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 expected. Therefore I propose to insert a blank node with the value of compression as label. Furthermore, ma:format is not part of the MA spec and should be changed to ma:hasFormat. Can you please address these issues?!
