Yes, exactly. However, there are many possible layouts, it's not completely trivial:
http://www.geomview.org/docs/html/OFF.html

Many webpages mention only the most common layout which is very rudimentary with only 3D vertices and faces with colors without normals and without texture coordinates. Some programs generate files that violate a little bit the specification by writing the off keyword on the same line that the number of vertices. I have found no example of color map, which is stored in a separate file named cmap.fmap. The data can be arranged in several orders depending on the off keyword.
