API - Map Host Item to Template item

[artrune]

I'm trying to find a way to map a specific host item to the item it comes from (The template) I originally had the approach of checking the item keys in the templates that the host is a member of and I can do the mapping like that, no problem.

The issue I have with that approach is that the item prototype keys are not the same in the templates and in the specific host item.

Is there a specific way to get an item parent (The item in the template) or a pointer that points a specific item to its parent template?

My ultimate goal is to store metadata related to the parent item (And have it propagate to the instance items, the actual metrics in hosts) but there doesn't seem to be a place other than description to store it, and using the description is not an option.
being able to map them solves the issue because then i can store my data wherever i like as long as i have a mapping.

Anyone with any clues of this?

Still haven't found a way and would probably use any insight from anyone! thanks.
