The Geography Markup Language (GML) is an XML encoding in compliance with ISO 19118 for the transport and storage of geographic information modelled in accordance with the conceptual modelling framework used in the ISO 19100 series of International Standards and including both the spatial and non-spatial properties of geographic features.

This International Standard defines the XML Schema syntax, mechanisms and conventions that:

* provide an open, vendor-neutral framework for the description of geospatial application schemas for the transport and storage of geographic information in XML;

* allow profiles that support proper subsets of GML framework descriptive capabilities;

* support the description of geospatial application schemas for specialized domains and information communities;

* enable the creation and maintenance of linked geographic application schemas and datasets;

* support the storage and transport of application schemas and datasets;

* increase the ability of organizations to share geographic application schemas and the information they describe.

Implementers may decide to store geographic application schemas and information in GML, or they may decide to convert from some other storage format on demand and use GML only for schema and data transport.

NOTE If an ISO 19109 conformant application schema described in UML is used as the basis for the storage andtransportation of geographic information, this International Standard provides normative rules for the mapping of such an application schema to a GML application schema in XML Schema and, as such, to an XML encoding for data with a logical structure in accordance with the ISO 19109 conformant application schema.

This part of ISO 19150 sets a framework for geographic information service ontology and the description of geographic information Web services in OWL.

The Web Ontology Language (OWL) is the language adopted for ontologies.

This part of ISO 19150 will make use of service metadata (ISO 19115-1) and service definition (ISO 19119) whenever appropriate

This part of ISO 19150 does not define semantics operators, rules for ontologies, and does not develop any application ontology.

In reference to ISO 19101-1:2014, Clause 6.2, this part of ISO 19150 defines and formalizes the following purpose of the ISO geographic information reference model:

* geographic information service components and their behaviour for data processing purposes over the Web, and

* OWL ontologies to cast ISO/TC 211 standards to benefit from and support the Semantic Web.

In reference to ISO 19101-1:2014, Clause 8.3, this part of ISO 19150 addresses the Meta:Service foundation of the ISO geographic information reference model.
