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
i16, i32	Signed Integer
u16, u32	Unsigned 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
