MDD

MDD is a Metadata definition file format used to describe Metadata information about digital media content. MDD files contain object names, properties, relationships, and other related information that can be used by applications or systems to manage and process digital media content. The MDD format is commonly used to store model and animation data and is often used in game development. It can describe information such as geometry, texture, lighting, and animation of 3D models so that game engines can load and render this content quickly.
