Re: is overloading of leftOperand possible using dataType pertaining to rightOperand ?

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 ; 

 

Regards,

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 ;

        ];

    ];

    .
