ThingInterface does not have contentUrl

[aggelosgkiokas]

In the modelling discussion, for AudioObject, MediaObject and VideoObject, the URI of the object is contained in the contentURL feld.

However, for requesting a ControlAction, it is impossible to access this field, because the the PropertyValue nodes do not support this.

PropertyValue --> NodeValue implements ThingInterface. ThingInterface does not have contentURL field.

Could be a solution to just add the contentUrl field in ThingInterface??

Unfortunately we can't put contentUrl in ThingInterface, because it means that all objects that implement ThingInterface would have to add it, and that doesn't make sense.

Can you perform a query like this?

nodeValue {
    identifier
    ... on AudioObject {
        contentUrl
    }
}
