  With the recent advances made by Cherenkov telescopes such as H.E.S.S., the
field of very high-energy (VHE) gamma-ray astronomy has recently entered a new
era in which for the first time populations of Galactic sources such as e.g.
Pulsar wind nebulae (PWNe) or Supernova remnants (SNRs) can be studied.
However, while some of the new sources can be associated by positional
coincidence as well as by consistent multi-wavelength data to a known
counterpart at other wavelengths, most of the sources remain not finally
identified. In the following, the population of Galactic H.E.S.S. sources will
be used to demonstrate the status of the identifications, to classify them into
categories according to this status and to point out outstanding problems.
