Data structure

An idea of data structure to be tested:

Accession: information about the accession and its provenance. Location, collecting date, collector, identifications etc.

Branch: events tied to a location in garden: describes what has been done to the parts of an accession. These form a branching structure where the history of each individual plant can be tracked. The 'tails' of the branches show what kinds of descendants of the accession are present in the garden.

Below is an example where a single plant and 10 grams of seeds were collected, and have resulted in 1+7 plants in garden, 8 sown but ungerminated seeds, and some amount of seeds in seed storage.

When only part of one branch is tended, the system automatically splits the branch in two. This is controlled by the inclusive-field. For example: If there is 10 grams of seeds, out of which 15 individual seeds are sown, the user marks this as non-inclusive. Then the system understands that there are still some seeds (10 grams - 15 in this case) in storage, and creates a new branch for the stored seeds automatically (branch ID P6 in the example).
