p.s. - oh screw it, has anyone tried classifying music
pre-existing '8' categories (now over 200 and still not a free-format
list) that were provided by some music players 20-30 years ago and
really thought that just one category applied to their music? Is
software that different?
That's an interesting direction to look in: what other classifications
are out there and how well do they work? I think art is always a bit
hard to classify, although art historians try to put it into boxes as
much as possible.
But scientific papers are actually classified by systems very similar to
rpm Group tags:
* the Mathematics Subject Classification (MSC) ,
* the Physics and Astronomy Classification Scheme (PACS), discontinued
but apparently still used ,
* the classification of papers in arXiv .
These are all hierarchical, and either allow just one classification, or
have a primary classification.
These classifications are probably not always perfect, and just like
with Group tags it might happen that no group matches exactly, or
multiple groups apply. Yet judging from their usage the benefits seem to
outweigh the costs.
