We haven't yet fully figured out yet, nor agreed, on data modeling for those cases where a Commons file shows a specimen. Basically, an SDC variant of the Template:Specimen Wikitext template.

In some cases, the specimen will be held in a cultural institution and will hence also be a collections item with corresponding metadata - think collection info, inventory number...

Let's talk about proposals and agree upon a solution for this, which can then also be used as a template / best practice in upload tools, and can be used for the creation of simplified/minimal Lua-driven SDC-powered infobox templates (in particular Lua-fication of Template:Specimen).
