Domain Model: Plant Batches

[jhanarato]

We have data for most of the native plants supplied to us. This information is part of our domain model. How does this work?

• We receive grants for projects.
• For some projects we are supplied with native plants.
• For others we are given money and purchase the plants ourselves.
• When provided with plants, we sometimes receive a list in advance.
• When we buy plants ourselves we place an order.
• When provided with plants we take stock of what has been received.

Our current way of storing information is in a folder on my desktop. This includes PDFs, Excel and LibreOffice files and scans of written information. For example:

Trillion Trees Quote - 11th May 2020

• Bought from Trillion Trees in Guildford. This organisation used to be called Men of the Trees.
• Picked up by J.R.
• Several species, each with a description (e.g. Banksia littoralis), quantity, unit price, amount per species.
• Total price of order.

Plants from Mon's Group - 6th September 2021

• Bought for us by lay supporters
• Species name in Latin
• Quantity
• Notes with English name and preferred soil.

This is a good starting point for our model.

We can have two kinds of batches:

• Received batch: it's arrived and catalogued.
• Ordered batch: we've specified the stock we want.

This typically happens with Habitat Links. There's variation that could be captured with a "compare batches" service. Return a list each of missing stock and extra stock.
