Suggestions for organizing an ingest structure

[Anthony Weaver]

We are working on a search index related to images captured from trail cameras.  We have an initial structure in place and working that captures metadata like location, and what was detected (animal, person, animal and person).  

We just recently added some additional processing that now includes species classification such as deer, turkey, etc.) and we'd like to add this new information to our metadata structure something like classification: deer.

Where we're stuck is that sometimes there are multiple and different classifications in the same image and I'm not sure the best way to add both into the search index.  For some reference here our subject is the image file and the content includes, detection, image_date, and location and so if an image (or subject) has multiple classifications I'm not sure how to add both entries since they point to the same subject.

Thank you for your help
