Overview

• Introduction• Capabilities• Enhancements and Fixes• SORD Gateway Efforts• Client Capabilities• New Applications of the SGW

Introduction

The SORD Gateway is a component in OneSAF that provides HTTP access to OneSAF’s distributed runtime simulation data.

• Uses standard mechanisms for data distribution• HTTP for database queries• XML used to encode objects

• REST principles with HTTP request verbs• Provides a non-simulation specific API that improves

scalability• Objects and interactions in the SORD are resources for

clients to act on via the SORD Gateway

Simulation Needs

Simulation community needs addressed by the SORD Gateway:

• Reusable components• Enhanced methods of interoperability• Solutions for complex, larger training

problems• Rapid prototype results• Support multiple communication protocols,

fidelities, and configurations

Capabilities

The core capabilities of the SORD Gateway are• Getting, deleting, creating, and updating

objects • Subscribing to object and interaction events• Creating and firing interactions• Defining new object and interaction types

Enhancements - Dynamic Requests

• Requests provided by SGW are its resources• SORD has different resources (objects, interactions)

• Requests extension framework• uses OneSAF composability concepts• Allows now we can add specific capabilities without

cluttering core functionality• Advantages• Keep SGW generic and simulation independent• Minimize OneSAF dependencies and changes

Enhancements - Online Help

• Help is provided online while SORD Gateway is running• Web browser accessible

• Content is accumulated from all available SGW request resources

• Manually exported for offline viewing in our documentation folders

Enhancements - Other

• JUnit tests• Multi-client notification/subscription support• Performance • Tests written• HTTP Compression

SORD Gateway Efforts

Several projects within the RDECOM-STTC use the SORD Gateway for their research efforts.

Each project demonstrates a new requirement for interoperability to satisfy a complex training requirement.

SORD Gateway Efforts

• Game Based C2• SGW used to inject externally calculated physics

effects into OneSAF• ARA SGW Client and RPEL

• Rubble• SGW used to create rubble piles based on external

calculations for flyout debris• Anyar, Inc. physics motion solver• ARA SGW Client and RPEL

SORD Gateway Efforts

• HI2NT• SGW used to assist in transferring combat

intelligence information into OneSAF• ARA SGW Client• MATREX ProtoCore API

Client Capabilities

These are documented efforts on how the SORD Gateway was used to accomplish certain goals. They may or may not require code changes.

• How-to information written up• Minimal to no code changes needed• Proof-of-concept tests

Client Capabilities

• Ownship• Client goal: override entity location (mobility) and

damage state (vulnerability)• Documented how to use existing framework

within OneSAF• Mood/Gesture• Communicate mood/gesture from JNEM to

OneSAF• OneSAF RDM modified to store values per entity

Client Capabilities

• Creating Rubble• Inject rubble piles into OneSAF during scenario

run based on external physics calculations• Proof-of-concept test uses existing OneSAF

dynamic terrain with minor workarounds• Scenario Management• Change simulation state via the SORD Gateway• JUnit test and SORD Gateway dynamic request

created

New Applications of the SORD Gateway

In what interesting ways can we enhance the SGW or use existing enhancements to further promote interoperability to solve complex use cases?

• Graphical User Interfaces• Object Wrappers

Graphical User Interfaces

The SORD Gateway publishes available client requests via URL.

• Content is available as HTML or XML• Publication is dynamic based on runtime

settings• Originally started as a means of capability

testing

Graphical User Interfaces

When available requests are retrieved as HTML content ...

• A web form is provided for user interaction • viewable within an internet browser• requests can be made via ‘point and click’

• Allows for independent user interfaces via web enabled desktop applications

Graphical User Interfaces

When available requests are retrieved as XML content ...

• Same scalability, more powerful• Not limited to Gateway’s HTML rendering• Clients can render content into HTML or other

GUIs to create custom applications

Object Wrappers

The SORD Gateway allows you define new data types at runtime for information storage and distribution.

• Data changes only remain while running after being defined• minimal effort to setup and/or change• no hard coded changes required

Object Wrappers

• Extend OneSAF data for data tracking and linking in federate/client• Wrap existing OneSAF objects to add metadata

about that object that is not represented

Object Wrappers

• Disguise OneSAF data for different visual representation within federate/client• Wrap existing OneSAF objects to represent them

differently than they really are
