Media type name: application

Media subtype name: vnd.dgl

Required parameters: N/A

Optional parameters: N/A

Encoding considerations: binary

Security considerations: This media type contains executable machine code designed to function as a dynamic library for game engines. Since it executes binary code directly on the host processor, it carries risks associated with arbitrary code execution if modified by malicious actors. Security relies heavily on the host operating system's native dynamic linking security mechanisms. Applications using this format are advised to implement digital signature verification and checksum validation before loading the library into memory to ensure data integrity and prevent unauthorized code injection.

Interoperability considerations: The .dgl format is designed to be cross-platform, but actual compilation depends on the targeted operating system architecture (e.g., PE format for Windows, ELF format for Linux). Care must be taken by developers to compile for the specific target architecture of the host game engine.

Published specification: None. The specification is currently private and under development by the vendor.

Applications which use this media: Custom game engines, game runtime environments, and integrated development environments (IDEs) designed for modular game architecture.

Fragment identifier considerations: None. Fragment identifiers are not applicable to this binary format.

Restrictions on usage: None.

Additional information:

1. Deprecated alias names for this type: N/A
2. Magic number(s): None. Follows standard PE/ELF binary headers.
3. File extension(s): .dgl
4. Macintosh file type code: None.
5. Object Identifiers: None.

General Comments: This registration is for establishing a formal media type for modular dynamic game libraries used in independent game development. This file extension enables games to manage in-game settings, graphics, and more using these libraries.
