Indeed not all fields apply to all files/categories. Those that apply to every
file should be linked to a generic File category.
Hardly audio.composer applies to a text document, and if assigned doesn't
really make sense. Such limitations are natural, not artifical. They just
expose semantics better. To human, composer as such applies to music, but
software can only understand this link if directly specified. For interop
with other software, it's better to have explicit field-category links.
Current implementations can ignore this and rely on data extraction code to do
