We need business models which support partially-open graphs, e.g. object IDs and some metadata are open, some metadata is closed via API. Open metadata can be cached offline and standardizes models within a vertical market, driving demand for paid metadata. API revenue grows as the open graph grows.
Semi-open knowledge graphs reduce the cost of adversarial algorithms. Better to have many competing skynets than one big skynet. The open part of the graph lowers the cost of consumption. Multiple, closed annotations on the graph compete to support AI use cases, and can optionally become open as value moves to higher-order representations.
