6 Synthetic Environment Common and shared representation of the background field Eliminate duplication of the most common objects that are often the least dynamic 6

7 Models Structural building blocks for functionality Object taxonomy for identity and relationships These are the hardest and least advanced 7

8 User Interfaces Data Creation building and editing the virtual world Data Presentation performance analysis System Controls operating the system 8

9 Translators Every device speaks a different language There is always a need for translation of bits, words, packets, and forms Standards for Interoperability can significantly reduce, but never eliminate this need ABGABCEBEBABCG ΛΓΦϑΠΨΟςΩΙΜΨ 9

10 Standards in System Interoperability Common Model Ontology Shared Model Proxy Network Services Network Protocol Enumerations 10

11 Common Model Ontology A formal representation of knowledge as a set of concepts within a domain, and the relationships between those concepts. Used to reason about the entities within that domain. Required to allow models to interact with each other. What are you? How are you related? What can I do to you? 11

12 Shared Model Proxy A representation that is a minimal, but essential substitute for the modeled object. Provides a least-common-denominator of state values that can be universally agreed upon. Who am I? 1) ~~~~~~ 2) ~~~~~~ 3) ~~~~~~ 4) ~~~~~~ 5) ~~~~~~ Who am I? 1) ~~~~~~ 2) ~~~~~~ Who am I? 1) ~~~~~~ 2) ~~~~~~ Who am I? 1) ~~~~~~ 2) ~~~~~~ 3) ~~~~~~ 4) ~~~~~~ 5) ~~~~~~ 6) ~~~~~~ 12

13 Network Services Provided by a common software library that will perform actions in the same manner for everyone. Reduces duplicate software and duplicate errors. Increases standardization of actions, processes, and protocols Press 1 to send greetings Press 2 to send a bomb Press 3 to intercept calls Press 4 to jam all radios 13

14 Network Protocol Simulation state information is encoded in formatted messages and exchanged between computers and simulation systems. One popular protocol (DIS 6) defines 67 different message types (PDUs), arranged into 12 families.

15 Enumerations An exact listing of all of the elements in the set. These compactly encode data that needs to be understood by different computer programs. Ground Vehicle = 100 Tank = 101 Truck = 102 Robot = 103 Air Vehicle = 200 Fighter = 201 Tanker = 202 Cargo = 203 Naval Vehicle = 300 Carrier = 301 Battleship = 302 Terrain = 400 -River = 401 -Tree = 402 -Bridge = 403 -Building =

16 Medical / Military Collaboration on Standards Are both communities prepared to collaborate? Are they able to persist long enough to bridge differences in vocabulary, history, customer needs, funding, etc?
