Overview
ISO 19150-2:2015/Amd 1:2019 is an important amendment to the international standard on geographic information ontology, specifically focusing on rules for developing ontologies using the Web Ontology Language (OWL). Published by the International Organization for Standardization (ISO), this amendment refines and clarifies practices to enhance semantic interoperability in geographic information systems (GIS).
This standard plays a crucial role in guiding developers and organizations in creating consistent, reusable, and interoperable ontologies tailored for geographic data. By integrating OWL with concepts from SKOS (Simple Knowledge Organization System), it supports advanced data sharing and knowledge management across diverse geospatial systems.
Key Topics
-
Ontology Development in OWL
The standard emphasizes strict rules for designing ontologies with OWL, ensuring clear semantic definitions for geographic concepts and their relationships.
-
Code List Implementation
A key correction in Amendment 1 involves the construction of codelists as OWL classes, SKOS ConceptSchemes, and SKOS Collections. This provides a structured way to represent controlled vocabularies or code sets with precise annotations.
-
Semantic Annotation
Each ontology resource must be annotated with labels (rdfs:label) and source definitions (rdfs:isDefinedBy). This guarantees transparency and traceability for ontology elements.
-
Integration of OWL and SKOS
The amendment clarifies how OWL classes relate to SKOS concepts and collections, using properties like dct:isFormatOf, skos:inScheme, and skos:member for semantic consistency.
-
RDF Serialization Examples
Practical RDF/Turtle and RDF/XML examples illustrate compliant implementations of codelists and ontologies, guiding developers on correct syntax and meaningful structure.
Applications
-
Geographic Information Systems (GIS)
Enables standardized ontology development to improve data sharing and integration across GIS platforms, enhancing geographic data analysis and decision-making.
-
Semantic Web and Linked Data
Facilitates publishing and connecting geographic ontologies on the web using OWL and SKOS, supporting more intelligent retrieval and interoperability in linked data ecosystems.
-
Spatial Data Infrastructure (SDI) Development
Supports creation of interoperable ontologies vital for SDI initiatives, promoting harmonized metadata and semantic clarity for geographic datasets.
-
Knowledge Management in Geomatics
Provides a framework for organizing geospatial concepts and vocabularies systematically, aiding knowledge transfer and reuse in geomatics research and industry.
-
Standards Compliance for Software Tools
Guides vendors in implementing ontology modeling tools and GIS software to comply with international best practices, enhancing cross-platform compatibility.
