What Does a Semantic Interoperability Architecture
Look Like?• This Pilot is a Practical Example
Emergency Management Centered Participants Represent Spectrum of
Related Services• Participants Partner through
Semantically Searchable Registries using Web Services
• Messaging Flows show Architecture• Most Participants' Services are
Geospatially Indexed by Geopolitical Address and/or Geospatial Coordinate Reference System (CRS) for Physical Area

Geospatial Keys to Improving Rapid First Response
• 2 Geographic Data Contexts Support DRM: Geopolitical Standards: Addresses: Town,
County, State: Graniteville, Aiken County, South Carolina
Geospatial Standards: Coordinate Reference Systems (CRS): Lat/Long can be Converted to Each Other
Both Contexts have Multiple Standards: Local, Regional, National, ISO, ANSI, etc

Geospatial Keys to Improving Rapid First Response
• Many Geospatial Concepts Support DRM: ISO 19115 Defines "Extent": A Polygon of
Lat/Long Points Define "bounding area" OASIS Common Alerting Protocol (CAP)
"area" Polygon Defined by WGS84 (World Geodetic
System 1984) Lat/Long Points CAP "area" can also be “circle” from WGS84
Lat/Long "point" + radius length in kilometers

Geospatial Keys to Improving Rapid First Response
• Geospatial Concepts Support DRM: OASIS Common Alerting Protocol (CAP)
"area" Altitude and Ceiling can be used in CAP CAP “area” can be used by USGS & NOAA
Weather Service Systems which Forecast Storm Tracks, Tornado “Watch Boxes,” Toxic Plume Dispersal Patterns, Wildfires
Geospatial Information Systems (GIS) Critical in Emergency Incident Preparedness, First Response and Follow up Services.

Geospatial Keys to Improving Rapid First Response
• Geospatial Concepts Support DRM: Specific CRS or Geocode Defines DRM
"Context"

Semantic Interoperability• Simplified Analogies

Semantics Simplified• Semantics Defines Meanings
MEANINGS + DATA = USEFUL INFORMATION Geospatial Systems include Semantics
• Interoperability Needs Semantic Roadmaps, Guides, Dictionaries for Vocabularies AND Geospatial CRS
• Ontologies are Classification Systems used for Standard Vocabularies or Geospatial CRS Standards & Geopolitical Addressing Standards
• Ontologies Perform EQUALLY well for Geospatial Systems

How are we Showing Semantic Interoperability?
• We Use Standards from the Organization for the Advancement of Structured Information Standards (OASIS)
• Common Alerting Protocol (CAP) 1.0 1.1 Recently Approved as OASIS Standard, Pilot
uses 1.0 • Emergency Data Exchange Language
Distribution Element (EDXL_DE) 1.0 Committee Specification
Simulated Event Type & Sender/Recipient Type Ontologies Drive Improved Message Routing
Simulated Event Type also Drives Lookup for Secondary Healthcare & Geospatial Services

Semantic Interoperability Summary
• Teamwork Through Semantically Ordered Web Services
• Registries Allow Related Companies/Entities to Locate Each Other
• Registries Allow Resources to be Located and Bound through Web Services
• Registries Add Layer of Role-Based Security• Third Party Portals and Communities, such
as Geospatial and Healthcare Can Aid Preparedness through Semantically Ordered, PreRegistered Web Services
