DSM: Describe Your Data Model

A declarative language to define types, structures, and relationships. Write once, generate everywhere.

What is DSM?

DSM (Digital Substrate Model) is a declarative language for defining your application's data model. Instead of writing repetitive boilerplate code, you describe what your data looks like, and Kibo generates the how.

Five Fundamental Notions

Namespace

Organize your model into logical modules. Maps directly to C++ namespaces and Python packages.

Concept

The core entity in your model. Like a class, but with built-in persistence, versioning, and serialization.

Key

Unique identifier for concept instances. Type-safe references between entities.

Document

Standalone data structures. Perfect for configuration, metadata, or transient data.

Attachment

Properties of concepts. Strongly typed with support for primitives, containers, and references.

Type System

DSM includes a complete type system:

Primitives: bool, int8-64, uint8-64, float, double, string, blob
Containers: vector, set, map, optional
Structures: struct, tuple, enum
References: key<Concept> for type-safe foreign keys

Quick Example

namespace Graph {27c49329-...} {

concept Vertex;
concept Edge;

struct Position {
    float x;
    float y;
};

attachment<Vertex, Position> position;

};
