You say it much better than I.

The copyright field is unformatted text, but we'll recommend a specific 
format from which license and license claim urls can be extracted. 
Excerpted from <http://creativecommons.org:8000/learn/technology/mp3>:

   TCOP (Copyright Text) should include a human-readable license and
   license claim information. The contents of this frame are displayed
   by many programs in a "file info" window. Example value: 1995 Example
   Band. Licensed to the public under
   http://creativecommons.org/licenses/by/1.0/ verify at

   If "verify at " exists in TCOP, everything after it must be the
   license claim URL, and if there is a license claim URL then it must
   be preceded by "verify at ".

For MIDI the instructions would be the same, just replace "TCOP" with 
"copyright event".
