Novel tools and techniques are provided for implementing model driven service state machine linkage functionality amongst different machines and/or networks. In some embodiments, a computing system of a first network associated with a first entity might establish a communication link with a node of a second network associated with a second entity. The computing system might determine whether there is a common network resource state schema between the two networks, and, if so, might identify available versions, then negotiate which version to use as common version. The computing system might retrieve network state information for the two networks, might generate a user interface that incorporates and presents the network state information for the two disparate networks consistent with the common version of the common schema, and might send the user interface to a user device of a user for display of the network state information of the two disparate networks.
