1. A method comprising: defining an object graph comprising a plurality of nodes at a publisher network component connected to a communication fabric, wherein the communication fabric comprises an arrangement of interconnected computing devices; receiving, from a consumer network component connected to the communication fabric, a consumer request for information from the object graph, wherein the consumer request includes an object filter associated with the information that defines which relationships between nodes in the object graph to traverse or not traverse when the information is provided to the consumer network component; accessing one or more policies that indicate which portions of the object graph the consumer network component is allowed to access when the object graph is published based on the object filter; determining, based on the one or more policies, that the consumer request is a request for access that is broader than the access allowed by the one or more policies; filtering, at the publisher network component or within the communication fabric, the object graph using the object filter to generate a filtered portion of the object graph; and restricting publication of the filtered portion of the object graph to include only portions allowed by the one or more policies.
