PoE dat schema

Source of truth schema for dat files.

Using

Each commit triggers a CI build that exports schema to JSON. You can always curl latest version at github.com/poe-tool-dev/dat-schema/releases/download/latest/schema.min.json

Structure of JSON file is described in src/types.ts

Schema

The schema is based on GraphQL syntax.

Supported scalar types

Type	Description
bool	Boolean
string	String
i32	Signed Integer
f32	Floating Point Number
rid	Index to a Row in a Foreign Table

The rid type is intended to be used temporarily until we know the name of foreign table.

The other type for temporary use is _, which is only allowed inside array [_]. You will find it useful if you know that a column is an array but don't know of which type (because they are all zero-length).

Defining relations

• Using a row index

  Example BaseItem: BaseItemTypes

• Using a matching value in column (like in relational databases)

  Example SkillId: ActiveSkills @ref(column: "Id")

Supported directives

Directive	Description
@ref(column: String)	Defines a relation
@unique	All values in a column are different
@localized	Content of column differs depending on the language
@file(ext: String)	Value in a column is a file path
@files(ext: [String])	Value in a column is a common prefix for several files (often with different extensions)
@tags(list: [String])	Add tags to the table as metadata that can be used by tools
