# ACSets Hatchery
## Overview
**ACSets.jl** provides acsets ("attributed C-sets") - data structures generalizing both graphs and data frames. They are an efficient in-memory implementation of category-theoretic relational databases.
## Core Features
- **Acset schemas** - Category-theoretic data structure definitions
- **Acsets** - Instances of schemas (like database rows)
- **Tabular columns** - Efficient columnar storage
- **Serialization** - JSON/binary format support
## What Are ACSets?
An ACSet is a functor from a category C to Set, with attributes. This means:
- **Objects** become tables
- **Morphisms** become foreign keys
- **Attributes** add data types to objects
## Usage
```julia
using ACSets
# Define a schema
@present SchGraph(FreeSchema) begin
V::Ob
E::Ob
src::Hom(E, V)
tgt::Hom(E, V)
end
# Create an acset
g = @acset Graph begin
V = 3
E = 2
src = [1, 2]
tgt = [2, 3]
end
```
## Extensions
- **Catlab.jl** - Homomorphisms, limits/colimits, functorial data migration
- **AlgebraicRewriting.jl** - DPO/SPO/SqPO rewriting for acsets

# Rec2020 wide gamut with acset seed
gay_seed!(0xb4545686b9115a09)
# Mixed mode checkpointing
params = OkhslParameters()
