Fist, the examples:

• Show all photos in collection (no restraints; click on links for thumbnails)
• Show all photos of Hoesch Stahl facilities (one restraints: operator)
• Show all photos of DSK Deutsche Steinkohle facilities that have been torn down (two restraint: operator, current status)
• Show all photos of facilities that had been in service when visited and are now torn down (two restraints: status when taken photos of, current status)
• Show all photos of coal industry in the city of Bergkamen that had been out of service when visited and is now torn down (four restraints: industry, city, status when taken photos of, current status)

So what's this?

This is about applying the idea of faceted navigation to tagging. If you have a look at my del.icio.us links, you will find tags consisting of a prefix, a colon and a suffix like is:quicklink, project:ilm or via:papascott. Buzzword: structured tagging. Rainer Wasserfuhr is playing with similar things. Now let's build facet:topic-style tags: a facet is a perspective from which to look at a data pool or a characteristic of an item, e.g. company, kind of industry, location or site name, a topic a facet's value like Berlin, Hamburg or Munich (location-facet). Now let's query for intersections of tags describing different facets, and voila: the power of faceted navigation combined with the freedom of a tagging. Buzzword: semantic tagging. Above is a simple proof of concept in del.icio.us. I will use this kind of faceted navigation in my photobase. In a later posting: tool requirements and vocabulary issues.
