What is the best tagging approach when you have to tag distinct entities that are identified by the same name?
For instance, if I am tagging pictures of railway stations with hierarchical keywords, I will have something like this:
London
Cannon Street station
because the station has a unique name.
But in this other case is it better to use this
Witham
railway station
or this
Witham
Witham railway station
?
Considering this last example, I suppose that the one of the main differences is that if you use the first tag couple maybe you can do more effective searches for railway stations within your catalogue. While if you use the second example you can search for a certain item (in this case the Withem railway station) without using combinations of tags.
