The data starts out decentralised and disconnected (I am in Australia you are in the USA, working independently) . A third party discovers that she can combine our data and repurpose it. Gray's analysis seems to assume more a priori design than this. i.e. that we can design the system for a specific purpose.

But suppose we create a central site that combines your data with mine and offers a high level api. The economics still depend on how often we change the data and how much upload traffic that creates versus how often people happen to want to use the combined resource under the particular assumptions of the high level api.

Finally, the SW ontology and inference technology is ideal for connecting your independently conceived data with mine whether we do the processing centrally or at each client's site. And REST is a good basis for a high level API....
