Are Tags the Answer?
A Thing has many 'names' – they are all attributes or tags
Notes:
Points to note here:
Sometimes attributes contain further data
That data may be free-from or, in the case of things like dates it may have a set format.
Sometimes there is an overlap between the data content of the attribute and other attributes: Is 'Orchid' an attribute of the photo or is the the data that is associated with the Subject?
