Interoperation is difficult

Multiple standards (HLA, DIS, etc)
Dozens of implementations
Hundreds of models, workflows, and systems
Sources of complexity
Distributed systems
Parallel computation
Heterogeneous run-time infrastructure
Mixed platforms and use cases
Many more!

Simplifying interoperability: GeoDispatch

Goals

1. Simple, platform/language independent interface
RESTful web service
2. Standard and well supported protocols, serializations,

data types

HTTP, JSON, ESRI ArcGIS
3. Maintain asset and metadata states

GeoDispatch: System architecture

Server
Transactional REST web service with two

“endpoints” (GET, POST, DELETE)

…/rest/tracklogs: Maintain asset location and state
…/rest/graphics: Maintain metadata location and state
Client
Implement a REST layer
Transcode tracked assets into standard data
Transcode geospatial cues and metadata

Conclusions Key takeaways

Lightweight synchronization services work well for interoperability.
Standard and well-supported protocols, schemas, and data types greatly

simplifies the integration process.

Particularly across platforms and languages
