Dear Wonsuk,


While looking at the MA ontology examples, I recognized some issues in your
youtube [1] example:

The value of ma:hasCompression is a string. Since ma:hasCompression is an
ObjectProperty, a literal cannot be its value, instead a resource is

compression as label.

Furthermore, ma:format is not part of the MA spec and should be changed to


Can you please address these issues?!
