Geographic information - Geospatial API for features - Part 1: Core (ISO 19168-1:2020)
This document specifies the behaviour of Web APIs that provide access to features in a dataset in a
manner independent of the underlying data store. This document defines discovery and query
operations.
Discovery operations enable clients to interrogate the API, including the API definition and metadata
about the feature collections provided by the API, to determine the capabilities of the API and retrieve
information about available distributions of the dataset.
Query operations enable clients to retrieve features from the underlying data store based upon simple
selection criteria, defined by the client.

Le présent document spécifie le comportement des API Web donnant accès aux entités d'un jeu de données indépendamment du système sous-jacent de stockage de données. Le présent document définit les opérations de découverte et d'interrogation.
Les opérations de découverte permettent aux clients d'interroger l'API, y compris la définition et les métadonnées de l'API concernant les collections d'entités fournies par l'API, pour déterminer les capacités de l'API et extraire des informations relatives aux distributions disponibles de jeux de données.
Les opérations d'interrogation permettent aux clients d'extraire des entités du système sous-jacent de stockage de données sur la base de critères de sélection simples définis par le client.

Introduction
[9]
OGC API standards define modular API building blocks to spatially enable Web APIs in a consistent
manner. The OpenAPI specification is used to define the API building blocks.
The OGC API family of standards is organized by resource type. This document specifies the
fundamental API building blocks for interacting with features. The spatial data community uses the
term 'feature' for things in the real world that are of interest.
For those not familiar with the term 'feature,' the explanations on Spatial Things, Features and
Geometry in the W3C/OGC Spatial Data on the Web Best Practice document provide more detail.
OGC API Features provides API building blocks to create, modify and query features on the Web.
OGC API Features is comprised of multiple parts, each of them a separate standard. This document,
the "Core", specifies the core capabilities and is restricted to fetching features where geometries are
represented in the coordinate reference system, WGS 84, with axis order longitude/latitude. Additional
capabilities that address more advanced needs will be specified in additional parts. Examples include
support for creating and modifying features, more complex data models, richer queries, additional
coordinate reference systems, multiple datasets and collection hierarchies.
By default, every API implementing this document will provide access to a single dataset. Rather than
sharing the data as a complete dataset, the OGC API Features standards offer direct, fine-grained access
to the data at the feature (object) level.
The API building blocks specified in this document are consistent with the architecture of the Web.
In particular, the API design is guided by the IETF HTTP/HTTPS RFCs, the W3C Data on the Web
Best Practices, the W3C/OGC Spatial Data on the Web Best Practices and the emerging OGC Web API
Guidelines. A particular example is the use of the concepts of datasets and dataset distributions as
defined in DCAT and used in schema.org.
This document specifies discovery and query operations that are implemented using the HTTP GET
method. Support for additional methods (in particular POST, PUT, DELETE, PATCH) will be specified in
additional parts.
Discovery operations enable clients to interrogate the API, including the API definition and metadata
about the feature collections provided by the API, to determine the capabilities of the API and retrieve
information about available distributions of the dataset.
Query operations enable clients to retrieve features from the underlying data store based upon simple
selection criteria, defined by the client.
A subset of the OGC API family of standards is expected to be published by ISO. For example, this
document is published by ISO as ISO 19168-1. To reflect that only a subset of the OGC API standards
will be published by ISO and to avoid using organization names in the titles of ISO standards, standards
from the "OGC API" series are published by ISO as "Geospatial API," i.e. the title of this document in OGC
is "OGC API — Features — Part 1: Core" and the title in ISO is "Geographic Information — Geospatial
API for features — Part 1: Core."
For simplicity, this document consistently uses:
— "OGC API" to refer to the family of standards for geospatial Web APIs that in ISO is published as
"Geospatial API;"
— "OGC API - Features" to refer to the multipart standard for features that in ISO is published as
ISO 19168 / "Geographic Information - Geospatial API for features;"
— "OGC API - Features — Part 1: Core" to refer to this document that in ISO is published as ISO 19168-1
/ "Geographic Information - Geospatial API for features — Part 1: Core."

A subset of the OGC API family of standards is expected to be published by ISO. For example, this
document is published by ISO as ISO 19168-1. To reflect that only a subset of the OGC API standards
will be published by ISO and to avoid using organization names in the titles of ISO standards, standards
from the "OGC API" series are published by ISO as "Geospatial API," i.e. the title of this document in OGC
is "OGC API — Features — Part 1: Core" and the title in ISO is "Geographic Information — Geospatial
API for features — Part 1: Core."
For simplicity, this document consistently uses:
— "OGC API" to refer to the family of standards for geospatial Web APIs that in ISO is published as
"Geospatial API;"
— "OGC API - Features" to refer to the multipart standard for features that in ISO is published as
ISO 19168 / "Geographic Information - Geospatial API for features;"
— "OGC API - Features — Part 1: Core" to refer to this document that in ISO is published as ISO 19168-1
/ "Geographic Information - Geospatial API for features — Part 1: Core."

INTERNATIONAL STANDARD ISO 19168-1:2020(E)
Geographic information — Geospatial API for features —
Part 1:
Core
1 Scope
This document specifies the behaviour of Web APIs that provide access to features in a dataset in a
manner independent of the underlying data store. This document defines discovery and query
operations.
Discovery operations enable clients to interrogate the API, including the API definition and metadata
about the feature collections provided by the API, to determine the capabilities of the API and retrieve
information about available distributions of the dataset.
Query operations enable clients to retrieve features from the underlying data store based upon simple
selection criteria, defined by the client.
