Overview
ISO/TS 19150-1:2012 - Geographic information - Ontology - Part 1: Framework defines a high‑level framework to achieve semantic interoperability of geographic information using ontologies. It describes the logical components and relationships needed to represent, share and reason about the meaning of geographic data within the ISO geographic information family of standards. The Technical Specification positions ontologies (formal vocabularies, definitions and axioms) as the foundation for machine‑processable semantics on the Semantic Web and for Linked Data integration.
Key topics and technical requirements
- Framework model: a high‑level model of components required to handle semantics across ISO geographic information standards (ontologies, registries, service ontologies, harmonized ontologies).
- Conformance: documents claiming conformance must meet the requirements in the abstract test suite (Annex A).
- Ontology representation: formal ontologies represented as classes, relations, properties and axioms to support reasoning, interpretation and inference.
- Rules for OWL: the framework references development rules (expanded in Part 2) for producing ontologies in the Web Ontology Language (OWL/OWL‑DL) and mappings from UML conceptual models.
- Registries and services: conceptual components for a domain ontology registry and a service ontology registry to manage discovery, maintenance and reuse of ontologies.
- Harmonized ontologies: OWL‑DL translations that complement ISO/TC 211 UML models to enable cross‑standard semantic alignment.
- Semantic operators and spatial reasoning: addresses the need to introduce semantic and spatial operators (further specified in later parts) to support geographic reasoning on the Web.
- Supporting materials: informative annexes provide background on ontologies (Annex B) and ontology matching approaches (Annex C).
Practical applications and users
ISO/TS 19150-1 is primarily targeted at:
- Standards developers creating or updating ISO geographic information standards to include semantic definitions.
- Information system architects and analysts designing interoperable geospatial solutions that require machine‑readable semantics.
- Program planners and software developers implementing Linked Data, Semantic Web services, or OWL‑based domain models for geospatial data integration.
Practical applications include semantic integration of heterogeneous geospatial datasets, enhanced metadata interoperability, automated reasoning for feature interpretation, and discovery of ontology‑driven web services.

- Planned parts: semantic operators, service ontology, domain/service ontology registries
- Normative references include ISO/TS 19103, ISO 19109, ISO 19119 and ISO 19135
- Harmonized ontologies from ISO/TC 211 provide OWL‑DL translations of UML models
