I am engineer and specialized in nuclear power plants safety. My main hobby is the collection of classic stamps, especially from the "Deutsches Reich" and the KK Austria-Hungary monarchy, with emphasis on the origin of the cancellations. I have developped databases for this purpose. 13 May 2012 - 20 Oct 2013

My grandfather was a landscape painter, and this reflects in the way I compose pictures.

I am autopatrolled since 1 November 2012.

I have studied the concept of thesaurus in order to manage documentation softwares. Hence my interest in the categories and links between them. I try to apply those concepts in the Wikimedia art media, architecture categories. I work a lot in identifying more precise, defined categories. For example, many do not distinguish between door, gate, doorway, portal.. normal, if those words are not defined!

Another issue is the reluctance of some to accept that parent categories are not needed once more specific ones are created, with very strong links (like for locations).

I have a problem with the invasive category ;; by city: undefined (should be by location), biased (all available views are rarely repeated under this cat), redundant (location is already stated in basic cat), in violation with the needed hierarchy by location, etc (2016).

I fully share the beliefs of User: Herzi Pinki, slightly adapted hereafter:

  • Love your photos
  • Categorization is added value
  • Photos should be inspired by nature and culture and beauty
  • Do the selection of images at home and upload only the very few images selected
  • There is no good reason to upload an average image of yours or from some suitable source, if there is already a lot of similar images on the same topic. This holds even more for low quality images.
  • Do not use categories for the obvious, but search the most specific properties only

.. from my experience:

  • Refrain from overcategorization: does the new cat have an encyclopedic interest (postmarks by date ...)? Do I not recreate a parallel structure (Stamps versus Postage stamps; Paintings versus Oil paintings; Women versus Females; Statues versus Sculptures etc..)?
