My experience in companies is that data exchange, data reuse and data referential are a nightmare. My mental model of a company is an insane amount of customized ETL, on top of web services, obscure IDs in each data/service silo representing the same thing, data exchange format poorly (un:)documented that require massive boilerplate code. I think it is the middle age. I have been a huge fan of the LinkedOpenData. And its Lack of adoption profoundly disturbs me. I still don't understand how people can use the Knowledge graph of Google daily, and discard the need for something similar in companies, or widely available for OpenData.
