Labels and prefixes

Various errors on labels. They are visible from the ontology page.

In particular:

• A lot of missing labels, that appear in the summary as mus:U21i_actor_is_subject_of insted as simply U21i actor is subject of
  Among them, there are some in which the label is in rdfs:comment instead of rdfs:label, as in (U217_has_playing_speed)[http://data.doremus.org/ontology/#U217_has_playing_speed]

• Some wrong label, like U217 should have playing speed instead of CLU217 should have playing speed (you can spot them because they have a wrong order in the summary)

• Wrong "code" for CLUP197 should be binding of (CLUP instead of CLU, missing i)
