As I have started recording my family history using evidence based methods in Gramps I've noticed that it is very flexible (too flexible?). I worry that the method in which I record data might seem sensible at first but after running reports or exporting my data I will notice issues with my data that will require bulk editing because I wasn't using a Gramps convention. For example, I'm not sure if it is better to record the details of a marriage in an event or family object and how that will affect GEDCOM exporting.
What are some of the major conventions of entering data into Gramps and what resources are available to help me figure out how to store data in the most 'future-proof' way?
