Repository files navigation


This repository has up to date column/field definitions for database files used in World of Warcraft.


  • Updated definitions for all World of Warcraft builds between and current
  • New builds added soon after release (as long as there are no major DBC format changes)
  • Human readable
  • Machine readable (C# and Python code available as well as a tool to convert DBD to JSON/XML)

Project goals:

  • Updated database definitions for all versions of World of Warcraft (work ongoing, some already available)

Cool stuff we might end up doing if this gets enough traction:

  • Repository will feed automated updates on
  • More? Open an issue if you have any ideas


A manifest.json file exists in the root directory as a list of known DBC/DB2s.

Note: This file currently only lists DB2s available in modern builds, it will be backfilled with older data in the future.

Possible keys per entry:

  • tableHash (required) Table hash of the table name
  • tableName (optional) Table name, this can be placeholder if name is unknown and as such can change. Should always match .dbd filename.
  • db2FileDataID (optional) FileDataID of the .db2 file
  • dbcFileDataID (optional) FileDataID of the .dbc file

DBD Format

If you have any suggestions for changes or additions to the format, feel free to open an issue. The DBD format is currently specified as follows:

Column definitions

List of column definitions at the start of the file. This is defined once per column at the start to help keep column names the same across the file.

Starts with COLUMNS, followed by the following:

Regular: type ColName

Foreign keys: type<ForeignDB::ForeignCol> ColName

Localized strings: locstring ColName (see this and this page on Wiki, same as "string" type as of 4.0+ but still localized in locale specific files)

You can also add a comment to a column definition by adding // Comment goes here at the end of the line.

Valid types that parsers should support: int/string/float/locstring

Unverified columns (guessed, etc) have a ? at the end of ColName.

Version definitions

BUILD is required. LAYOUT is required for versions that have it. Can be both.


Line starts with LAYOUT followed by a list of layouthashes separated by a comma and a space. Can appear only once.


Line starts with BUILD followed by a range, multiple exact builds separated by a comma and a space or a single exact build. Can appear multiple times.


Line starts with COMMENT, only for humans. Can appear only once.



Ranges for current expansions should be specified per minor version to not conflict with other branches. Example:


As no more builds/branch conflicts are expected for anything older than the current expansion, ranges are allowed to span a full expansion. Example:


When using ranges, please confirm that the range is correct by verifying the version definition for all public builds included in it.

Multiple exact builds


Single exact build



ColName refers to exactly the same name as specified in the column definitions.

No size (floats, (loc)strings, non-inline IDs): ColName

Size (8, 16, 32 or 64, prefixed by u if unsigned int): ColName<Size>

Array: ColName[Length]

Both: ColName<Size>[Length]

With comment (for humans): ColName // This is a comment, yo!

Column annotations

ColName can be prefixed with annotations to indicate that this is a special kind of column in this version.

Annotations start with a $ and end with a $ and are comma separated when there's more than one. Current annotations:

id this column is a primary key. Example: (inline) $id$ColName (non-inline) $noninline,id$

relation this column is a relationship. Has noninline when stored in relationship table. Examples: (inline) $relation$ColName (non-inline) $noninline,relation$

noninline this column is non-inline (currently only used for $id$ and $relation$). See non-inline examples above.

File handling

Files will be saved with DBName.dbd filenames where DBName is the exact name of the DBC/DB2. Every file has multiple definitions for each different structure that has been encountered for that file. Version structures are separated by an empty new line. All line endings should be in Unix format (\n).
