Methodology

Understanding the Terminology of the Representations and Key Steps in Developing the Shared Ontology:

Overview

• OGC EDR focuses on retrieving environmental data, describing spatial-temporal metadata, and access patterns.
• CCO is designed for general-purpose use across domains, emphasizing logical formalism and consistency for entities, processes, and roles.

Capturing Similar/Broader/Narrower Concepts and Properties

Environmental Entities

Includes phenomena like weather, climate, water bodies, and ecological features.

Spatio-Temporal Aspects

Both representations address time, location, and spatial geometries.

Processes and Roles

• Processes: e.g., data retrieval, environmental phenomena.
• Roles: e.g., data provider, data consumer.

Identifying Similar Concepts and Bridging Classes/Properties for Alignment

• Use CCO’s upper ontology structure to align with EDR concepts, ensuring compatibility.
• Define equivalence relationships (e.g., owl:equivalentClass or owl:equivalentProperty) for similar concepts.
• Introduce bridge classes or properties where concepts and properties are narrower or broader.
