Schemata DSL (Schemata Modeling Language, aka SKM)

A Roslyn source generator that compiles .skm schema files into C# entity records, trait interfaces, and enums at build time.

Quick Start

dotnet add package --prerelease Schemata.Modeling.Generator

Add .skm files to your project with Build Action: AdditionalFiles (or use one of the business/module target packages that configure this automatically). The generator runs at compile time and produces C# files in obj/.

What Gets Generated

For each .skm file the generator produces C# source files placed in obj/ and automatically compiled into your assembly:

Entity record — a C# record with all declared fields as properties.
Trait interfaces — a C# interface per Trait block.
Enums — a C# enum per Enum block.

Grammar Overview

Namespace

Every .skm file begins with a namespace declaration:

Namespace My.Project

Traits

Traits are reusable field groups. Entities compose them with Use:

Trait Identifier {
  long id [primary key]
}

Trait Timestamp {
  timestamp? create_time
  timestamp? update_time
}

Trait SoftDelete {
  timestamp? delete_time
  timestamp? purge_time
}

Trait Entity {
  Use Identifier, Timestamp
}

Entities

Entities map to database tables. They generate a C# entity class and one C# record per Object block:

Entity Book {
  Use Entity, SoftDelete

  string title [not null] { Length: 500 }
  string? author
  string? isbn [unique]
  int page_count

  Object detail {
    id
    title
    author
    page_count
    create_time
    update_time
  }

  Object summary {
    id
    title
    author
  }
}

Enums

Enum BookStatus {
  BookStatusUnspecified = 0
  Draft                 = 1
  Published             = 2
  Archived              = 3
}

Field Types

SKM Type	C# Type
`string`	`string`
`text`	`string`
`int` / `integer` / `int32` / `int4`	`int`
`long` / `int64` / `int8`	`long`
`biginteger` / `bigint`	`System.Numerics.BigInteger`
`float` / `float32` / `float4`	`float`
`double` / `float64` / `float8`	`double`
`decimal` / `numeric` / `number`	`decimal`
`boolean` / `bool`	`bool`
`datetime` / `timestamp`	`DateTimeOffset`
`guid` / `uuid`	`Guid`

Append ? for nullable: string? author, timestamp? delete_time.

Field Options

Declared in square brackets after the field name. Multiple options are comma-separated.

Option	Effect
`primary key`	Primary key constraint
`auto increment`	Auto-incrementing primary key
`not null` / `required`	Non-nullable constraint
`unique`	Unique index
`b tree`	B-tree index
`hash`	Hash index

long   id    [primary key]
string email [unique, not null]
string? bio  [b tree]

Field Properties

Declared in curly braces after options. Provide column-level metadata:

Property	Effect
`Length N`	Maximum string length
`Precision N`	Decimal precision
`Default value`	Default column value
`Algorithm name`	Hash algorithm (for hashed fields)

string  title [not null] { Length 500 }
decimal price            { Precision 2 }
