    1 == Domain data models ==  
     1= A. Domain data models =  
    22 
    33There are at least 5 types of models to be defined. 
    44 
    5 === Substrate description model ===  
     5== Substrate description model == 
    66This is the substrate specific detailed resource and topology model that is used by the substrate manager to describe its physical resource including edge (compute and storage) resource and network topology. It also describes the domain service exposed to the broker.  
    77 '''1. Domain Service Description(domain.owl)'''  
     
    4040         * ethernet.owl,ip4.owl,dtn.own 
    4141 
    42 === Substrate delegation model === 
     42== Substrate delegation model == 
    4343        This is the abstract model that is used by the substrate manager to delegate its available services and resources to outsiders, the clearing house in the GENI context. This mode should allow multiple abstraction levels as different substrate manager may want to expose different levels of resource and topology description of its substrate. The model is obtained online when a substrate is stand up and contains two types of information: 
    4444       * Domain network service. 
     
    5151               * Border interfaces: connectivity to neighboring domains, bandwidth and available label set (e.g. vlan)  
    5252 
    53 === Slice request model === 
     53== Slice request model == 
    5454        This is used by the user, or the slice controller after interpreting the user's requests in ad hoc format, to describe the specifics of the user's request, often this is represented in the form of a virtual topology. This description is sent to the clearing house via '''Request Ticket'''.  
    55         * The topology request is defined a collection of bounded or unbounded connections. The end node of the connection can specify the amount of requested edge resource (e.g. amount of smallSize servers).  
     55        * The topology request is defined a collection of bounded or unbounded connections. The end node of the connection can specify the amount of requested edge resource type (e.g. amount of VMs).  
    5656 
    57 === Slice reservation model ===  
     57== Slice reservation model ==  
    5858        This is used by the clearing house (brokers) to return resource reservation description to the slice controller so that the controller can use to talk to related substrate manager to '''redeem tickets'''. This model should be able to describe the interdependency relationship among the slivers so that the controller can stitch to a slice. 
    5959   
    60 === Slice manifest model === 
     60== Slice manifest model == 
    6161        This is used to describe the access method, state, and other post-configuration information of the reserved slivers. 
    6262 
    63 ==Semantic description of the data models==  
     63= B. Semantic description of the data models =  
    6464We envision NDL-OWL would provide an unified semantic schema for above 5 types of data models, which will be represented in RDF format. We use NDL-OWL - a further development of the [http://www.science.uva.nl/research/sne/ndl Network Description Language], for the [http://ben.renci.org BEN] network resource description, slice requests and slice descriptors. We have extended the original NDL using OWL. We are also in the process of including more technologies into the NDL-OWL [https://geni-orca.renci.org/owl schema]. 
    6565 
    66 ==Service provisioning implementation==  
     66= C. Service provisioning implementation =  
    6767We are trying to stay away from the procedural programming model to a semantic query based programming approach. 
    6868We use a number of [wiki:OrcaNDL tools] to create and manipulate NDL-OWL ontologies.  
    6969 
    70 ==Resource allocation policies== 
     70= D. Resource allocation policies =
