RE: Issues in youtube ontology example

Hi. Martin.

Thanks a lot for good comments.

For the ma:hasCompression and ma:hasFormat, I will revise the youtube
ontology example as below.

 

<ma:hasCompression rdf:parseType="Resource">

<rdfs:label
rdf:datatype="http://www.w3.org/2001/XMLSchema#string">application/x-shockwa
ve-flash</rdfs:label>

</ma:hasCompression>

 

 

<ma:hasFormat rdf:parseType="Resource">

<rdfs:label> application/x-shockwave-flash</rdfs:label>

</ma:hasFormat>

 

In addition, your comments are also valuable to other examples I take care
such as MediaRSS [1] and TXF [2] examples.

Therefore, if you are ok for upper proposal, I will apply these style to
three examples.

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?!
