Material sample without catalogued object? #28

Open cgendreau opened 4 years ago

cgendreau commented 4 years ago

From @jmacklin : I think there are use cases for a material sample to exist without being catalogued for example a bulk trap sample in Entomology that is unprocessed. This sample would have a collecting event and need to be discoverable (has a preparation and a storage location). Thus, material sample will need an ID that allows a barcode to be made for the “container” the bugs are in so it can be stored and found. Otherwise, a material sample always is a catalogued object with a preparation and storage location, etc…?

In that case I would say yes, there is 1 catalogued object representing the entire material sample. The only use case I could think is if we have the material sample but the preparation is not done yet. But, in that case we should simply not create the MaterialSample and leave it at Collecting Event.

Proposed change: MaterialSample 1 ----- 1..* CataloguedObject

This is described in physical entity and catalogued objects So, issue can be closed, if you agree.

The answer to this really depends on how Catalogued Objects are conceptualized. In my opinion it is the case that there are material samples of interest (i.e. we'd like to record information about them) without a relation to a collection object which is the concept nearest to catalogued object that makes sense to me.

From my current understanding, catalogued objects are physical entities that have been assigned an identifier and other metadata indicating they are catalogued. Is it this simple?

That's the point I was making all along in the discussion. So from my point of view: yes, it is that simple.
