Can anyone show me an example of how the ReferenceInformation class is used?
What's the difference between an "owner" property and a "referenced" property? For example, what objects do OwnerLanguage and ReferencedLanguage refer to?
An IEnumerable<ReferenceInformation> is returned by the GetReferencesToContent(ContentReference, Boolean) method of IContentRepository.
Can I use it to get from one language version of a page to another version of that page in a different language?
I think both of them will return the same language. If you want to load a different language just use the IContentLoader to reload the ReferencedID in whatever language you need or to load all the languages of a content item
