Technical Implementation

CCO provides a broader and more general ontology for modeling entities, processes, qualities, and relationships, making it suitable for semantic interoperability across domains.

EDR is narrower and focuses specifically on environmental data retrieval through APIs, with concepts.

Table 1 below provides a mapping between CCO and OGC EDR showing the BroaderThan, NarrowerThan and similar concepts

Table 1. Cross-Walk between CCO and OGC EDR

Link/Bridge Concepts

The Link/bridge concepts in the shared ontology are used to align and integrate the Common Core Ontologies (CCO) and the OGC Environmental Data Retrieval (EDR). These bridge concepts ensure that the two ontologies can be interoperable. Table 2 below shows the bridge relationships between CCO and EDR.

Table 2: Bridge concepts between CCO and EDR

Bridge/Link Concept CCO Concept OGC EDR Concept
EnvironmentalData cco:InformationContentEntity edr:EnvironmentalData
Sensor cco:Device edr:Sensor
Observation cco:Process edr:Observation
FeatureOfInterest cco:Object edr:FeatureOfInterest
Measurement cco:QualityValue edr:Measurement
Location cco:SpatialLocation edr:Location
Time cco:TemporalLocation edr:Time
hasLocation cco:hasSpatialLocation edr:hasLocation
hasTime cco:hasTemporalLocation edr:hasTime
observes cco:performs edr:observes

Using the bridge concepts and the concept mappings described above the shared ontology is shown below.

Shared Ontology (ccoedr):

The Shared ontology or reference ontology (ccoedr) serves as the top level ontology that has more expressive terminology. Below is the shared ontology representationin OWL.
