    57We use a set of unified semantic schemas (ontologies) for representing the data models to describe resources in a reservation across the stages of its life cycle. We develop NDL-OWL - an extension of the [http://www.science.uva.nl/research/sne/ndl Network Description Language] using OWL.  We use a number of [wiki:OrcaNDL tools] to create and manipulate NDL-OWL ontologies. NDL-OWL gives us a flexible semantic query-based programming approach to implement the policies for resource allocation, path computation, and topology embedding.  It enables these functions to be coded generically to operate on declarative specifications, rather than baking in assumptions about the resources.

    7 There are at least 5 types of models to be defined.  ORCA actors (authority/AM, broker and slice manager/SM) pass these representations as they interact to stand up reservations at multiple substrate aggregates and stitch them into an end-to-end slice. 
     9There are at least 5 types of models to be defined: 
     10 
     11 * Substrate description (what an AM knows it has) 
     12 * Substrate delegation (what an AM delegates to a particular broker) 
     13 * Slice request (what a user requests) 
     14 * Slice reservation (returned by a broker) 
     15 * Slice manifest (returned to the user)
