Is there a property to relate the bf:Generation class instance to the reproduced bf:Instance? Due to domain and range restrictions the bf:generation <http://id.loc.gov/ontologies/bibframe.html#p_generation> property cannot be used (Domain: Instance, range:Generation). Thanks in advance and greetings from Greece Sofia Zapounidou <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Απαλλαγμένο από ιούς. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
