Good morning Sridhar,
To clarify, I think it would have been simpler to define amg:dc.
I also noticed as per Renato’s comment, but focused on your original question.
If you’re satisfied with your definition, I suppose we have no further comment around it at this stage.
Regards,

Respected Sir,
Forgive me for my persistence with a presumption that I may be wrong.
I was just trying to use a custom dataType amg:dc to set the type
of the IRI <http://www.amagi.com/metadata/ontologies/media/dc#_VOD>.
Please see

Sridhar,
Renato refers to this 2 lines:
odrl:rightOperand <http://www.amagi.com/metadata/ontologies/media/dc#_VOD> ;
odrl:dataType amg:dc ;
Where <http://www.amagi.com/metadata/ontologies/media/dc#_VOD> is a URI, could be from the xsd namespace you already imported:
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
odrl:rightOperand <http://www.amagi.com/metadata/ontologies/media/dc#_VOD> ;
odrl:dataType xsd:anyURI ;

Sir, in the current context i wanted to qualify the type of the rightOperand instance as done in
EBU classification schemes in SKOS. As in https://www.ebu.ch/metadata/ontologies/skos/ebu_Iso3166_CountryCodeCS.rdf
specified in https://www.ebu.ch/metadata/ontologies/skos/?_gl=1*xqztea*_ga*MTkxNTUyMjk1Ni4xNzEwNzY5ODY5*_ga_TVTB816MPW*MTcxMDc2OTg2OS4xLjEuMTcxMDc3MDE4Mi42MC4wLjA.

Hi Sridhar…a small point...
The odrl:dataType is the data type of the value of odrl:rightOperand.
In the example below, that does not seem correct as the value of odrl:rigthOperand is a “URI” datatype.
Cheers - Renato

I tried to model (forgive my naivety) by addressing both of these cases through a single leftOperand ('deliveryChannel') and by specifying different 'types' of the rightOperand values through odrl:datatype (amg:dc for VOD and amg:lc for linear channels).
The modelling was to be as follows:
Example (a) :
<http://example.com/policy:1010>
a odrl:Set ;
odrl:permission [
odrl:action odrl:play ;
odrl:target <http://example.com/asset:99898> ;
odrl:constraint [
odrl:leftOperand odrl:deliveryChannel ;
odrl:operator odrl:eq ;
odrl:rightOperand <http://www.amagi.com/metadata/ontologies/media/dc#_VOD> ;
odrl:dataType amg:dc ;
];
