  A conceptual model is a representation of a system.
  It consists of concepts used to help people know,
  understand, or simulate a subject the model represents.
  It is also a set of concepts. In contrast, physical models
  are physical objects, such as a toy model that may be
  assembled and made to work like the object it
  represents. [1]

That simple! ... OK

A physical model can also be a photo model I take it ...

And "meta-information" = metadata ?
