The Reference.mdl, conventionally named <modelname>.mdl, contains a range of key information for an in game model:

The model's Origin, which is used to align its rendermesh (VTX), collisionmodel (PHY), gibs, etc to the Model Entity's position in the World.
The names of any sound WAV files used by this model.
The names of the VMT files to use as Skins. (or is this in VTX / VVD files ?)
The name of the PHY file to use as a collisionmodel.
The names of the MDL files used to store animations.
etc

The reference.smd, conventionally named "<modelname>_ref.smd" or "lod0_<modelname>_ref.smd", contains:

The nodes block defines the skeletal Bone Hierarchy.
The skeleton block defines the bone coordinates for a single "idle" animation frame.
The triangles block defines each (triangular) polygon of the (default LOD) Render Mesh.
- Each triangle specifies the default Skin filename, followed by a set of XYZUV coordinates for each of its vertices.
- XYZ are the 3D Mesh coords, and UV are the 2D Texturemap coords.
