[Karen Coyle]

谢谢你，菲尔，我纠正你。我没有考虑schema的“domainIncludes”。“domainIncludes”的使用允许schema.org以这种方式非常灵活:Rdfs:标记“actor”;schema:domainIncludes schema:Clip, schema:Episode, schema:Movie, schema:MovieSeries, schema:RadioSeries, schema:TVSeries, schema:VideoGame, schema: videoameseries, schema:VideoObject;schema:rangeIncludes schema:Person;schema:supersededBy schema:actor;rdfs:评论“一个演员，例如在电视，广播，电影，视频游戏等。演员可以与单个项目联系在一起，也可以与一个系列、一集或剪辑联系在一起。”． While multiple domains are allowed by RDFs, I'm assuming that schema's domainIncludes is designed to get around the definition in RDFs: "Where a property P has more than one rdfs:domain property, then the resources denoted by subjects of triples with predicate P are *instances of all the classes* stated by the rdfs:domain properties." [1] By using domainIncludes one is not supporting an inference that the subject of a schema.org statement with the property schema:actors is at all times a member of all of these classes. (Which wouldn't be sensible, as it is hard to imagine how something could be a VideoGame AND a Episode AND a TVSeries AND a RadioSeries.) In fact, domainIncludes seems to be a kind of RDF profiling method, creating a shape with properties. Hmmmmm. I admit that I am not sure how these schema.org "domains" fit into the RDF world. I need to think more about that. However, presumably folks creating schema.org data will use "rdf:type" in their instance data to define the class of the subject, not relying on inferencing from the schema vocabulary. We'll pick up on this use case in the future.
