# Resource Library

The PLR Resource Library (PLR-RL) is the world's biggest and most accurate centralized collection of labware. If you cannot find something, please contribute what you are looking for!

## `Resource` subclasses

In PLR every physical object is a subclass of the `Resource` superclass (except for `Tip`).
Each subclass adds unique methods or attributes to represent its unique physical specifications and behavior.

Some standard `Resource` subclasses in the inheritance tree are:

```
Resource
├── Carrier
│   ├── TipCarrier
│   ├── PlateCarrier
│   ├── MFXCarrier
│   ├── ShakerCarrier
│   └── TubeCarrier
├── Container
│   ├── Well
│   ├── PetriDish
│   ├── Tube
│   └── Trough
├── ItemizedResource
│   ├── Plate
│   ├── TipRack
│   └── TubeRack
├── Lid
├── PlateAdapter
└── MFXModule
```

See more detailed documentatino below (WIP).

### Plate Naming Standard

PLR is not actively enforcing a specific plate naming standard but recommends the following:

<img src="_ims/PLR_plate_naming_standards.png" alt="PLR_plate_naming_standards" width="500"/>

This standard is similar to the [Opentrons API labware naming standard](https://ecatalog.corning.com/life-sciences/b2b/UK/en/Microplates/Assay-Microplates/96-Well-Microplates/Costar%C2%AE-Multiple-Well-Cell-Culture-Plates/p/3516) but 1) further sub-categorizes "wellplates" to facilitate communication with day-to-day users, and 2) adds information about the well-bottom geometry.
