Is there documentation describing a coupling between fields for MRN_STORY and the older News Feed Direct?
For instance, we used to get TopicCodes and for MRN_STORY we now get "subjects" which seem to be the same but which are slightly different. Similarly, we used to get ProductCode which looks strikingly similar to "audiences" coming from MRN_STORY, but they're not exactly the same for otherwise the same article.
Thanks
