We're importing the EHR study nightly from a file dump. If I want to define custom metadata for lists or datasets, I can do so in list.xml or datasets.xml. However, where would I define custom metadata for either the StudyData or Participant tables (the automatically created ones)?

Specifically, I'd like to define a min width for the description field in StudyData and add a bunch of aliases to the Participant table.

Also, if we have a custom noun in our study, how does this impact metadata? For example, the particiapnt table is actually called 'animal' in our study. Should the metadata reflect this? In our dataset XML file, all the tables refer to participantId, even though it will be called 'animal' in our study, so perhaps this translation happens later?
