Phạm vi áp dụng / Scope of standard

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 and transportation 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.
