    99== 1. Substrate description model == 
    10 This is the detailed resource and topology model that is used by the owner of the substrate to describe its physical resources including edge (compute and storage) resource and network topology.  ORCA AMs use this representation to delegate advertised resources to ORCA broker(s).  AMs may also use this representation to describe resources in response to queries (e.g., ListResources) or to advertise resources to a GENI clearinghouse.  
     10This is the detailed resource and topology model that is used by the owner of the substrate to describe its physical resources including edge (compute and storage) resource and network topology.  ORCA AMs use this model to drive their internal resource allocation policies and resource configuration (setup/teardown handler invocations).  The model also specifies which elements of the structure are exposed externally (e.g., in resource advertisements or delegations), and which are kept hidden.

    12       The class hierarchy is defined in the diagram below. A substrate (domain) is defined as a collection of !PoPs. Each PoP has a geographical location and a collection of network devices and/or edge resources (e.g., a cloud provider site). The Class ''Domain'' also has a property ''!NetworkService'' which could have a number of ''!ServiceElement''. This information would be passed to the advertisement RDF.

    1313             * !AccessMethod: e.g. ORCAActor, or GENI AM API. 
    1414             * Topology: Topology abstraction level exposed to outside. Right now, only node abstraction is defined.

    7373== 2. Substrate delegation model == 
    74         This is the abstract model that is used by the substrate manager (AM) to delegate its available services and resources to external brokers, e.g., a GENI clearinghouse. This mode should allow multiple abstraction levels, as different AM may want to expose different levels of resource and topology description of its substrate. The model is obtained online when a substrate stands up; ideally this can be automated.  The model contains two types of information:

    7575       * Domain network service. 
    7676             * !AccessMethod: e.g. ORCAActor, or GENI AM API.
