Hi there!

I should know this but I wanted to check! I’m working with a client and we’ve a ticket about affiliation information being limited to 5 affiliations connected to a contributor - I didn’t think this was the case from looking at the .xsd - are there any limitations on the number of affiliatons/organisations that can be associated with one author?

Many thanks,  
Rachael

Hi! Schema versions 5.3.1 and up don’t limit the number of author affiliations, but earlier versions limit to 5.

In which case, thank you for solving a Trello ticket mystery for us! : )
